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.

Hello There! I will try to be very active! (I had nothing to type lol)

Is SFSymbol Customization officially valid as a method for using SVG in embedded widgets (lock-screen & watchOS)? I use this in UnitedPizzaHelper but wonder whether this is the prime cause why all widgets of this app gets missing on iOS devices? This issue only happened on at least 2 device in the recent 12 months (they are all on iOS 18, and one of them is running iOS 18.5... Rebooting device won't work.), and we currently have no clue how to troubleshoot this. Update: The guy running iOS 18.5 told me that the widgets are now discoverable after waiting for minutes. Seems that this is a random issue.

On my M4 Mac running macOS 15.5 using Xcode 16.4 & Xcode CLT 16.4, Swift code in my Swift Package Manager 5.9 project (https://github.com/mas-cli/mas) builds fine against some included Objective-C headers via the following command line: swift build -c release But cannot find modules for the included Objective-C headers when building inside Xcode 16.4 or with the following command line on the same Mac: xcodebuild -scheme mas -configuration Release -destination platform=macOS,arch=arm64,variant=macos The error is: Sources/mas/AppStore/AppleAccount.swift:9:16: error: no such module 'StoreFoundation' How can I get Xcode / xcodebuild to work? Note that the project is normally built by running: Scripts/build which runs: swift build -c release after running the following script, which must be run before any build (swift, Xcode, or xcodebuild) because it generates a necessary file (Sources/mas/Package.swift): Scripts/generate_package_swift I've tried moving the Objective-C headers into include subfolders of their existing module folders, using double quotes instead of angle brackets for the #import statements, having module.modulemap files in the include subfolders or their parent module folder, and moving the module folders one level up the file hierarchy, to no avail. I've also tried various changes to the root-level Package.swift (not the generated one deeper in the hierarchy, which isn't inclined in the build configuration), like making separate library targets for each of the Objective-C modules, various swiftSettings & linkerSettings, etc. Maybe some of those changes would have helped, but maybe they were in incorrect combinations. Thanks for any help.

Hello, I'm working on a Unity game which uses Apple Arcade Cloudkit Unity plugin. Cloud save works on all platforms except visionOS. I tried to debug using visionOS 2.4 Simulator. When the game starts XCode display the following error: DllNotFoundException: Unable to load DLL 'CloudKitWrapper'. Tried the load the following dynamic libraries: Unable to load dynamic library '/CloudKitWrapper' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen(/CloudKitWrapper, 0x0005): tried: '/Users/seb/Library/Developer/Xcode/DerivedData/Unity-VisionOS-akwybgjotadlwrghmmfkhbhpuduf/Build/Products/Debug-xrsimulator/CloudKitWrapper' (no such file), '/Library/Developer/CoreSimulator/Volumes/xrOS_22O237/Library/Developer/CoreSimulator/Profiles/Runtimes/xrOS 2.4.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/introspection/CloudKitWrapper' (no such file), '/Library/Developer/CoreSimulator/Volumes/xrOS_22O237/Library/Developer/CoreSimulator/Profiles/Runtimes/xrOS 2.4.simruntime/Contents/Resources/RuntimeRoot/CloudKitWrapper' (no such file), '/CloudKitWrapper' (no such file) at Apple.CloudKit.CKContainer.CKContainer_Default () [0x00000] in <00000000000000000000000000000000>:0 at Apple.CloudKit.CKContainer.Default () [0x00000] in <00000000000000000000000000000000>:0 I opened up the "Debug-xrsimulator" and indeed there is no CloudKitWrapper. However, if I "show content" on the app and navigate to the "Frameworks" folder, all Apple Arcade plugins are here, including CloudKit. I guess the plugin is in the right location, but the code tries to load it from the wrong path.

The “Deployment Targets” for iOS was IOS12 or higher in Xcode15, but is now listed as IOS15 or higher in Xcode16. https://developer.apple.com/support/xcode/ How does this change affect developers and users? For example, if a developer specifies less than iOS15 in the “iOS Deployment Target” on Xcode, how will this affect them? Also, will users under iOS 15 be unable to run the apps?

Hi, I have a question about obtaining the MDM Vendor CSR Signing Certificate. Is it possible to obtain this certificate with an Apple Developer Program account? From the official documentation below, it seems like it might be possible: https://developer.apple.com/help/account/certificates/mdm-vendor-csr-signing-certificate/ However, I have also seen past forum posts stating that it is only available through the Apple Developer Enterprise Program: https://developer.apple.com/forums/thread/671716 If anyone has detailed knowledge about this, I would greatly appreciate your guidance.

We have started facing an issue after updating Xcode from version 15.2 to 16, we have a voip application with webview and call kit, and we have the Background Modes capabilities: Voip, Audio, Background fetch, and Background processing. We had no problem on Xcode 15, but ever since updating Xcode 16 and sdk 18, when app goes into the background during an active call, the app is suspended and no events are triggered UNTIL the app is resumed to the foreground.

Hi ~ May I know how long did you get your VisionOS developer kit? Thanks

First time user here. Trying to build my React-Native app on xcode. I keep getting "Could not build Module" and "missing package product" and tried many combination for my Podfile. I am on macbook pro M2, XCode version 16.2, building on iphone 16 v18.3.1. Pod version 1.16.2, react-native-cli:2.0.1, Here is my Podfile. I tried to assign modular_headers to individual Firebase packages but then I cant pod install. require_relative '../node_modules/react-native/scripts/react_native_pods' require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules' use_modular_headers! platform :ios, '18.0' prepare_react_native_project! target 'plana' do config = use_native_modules! use_react_native!( :path => config[:reactNativePath], :fabric_enabled => false, :app_path => "#{Pod::Config.instance.installation_root}/.." ) post_install do |installer| react_native_post_install( installer, config[:reactNativePath], :mac_catalyst_enabled => false, ) end end

This is the issues I faced: NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed How can I fix it because I'm not sure if I dowloaded the application correctly.

The code in my app is split into frameworks that I can use both from my main app and its app extensions. In order to use the frameworks inside the app extension, I need to build them with the Xcode build setting Require Only App-Extension-Safe API set to Yes. When I do that, debugging framework code in my main app no longer works properly. I can set a breakpoint, but any attempt to print a value via p or po will give a set of errors like the following: error: module file /Users/.../Library/Developer/Xcode/DerivedData/...-daqfgouagvlkudfebrmzrurogmld/Build/Intermediates.noindex/SwiftExplicitPrecompiledModules/_errno-B8I5WSZMM09RXHYLYEWSC1BLE.pcm cannot be loaded due to a configuration mismatch with the current compilation error: Objective-C App Extension was enabled in PCH file but is currently disabled How do I fix this?

Hi! I am having trouble getting my app to build successfully or archive since an xcode update a few months ago. Below is the error that shows in the log. Thank you in advance for any help!

I have enabled Code Review with the button and then String Catalog turned up to code view anyways i can't get it back to original view. Disable Code Review button doesn't do anything. Any idea?

I am trying to setup a unversal linking for my new developing app. but it look like not function well. did any one have some examples or demo domains suggest to use? In fact finally my app is just internal using, user will not suppose connect to internet , how can I using the universal linking without a website ? Thanks

So Xcode has projects. And I breakup my code/libraries/targets into those. So why after 20 years of Xcode, can a workspace, that holds projects not display the same project opened in another workspace? The workspace redirects all output the project would normally generate in DerivedData to a completely different folder by default. What this means is I have to shut one workspace, and then open the other workspace with a different set of projects to see the ones that are shared. The workspace can't build because it can't open the project shared with another one that is open. VS sln files don't have this issue, so why do workspace files.

For Xcode 15 and Xcode 16, whenever I try to use the Refactor->Rename command I get a spinning busy cursor for a short while then I get an alert that says: Rename Failed Refactoring engine failure. This happens on several projects and I've tried removing the derived data folder, but am at a loss to find additional troubleshooting steps. Are there other files I might remove or reset to get my "Refactoring Engine" back into shape?
