Blocker: Registering simulator runtime with CoreSimulator failed.
Hello, FWIW I've been developing enterprise iOS apps going on 10 years and haven't seen a bug like this. It's a major blocker. Any advice is welcome. Pulled latest from my team's repository . I ran into a build issue. Reinstalled cocoa pods, resolved swift packages, cleared cache, and then tried to update my iOS simulators... Since then, everything is bricked. Can't side load an app or download a simulator. When I try to download simulator, as suggested by Xcode, I receive the following error: Registering simulator runtime with CoreSimulator failed. Domain: DVTDownloadableErrorDomain Code: 29 User Info: { DVTErrorCreationDateKey = "2025-05-28 19:18:13 +0000"; } Registering simulator runtime with CoreSimulator failed.

Trouble Distributing iOS + WatchOS App as a Bundle (Info.plist / Target Confusion)
Hi all, I’m running into an issue with my iOS + Apple Watch app project, and I could really use some advice. My WatchOS app requires an iOS companion for settings and configuration, so both apps need to be distributed together. Here’s how I structured my Xcode project: Main iOS App target WatchOS App target WatchOS Extension target However, I’m very confused about how these targets interact, and things are not working as expected. The problem: I can build and run the WatchOS app and its extension independently in the simulator by selecting their schemes. When I select the main iOS app scheme, I get an error about ITSWatchOnlyContainer in the Info.plist—even though there’s no Info tab for that target in Xcode. I’m able to distribute the WatchOS app by itself, and the extension as well. But I can’t distribute them bundled together as a single package, and I haven’t found any clear resources that explain how to fix this. This is my very first app, and it’s frustrating to get stuck just before the finish line! Project Structure / steps to reproduce Let’s say my project is called MyAppProject, with these targets: MyAppProject Main iOS App Embedded target: MyAppProject Watch App Bundle identifier: com.example.MyAppProject MyAppProject Watch App WKCompanionAppBundleIdentifier: com.example.MyAppProject “Requires iOS App”: YES MyAppProject Extension Bundle identifier: com.example.MyAppProject When running from the MyAppProject scheme, I get this error (even though I can’t see or edit the Info.plist in Xcode for this target): “Please try again later. This app has the ITSWatchOnlyContainer key set in its Info.plist, which identifies it as a shell app surrounding a Watch-only app; these are not installable.” As a result, I can’t distribute the app as a bundle. I’d appreciate help understanding: How should the Info.plist files be configured for each target? What do I do if the Info.plist path seems missing in the Xcode UI? Is there a “correct” way to structure an iOS + WatchOS app for bundled distribution?

The UT coverage does not include branch coverage for swift
We using below command to run unit test and collect coverage: xcodebuild -workspace Demo.xcworkspace -scheme VideoTests -configuration Debug -derivedDataPath ../build/derivedData -destination 'platform=iOS Simulator,id=E6630007-570B-4DEB-A023-2BCE91116A8D' -resultBundlePath './fastlane/test_output/VideoTests.xcresult' -enableCodeCoverage YES -testPlan 'Video' test-without-building | tee '/Users/rcadmin/Library/Logs/scan/VideoTests.log' | xcbeautify -q --is-ci and using xcrun llvm-cov show command to generate coverage report: xcrun llvm-cov show /build/unit-test/coverage/libraries/merged/video.o -instr-profile=/app/ios/build/derivedData/Build//ProfileData/E6630007-570B-4DEB-A023-2BCE91116A8D/video.profdata -show-branches count -show-expansions -show-line-counts -use-color -format=html -output-dir coverage and the html report does not include branch coverage: how to generate the branch coverage?

can't create info.plist from info-> URL Types
Hi, In Google Admob get started page they are suggesting to update info.plist file with keys. https://developers.google.com/admob/ios/quick-start#update_your_infoplist However, I can't find info.plist in the project folder. On the internet, there are videos suggesting to create info.plist file from pressing + under Targets -> info -> URL Types section. Unfortunately , I can't generate the info.plist using that method. How should I proceed? It is difficult to enter all the keys defined in the Google Admob link there are 40+ keys. Thank you for your help.

iOS Simulator Error: UnityFramework Incompatible Platform
Hey everyone, I'm encountering an issue when trying to run my iOS application, which integrates a Unity project, on the iOS Simulator. I'm consistently getting a dlopen error 232 related to UnityFramework.framework. The full error message is: Error loading ...UnityFramework.framework/UnityFramework (232): dlopen(...UnityFramework.framework/UnityFramework, 0x0109): tried: '...UnityFramework.framework/UnityFramework' (mach-o file (...UnityFramework.framework/UnityFramework), but incompatible platform (have 'iOS', need 'iOS-sim')) It seems like the UnityFramework.framework is built for a physical iOS device (ARM architecture), but the simulator requires a different architecture (x86_64 for Intel Macs or arm64 for Apple Silicon Macs). I've already tried: Cleaning the build folder in Xcode. Checking the "Frameworks, Libraries, and Embedded Content" settings in my target's General tab. Could anyone provide guidance on how to properly configure my Unity build or Xcode project to ensure UnityFramework.framework includes the necessary simulator architectures? Any specific build settings in Unity or Xcode, or steps to re-export/re-integrate the framework, would be greatly appreciated! Thanks in advance for your help!

iOS Simulator (18.4) crashes when user clicks allow for Speech Recognition permission popup
When a new application runs on iOS 18.4 simulator and tries to access the Speech Framework, prompting a request for authorisation to use Speech Recognition, the application will crash if the user clicks allow. Same issue in the visionOS 2.4 simulator. Using Swift 6. Report Identifier: FB17686186 /// Checks speech recognition availability and requests necessary permissions. @MainActor func checkAvailabilityAndPermissions() async { logger.debug("Checking speech recognition availability and permissions...") // 1.

Only see "Personal team" although I've been added to my company team
Hello, I've been added as an "App Manager" to a team of my company to which the app I'm developing belongs. I've received the invite e-mail, done all required step. On the websites (Apple Developer and App Store Connect), everything to be fine: I properly appear as a member of the team, I see the application, I can edit it. However, when I log in in Xcode with that account, I only see the "Personal team". Therefore, I got the error "Failed Registering Bundle Identifier" (which makes sense since the app belongs to the team of my company, not to my Personal team). Since the Apple ID I used is my personal Apple ID (which happens to be my personal email address), and I already done some stuff with it, I feared that there was a problem with this particular Apple ID. Therefore, we tried to add me to the team with my professional email address. This time, we added this address as a Developer in the Team. But still the same problem: When I tried to log in in Xcode with that 2nd address, I still only see the Personal team. Note that professional email address has never been used on any Apple product before. I also tried to log out / log in multiple times, restarting XCode, and still the same problem. What are we missing? How can I be able to select the right team in Xcode?

How can I add a folder to my app's bundle
In previous Xcode versions, it was possible to add a folder reference to a project, and in the copy resources build phase it would copy the folder the bundle, rather than the contents (i.e. the folder's contents would be nested inside a directory named after the folder). In Xcode 16.4, when creating a folder reference, the copy resources build phase will copy the contents of the folder to the bundle at the root level (not nested), like the old behavior when creating a group rather than a folder reference. If you look at the raw project.pbxproj file, it shows up as a "File System Synchronized Root Group" rather than a "File Reference". Is there a way to get the old behavior, aside from hand-editing the project.pbxproj file?

How can you have a framework which uses a 3rd party dependency and an app that uses the framework and also the same dependency?
Is this setup possible / have a solution: There is a .xcframework F, which uses a 3rd party library, lets call it L. There is an app which uses the xcframework The app also uses L Both the app and F use SPM to integrate L F is using L for its own internal purposes. F is providing some functionality to the app. How it implements that ideally should be a black box from the app's perspective. The app also happens to use L for its own purposes. I can't get this set up working, always get warnings about duplicate symbols when running the App. This will presumably be due to the fact there are separate copies of L in both F and A. So how can that be eliminated? Can F not statically like to L and use the App's version of L at runtime? If so how can Xcode be configured so that F can actually compile? Or vice versa - can the App not statically link in its own copy of L and use that in the framework? If so, similar questions, how to configure Xcode to set this up? I can't believe this is an obscure use case, yet after days of searching and reading documentation I can't find any solution. Note that I was able to get this going when the app and the framework used Cocoapods to integrate L, but I just can't do similarly if the use of Cocoapods is replaced with SMP. When using cocoapods, within the frameworks Xcode section, the pods framework is set to Do Not Embed. This is probably the vital difference between the working Cocoapods implementation and the not working SPM solution. However, when using SPM Xcode doesn't present any option to either embed nor not embed the dependency. Why not? Can it somehow be set to not embed?

app not playing audio when not in focus
My app works fine when I load it directly from Xcode to my phone via USB but once I load it to TestFlight the sounds no longer play when the app is not in focus or the phone is locked. I've tried every combination of tools available from the support group and from AI! And I'm out of ideas.

No models available in Xcode 26 beta Code Assistant
I have downloaded the new Xcode beta, signed in with my ChatGPT account yet there is still no model available for me to select. I have reinstalled Xcode, logged in and out of the ChatGPT integration a dozen times, pressed every single button, but nothing seems to make a model appear? Am I stupid or am I missing something?

Xcode forces my Macbook to restart when previewing canvas
I can't use Xcode without it crashing. Just writing a very simple iOS app with SwiftUI (using only forms and sections). Whenever my canvas updates to correspond to my changes it forces my Macbook to restart. Does anyone have a solution for this. I'll be honest it's becoming really frustrating. Thank you.

How to use a folder generated by an Xcode Aggregate Target as a resource in another target?
I have a multi target project where every target relies on a built "web bundle" which is basically a collection of html, optimized images, and optimized javascript. Right now that web bundle is built in a pre build step by running a script. The script takes awhile to run and outputs to a folder that is referenced into the project via a PBXFileReference which is then referenced in the Copy Bundle Resources step. 96516AC22BF928DD00576562 /* build */ = {isa = PBXFileReference; lastKnownFileType = folder; name = build; path = "../web-ui/build"; sourceTree = "<group>"; } .... 96516AC32BF928DD00576562 /* build in Resources */ = {isa = PBXBuildFile; fileRef = 96516AC22BF928DD00576562 /* build */; }; As a step, I wrote an aggregate target that can also run this script. I specified its input and output files and turned off sandboxing. It does exactly what I need it to. Critically it is ran based on dependency analysis. If I modify any file in web-ui it rebuilds, if I dont I can repeatedly build the aggregate target and it will not re-run the script. This is perfect. A97590172E419CBA00741928 /* Build Web Bundle */ = { isa = PBXShellScriptBuildPhase; buildActionMask = 12; files = ( ); inputFileListPaths = ( ); inputPaths = ( "$(SRCROOT)/xcodescripts/build-web-bundle.bash", "$(SRCROOT)/web-ui/index.html", "$(SRCROOT)/web-ui/vite-env.d.ts", "$(SRCROOT)/web-ui/vite.config.ts", "$(SRCROOT)/web-ui/tsconfig.json", "$(SRCROOT)/web-ui/stats.html", "$(SRCROOT)/web-ui/postcss.config.js", "$(SRCROOT)/web-ui/package.json", "$(SRCROOT)/web-ui/justfile", "$(SRCROOT)/web-ui/src/", ); name = "Build Web Bundle"; outputFileListPaths = ( ); outputPaths = ( "$(SRCROOT)/web-ui/build/", ); runOnlyForDeploymentPostprocessing = 0; shellPath = /bin/sh; shellScript = "exec \"${SCRIPT_INPUT_FILE_0}\"\n"; }; You may notice I reference a src file. This is made possible via a flag USE_RECURSIVE_SCRIPT_INPUTS_IN_SCRIPT_PHASES which allows Xcode to check folder dependencies recursively. The problem is that my other targets do not automatically recognize that they need to run the "WebBundle" aggregate target in order to update a resource they copy in their "Copy bundle resources" phase. So I tried adding it as a Target Dependency. A9DE685B2E41C9A8005EF4E0 /* PBXTargetDependency */ = { isa = PBXTargetDependency; target = A97590132E419C1200741928 /* WebBundle */; targetProxy = A9DE685A2E41C9A8005EF4E0 /* PBXContainerItemProxy */; }; Unfortunately this breaks whatever magic was allowing the script to be run only when there are web bundle changes. Every build it runs the "Build Web Bundle" script. I think what I am missing is a way to specify in these other targets that a resource they are used to copying from the Xcode PBXFileReference is produced by the aggregate target. This way they can start to reason about the dependencies. Other possibilities are that I should be building the web bundle to a separate location. Or that these references are somehow broken in another way. To be clear the folder format is as thus project/ iOS/ client.xcodeproj web-ui/ build/ (web bundle build is output here and referenced relatively) src/ index.html (and other things)

Device not detected
Trying to test applications on AVP as opposed to simulator. AVP can connect to MacBook via Mac virtual display so connection exists, but in X code under Windows devices the AVP does not show up same holds true on the AVP itself under remote devices. The MacBook Pro does not appear. I am signed in under the same account on the same Wi-Fi network. I have tried all basic troubleshooting. It is not clear to me that I am logged in as a developer, which could be the issue, but I am using OS 26, which does not appear to have the developer option under privacy and security where it used to reside in previous versions of the OS.

UIScene Storyboard - Main and Main_iphone
Under threat of future crashes, I'm adding support of UIScene to my existing apps. Each app has two storyboards - Main for iPads and Main_iphone for iPhones. Pre-UIScene, all looks great. With the addition of the Application Scene Manifest, the iPhone versions of the app are using the Main storyboard instead of the Main_iphone storyboard. Do I need to add an item to the plist for this other storyboard? At what level in the plist is this added? Another Scene Configuration? Another Window Application Session Role? Another Storyboard Name?

WatchOS app - installation not working
Hi everyone, I’ve been trying since yesterday to set up an Apple Watch app alongside my iOS app, but it’s not working at all. I created the app by adding a new target, selected watchOS > App, and linked it to my iOS project. When I run the Apple Watch scheme directly, the app works, but if I try to install it on my Apple Watch via the iOS app, it doesn’t work. Every time I tap install, I get a message saying that the installation failed. While reading the documentation, they mention an Info.plist file that is supposed to be generated with the watchOS app, but when I check, I don’t see any .plist file. Is that normal? Thanks for your help.

Trouble Distributing iOS + WatchOS App as a Bundle (Info.plist / Target Confusion)
Hi all, I’m running into an issue with my iOS + Apple Watch app project, and I could really use some advice. My WatchOS app requires an iOS companion for settings and configuration, so both apps need to be distributed together. Here’s how I structured my Xcode project: Main iOS App target WatchOS App target WatchOS Extension target However, I’m very confused about how these targets interact, and things are not working as expected. The problem: I can build and run the WatchOS app and its extension independently in the simulator by selecting their schemes. When I select the main iOS app scheme, I get an error about ITSWatchOnlyContainer in the Info.plist—even though there’s no Info tab for that target in Xcode. I’m able to distribute the WatchOS app by itself, and the extension as well. But I can’t distribute them bundled together as a single package, and I haven’t found any clear resources that explain how to fix this. This is my very first app, and it’s frustrating to get stuck just before the finish line! Project Structure / steps to reproduce Let’s say my project is called MyAppProject, with these targets: MyAppProject Main iOS App Embedded target: MyAppProject Watch App Bundle identifier: com.example.MyAppProject MyAppProject Watch App WKCompanionAppBundleIdentifier: com.example.MyAppProject “Requires iOS App”: YES MyAppProject Extension Bundle identifier: com.example.MyAppProject When running from the MyAppProject scheme, I get this error (even though I can’t see or edit the Info.plist in Xcode for this target): “Please try again later. This app has the ITSWatchOnlyContainer key set in its Info.plist, which identifies it as a shell app surrounding a Watch-only app; these are not installable.” As a result, I can’t distribute the app as a bundle. I’d appreciate help understanding: How should the Info.plist files be configured for each target? What do I do if the Info.plist path seems missing in the Xcode UI? Is there a “correct” way to structure an iOS + WatchOS app for bundled distribution?

can't create info.plist from info-> URL Types
Hi, In Google Admob get started page they are suggesting to update info.plist file with keys. https://developers.google.com/admob/ios/quick-start#update_your_infoplist However, I can't find info.plist in the project folder. On the internet, there are videos suggesting to create info.plist file from pressing + under Targets -> info -> URL Types section. Unfortunately , I can't generate the info.plist using that method. How should I proceed? It is difficult to enter all the keys defined in the Google Admob link there are 40+ keys. Thank you for your help.

iOS Simulator Error: UnityFramework Incompatible Platform
Hey everyone, I'm encountering an issue when trying to run my iOS application, which integrates a Unity project, on the iOS Simulator. I'm consistently getting a dlopen error 232 related to UnityFramework.framework. The full error message is: Error loading ...UnityFramework.framework/UnityFramework (232): dlopen(...UnityFramework.framework/UnityFramework, 0x0109): tried: '...UnityFramework.framework/UnityFramework' (mach-o file (...UnityFramework.framework/UnityFramework), but incompatible platform (have 'iOS', need 'iOS-sim')) It seems like the UnityFramework.framework is built for a physical iOS device (ARM architecture), but the simulator requires a different architecture (x86_64 for Intel Macs or arm64 for Apple Silicon Macs). I've already tried: Cleaning the build folder in Xcode. Checking the "Frameworks, Libraries, and Embedded Content" settings in my target's General tab. Could anyone provide guidance on how to properly configure my Unity build or Xcode project to ensure UnityFramework.framework includes the necessary simulator architectures? Any specific build settings in Unity or Xcode, or steps to re-export/re-integrate the framework, would be greatly appreciated! Thanks in advance for your help!

iOS Simulator (18.4) crashes when user clicks allow for Speech Recognition permission popup
When a new application runs on iOS 18.4 simulator and tries to access the Speech Framework, prompting a request for authorisation to use Speech Recognition, the application will crash if the user clicks allow.

Only see "Personal team" although I've been added to my company team
Hello, I've been added as an "App Manager" to a team of my company to which the app I'm developing belongs. I've received the invite e-mail, done all required step. On the websites (Apple Developer and App Store Connect), everything to be fine: I properly appear as a member of the team, I see the application, I can edit it. However, when I log in in Xcode with that account, I only see the "Personal team". Therefore, I got the error "Failed Registering Bundle Identifier" (which makes sense since the app belongs to the team of my company, not to my Personal team). Since the Apple ID I used is my personal Apple ID (which happens to be my personal email address), and I already done some stuff with it, I feared that there was a problem with this particular Apple ID. Therefore, we tried to add me to the team with my professional email address. This time, we added this address as a Developer in the Team. But still the same problem: When I tried to log in in Xcode with that 2nd address, I still only see the Personal team. Note that professional email address has never been used on any Apple product before. I also tried to log out / log in multiple times, restarting XCode, and still the same problem. What are we missing? How can I be able to select the right team in Xcode?

How can I add a folder to my app's bundle
In previous Xcode versions, it was possible to add a folder reference to a project, and in the copy resources build phase it would copy the folder the bundle, rather than the contents (i.e. the folder's contents would be nested inside a directory named after the folder). In Xcode 16.4, when creating a folder reference, the copy resources build phase will copy the contents of the folder to the bundle at the root level (not nested), like the old behavior when creating a group rather than a folder reference. If you look at the raw project.pbxproj file, it shows up as a "File System Synchronized Root Group" rather than a "File Reference". Is there a way to get the old behavior, aside from hand-editing the project.pbxproj file?

How can you have a framework which uses a 3rd party dependency and an app that uses the framework and also the same dependency?
Is this setup possible / have a solution: There is a .xcframework F, which uses a 3rd party library, lets call it L. There is an app which uses the xcframework The app also uses L Both the app and F use SPM to integrate L F is using L for its own internal purposes. F is providing some functionality to the app. How it implements that ideally should be a black box from the app's perspective. The app also happens to use L for its own purposes. I can't get this set up working, always get warnings about duplicate symbols when running the App. This will presumably be due to the fact there are separate copies of L in both F and A. So how can that be eliminated? Can F not statically like to L and use the App's version of L at runtime? If so how can Xcode be configured so that F can actually compile? Or vice versa - can the App not statically link in its own copy of L and use that in the framework? If so, similar questions, how to configure Xcode to set this up? I can't believe this is an obscure use case, yet after days of searching and reading documentation I can't find any solution. Note that I was able to get this going when the app and the framework used Cocoapods to integrate L, but I just can't do similarly if the use of Cocoapods is replaced with SMP. When using cocoapods, within the frameworks Xcode section, the pods framework is set to Do Not Embed. This is probably the vital difference between the working Cocoapods implementation and the not working SPM solution. However, when using SPM Xcode doesn't present any option to either embed nor not embed the dependency. Why not? Can it somehow be set to not embed?

app not playing audio when not in focus
My app works fine when I load it directly from Xcode to my phone via USB but once I load it to TestFlight the sounds no longer play when the app is not in focus or the phone is locked. I've tried every combination of tools available from the support group and from AI! And I'm out of ideas.

Whenever my canvas updates to correspond to my changes it forces my Macbook to restart. Does anyone have a solution for this. I'll be honest it's becoming really frustrating. Thank you.

How to use a folder generated by an Xcode Aggregate Target as a resource in another target?
I have a multi target project where every target relies on a built "web bundle" which is basically a collection of html, optimized images, and optimized javascript. Right now that web bundle is built in a pre build step by running a script. The script takes awhile to run and outputs to a folder that is referenced into the project via a PBXFileReference which is then referenced in the Copy Bundle Resources step. 96516AC22BF928DD00576562 /* build */ = {isa = PBXFileReference; lastKnownFileType = folder; name = build; path = "../web-ui/build"; sourceTree = "<group>"; } .... 96516AC32BF928DD00576562 /* build in Resources */ = {isa = PBXBuildFile; fileRef = 96516AC22BF928DD00576562 /* build */; }; As a step, I wrote an aggregate target that can also run this script. I specified its input and output files and turned off sandboxing. It does exactly what I need it to. Critically it is ran based on dependency analysis. If I modify any file in web-ui it rebuilds, if I dont I can repeatedly build the aggregate target and it will not re-run the script. This is perfect. A97590172E419CBA00741928 /* Build Web Bundle */ = { isa = PBXShellScriptBuildPhase; buildActionMask = 12; files = ( ); inputFileListPaths = ( ); inputPaths = ( "$(SRCROOT)/xcodescripts/build-web-bundle.bash", "$(SRCROOT)/web-ui/index.html", "$(SRCROOT)/web-ui/vite-env.d.ts", "$(SRCROOT)/web-ui/vite.config.ts", "$(SRCROOT)/web-ui/tsconfig.json", "$(SRCROOT)/web-ui/stats.html", "$(SRCROOT)/web-ui/postcss.config.js", "$(SRCROOT)/web-ui/package.json", "$(SRCROOT)/web-ui/justfile", "$(SRCROOT)/web-ui/src/", ); name = "Build Web Bundle"; outputFileListPaths = ( ); outputPaths = ( "$(SRCROOT)/web-ui/build/", ); runOnlyForDeploymentPostprocessing = 0; shellPath = /bin/sh; shellScript = "exec \"${SCRIPT_INPUT_FILE_0}\"\n"; }; You may notice I reference a src file. This is made possible via a flag USE_RECURSIVE_SCRIPT_INPUTS_IN_SCRIPT_PHASES which allows Xcode to check folder dependencies recursively. The problem is that my other targets do not automatically recognize that they need to run the "WebBundle" aggregate target in order to update a resource they copy in their "Copy bundle resources" phase. So I tried adding it as a Target Dependency. A9DE685B2E41C9A8005EF4E0 /* PBXTargetDependency */ = { isa = PBXTargetDependency; target = A97590132E419C1200741928 /* WebBundle */; targetProxy = A9DE685A2E41C9A8005EF4E0 /* PBXContainerItemProxy */; }; Unfortunately this breaks whatever magic was allowing the script to be run only when there are web bundle changes. Every build it runs the "Build Web Bundle" script. I think what I am missing is a way to specify in these other targets that a resource they are used to copying from the Xcode PBXFileReference is produced by the aggregate target. This way they can start to reason about the dependencies. Other possibilities are that I should be building the web bundle to a separate location. Or that these references are somehow broken in another way. To be clear the folder format is as thus project/ iOS/ client.xcodeproj web-ui/ build/ (web bundle build is output here and referenced relatively) src/ index.html (and other things)

Device not detected
Trying to test applications on AVP as opposed to simulator. AVP can connect to MacBook via Mac virtual display so connection exists, but in X code under Windows devices the AVP does not show up same holds true on the AVP itself under remote devices. The MacBook Pro does not appear. I am signed in under the same account on the same Wi-Fi network. I have tried all basic troubleshooting. It is not clear to me that I am logged in as a developer, which could be the issue, but I am using OS 26, which does not appear to have the developer option under privacy and security where it used to reside in previous versions of the OS.

UIScene Storyboard - Main and Main_iphone
Under threat of future crashes, I'm adding support of UIScene to my existing apps. Each app has two storyboards - Main for iPads and Main_iphone for iPhones. Pre-UIScene, all looks great. With the addition of the Application Scene Manifest, the iPhone versions of the app are using the Main storyboard instead of the Main_iphone storyboard. Do I need to add an item to the plist for this other storyboard? At what level in the plist is this added? Another Scene Configuration? Another Window Application Session Role? Another Storyboard Name?

WatchOS app - installation not working
Hi everyone, I’ve been trying since yesterday to set up an Apple Watch app alongside my iOS app, but it’s not working at all. I created the app by adding a new target, selected watchOS > App, and linked it to my iOS project. When I run the Apple Watch scheme directly, the app works, but if I try to install it on my Apple Watch via the iOS app, it doesn’t work. Every time I tap install, I get a message saying that the installation failed. While reading the documentation, they mention an Info.plist file that is supposed to be generated with the watchOS app, but when I check, I don’t see any .plist file. Is that normal? Thanks for your help.
