How can I add navigation to an existing program. I coded this as per youtube video: var body: some View { NavigationView { VStack { NavigationLink(destination: viewdetail()) { Text("click") .frame(width: 300, height: 150, alignment: .center) .background(Color.gray) .foregroundColor(.black) } } } It doesn't work. If I comment out the rest of the program it works. I have VStacks and HStacks and functions after the navigation code. Please help.

Hi everyone, Since a couple days, I can't launch my watchOS widget extension in the Xcode simulator. After launching the scheme in Debug or Release, I always end up with Xcode stuck on "Waiting to attach to watchOSWidgets on Apple Watch Series 9". I already uninstalled and reinstalled Xcode and cleared all Xcode related folders in Library. I also tried to use Debug > Attach to process, then Xcode goes into "Running watchOSWidgets on Apple Watch Series 9" but no widgets are installed, neither the app so I cannot debug anything. I tried on different simulators, always end up with the same problem. However, the watch app scheme works fine, in Debug or Release, it is only the widgets extension which doesn't work anymore. This seems related to my computer, because if I create an empty project with a default watch widget extension, I still have the same issue. I really don't know what to do... Does anyone has a clue ? Thanks

It only seems to happen in the real app I am working on and not within any of the test apps I make. Its lasted a few Xcode versions. Don't know if this is widespread to the point of having a name?

I'm using xcode 16.1 withSwiftUI. I want to know how to call a function passing in an array. Also I need to know how to declare the function receiving the array. I currently have: func myfunc(costa: [Double] { some code } I call it like this: myfunc(costa:[ ]) It's an array of Doubles. I don't get any errors but the array is always empty even though it's not empty on the sending side. Please help. Thank you.

I saw in the Xcode 16 release notes that on-device debugging is no longer available on watchOS prior to version 7.0, but I can't even get a signed, compiled app to run on an older watch. The current version I have live in the App Store works just fine on 4.3.2. I have changed no code, I just started building the app with Xcode 16, and now it won't launch on older watches. Is it no longer possible to update an app for older watches?

We use a local swift package in 6 of our app extensions. The product from the local package that we link to each app extension is a dynamic framework. And while the dynamic framework is copied into the final app bundle once, the resource bundles of each target that comprise the dynamic framework is copied into each app extension. I'd much rather have the bundles be copied into the dynamic framework once to prevent app bloat. Here is a visualization of the issue: . └── MyApp.ipa/ ├── MyApp (executable) ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle ├── MyDynamicFramework_TargetC.bundle ├── Frameworks/ │ └── MyDynamicFramework.framework/ │ ├── TargetA │ ├── TargetB │ └── TargetC └── PlugIns/ ├── Widgets.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── Intents.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── IntentsUI.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── NotificationContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── RichPushContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle └── NotificationService.appex/ ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle └── MyDynamicFramework_TargetC.bundle Notice that the resource bundles of Target A, B, and C are copied multiple times causing an unhealthy app size. I'd either like the resource bundles to be copied into MyDynamicFramework or copied once into the app bundle and let the app extensions reference them. Given the SPM + Xcode linking is a black box for the most part, how would I accomplish this?

Happy to have a new MacBook Pro M4 now - the new machine was setup from time machine backup of my old MacBook Pro M1. Sadly Predictive Code Completion does not work on the new M4 (it was working great on the M1). Xcode shows as downloaded component: Predictive Code Completion Model [com.apple.fm.code.generate_small_v1.base: 500.1.81600.13.200772,0] [com.apple.fm.code.generate_safety_guardrail.base: 1.6.81619.13.200716,0] [com.apple.gm.safety_deny.input.code_intelligence.base: 32024010.20241007.171244.100.377,0] [com.apple.gm.safety_deny.output.code_intelligence.base: 32024010.20241007.171244.100.377,0] (Installed) Things I already tried: Removed and reinstalled Xcode 16 (also latest beta). Disabled/enabled Xcode Editor Settings for predictive code completion Many many reboots Removed Xcode cache Maybe the downloaded Model is somehow locked to the old machine? How can I remove, redownload or reinstall it again? Thank you very much. Tobias

I am writing a package in Swift using Xcode 16.1 (swift-tools-version: 6.0) and am trying to use features that became available in later versions of macOS and iOS. The following line naturally causes a compiler error when compiling against 'My Mac': let match = "test-string".firstMatch(of: /-(.+)/)! 'firstMatch(of:)' is only available in macOS 13.0 or newer I can of course fix this by using @available(macOS 13.0, *), but there are dozens of methods and I would prefer to use the platforms property in the Package file like this: platforms: [ .macOS(.v10_13), .iOS(.v16) ], However for reason that are not clear, this does not work and the compiler errors remain. I have tried cleaning, removing derived data etc. What I am doing wrong?

I try to use "Download container" on "Devices and Simulators". But on iOS 17, xcappdata file size is 4KB and ''AppData" folder is empty. On iOS 15, xcappdata file size is 2MB and success downloaded. Xcode show these error when I unplug iOS 17 and plugin iOS 15. The system failed to get a list of files on the remote device. Domain: com.apple.dt.CoreDeviceError Code: 7001 User Info: { DVTErrorCreationDateKey = "2023-12-12 07:39:24 +0000"; NSFilePath = ""; } -- Unknown response: { XPCErrorDescription => Connection interrupted } Domain: com.apple.dt.remoteservices.error Code: -1 -- System Information macOS Version 14.2 (Build 23C64) Xcode 15.1 (22502) (Build 15C65) Timestamp: 2023-12-12T15:39:24+08:00 PS. I had turn on [Airplane mode] on iOS 17.

When I attempt to preview my code, I encounter an error message stating, “Cannot preview in this file: Failed to launch (App Name).” This issue is specific to this particular app. I attempted creating a new project, and that works fine. This is what it says in the diagnostics: | [Remote] JITError | | ================================== | | | [Remote] LLVMError | | | | LLVMError: LLVMError(description: "The file was not recognized as a valid object file")

Our company has been trying to register for the Apple Developer Enterprise Program since September 15, 2024. However, it wasn’t until early November that we received an email requesting our business information. Following that, we contacted Apple’s team on November 15, 2024, to answer their interview questions. Now, more than a month has passed since that call, and we still have no idea about the status of our approval. When I check the account, it always shows 'Your enrollment is being processed. Your enrollment ID is 8K8SXNKA89.' I’ve also emailed Apple Support but have not received any further response. How much longer will this process take? Apple’s handling of this is excessively slow and frustrating

Since Xcode 15.3 it has become impossible to build our project more twice in a row without encountering a batch of "internal inconsistency error: never received target ended message for target ID …". This issues appeared a few months ago (15.0 i think, but i'm not sure), but xcode 15.3 makes it almost unusable. We're a team of 3 iOS devs, and we're all having the problem. Our project involves a lot of SPM packages, a few cocoa pods, a few iOS Frameworks, and a bit of swiftgen. Nothing particularly special for a large project, and no custom build steps that does anything fancy. It is now to the point where we're looking for alternative to xcode, because we can't decently kill xcode and restart every time we have to build our code...

Today I got stuck with a weird behaviour with my c++ project. There is the code which doesn't catch exception from standard library (the same snippet works well on intel mac and under linux machines).

I am working on a hobby project to develop my own Bluetooth peripheral. The platform for this peripheral is a Espressif ESP32-based TinyS3 from Unexpected Maker. I have defined the bluetooth device & service information using custom UUIDs. Using nRF Connect or Light Blue mobile applications I can discover and connect to my device. I receive confirmation of this BLE connection and modifications to the my BLE Service from my code on my TinyS3. I am attempting to write a custom software program that uses the onboard Mac Bluetooth hardware to detect this device. I am technically using Qt's Bluetooth infrastructure via PySide6 [python]. Despite being able to see my device in the mobile BLE applications, my software as well as the Mac Bluetooth System Services does not detect my BLE device. I am broadcasting advertising messages at a 250ms rate, and since they are findable by these mobile applications, I am wondering if MacOS has specific requirements for advertising data for what it considers as a "legitimate/ connectable" device. Any help would be greatly appreciated. Thank you!

We have a watchOS app in TestFlight that is currently crashing on any device running watchOS 11 and up. I have an older Apple Watch SE that's capped at 10.6.1 that can run the app just fine, but the same exact install on a newer device fails. This started happening after I updated my MacBook to macOS Sequoia and Xcode to 16. In order to get the Watch app to run on the 10.6.1 device, I had to change the Swift Optimization Level from -O to -Osize. I already filed Feedback on this (FB15691116). I've tried so many different things and have come up with nothing to show for it. When I look in the IPS file, I see that the crash point in my code on the watchOS 11 device is at KinesiaUOnWatch`@objc SessionDelegator.session(_:activationDidCompleteWith:error:): 0x3a3f48 <+0>: sub sp, sp, #0x60 0x3a3f4c <+4>: stp x26, x25, [sp, #0x10] 0x3a3f50 <+8>: stp x24, x23, [sp, #0x20] 0x3a3f54 <+12>: stp x22, x21, [sp, #0x30] 0x3a3f58 <+16>: stp x20, x19, [sp, #0x40] 0x3a3f5c <+20>: stp x29, x30, [sp, #0x50] 0x3a3f60 <+24>: add x29, sp, #0x50 0x3a3f64 <+28>: mov x19, x4 0x3a3f68 <+32>: mov x23, x2 0x3a3f6c <+36>: mov x22, x0 0x3a3f70 <+40>: mov w0, #0x0 ; =0 0x3a3f74 <+44>: bl 0x89818 ; symbol stub for: type metadata accessor for Swift.MainActor 0x3a3f78 <+48>: mov x24, x0 0x3a3f7c <+52>: adrp x25, 161 0x3a3f80 <+56>: ldr w25, [x25, #0x654] 0x3a3f84 <+60>: mov x20, x0 0x3a3f88 <+64>: bl 0x8980c ; symbol stub for: static Swift.MainActor.shared.getter : Swift.MainActor 0x3a3f8c <+68>: mov x21, x0 0x3a3f90 <+72>: adrp x0, 166 0x3a3f94 <+76>: add x0, x0, #0xc40 ; lazy protocol witness table cache variable for type Swift.MainActor and conformance Swift.MainActor : Swift.Actor in Swift Incident Identifier: 08E2F667-7965-4C86-B85E-9E2F03EAA963 Beta Identifier: AD390666-55CB-43B3-9B14-BD3E70F456EB Hardware Model: Watch6,1 Process: KinesiaUOnWatch [389] Path: /private/var/containers/Bundle/Application/B571E983-F2B0-40EF-9F0D-8C471CAEB3FB/KinesiaUOnWatch.app/KinesiaUOnWatch Identifier: com.glneurotech.kinesiau.watchapp Version: 5.1.0 (510271) AppStoreTools: 16B39 AppVariant: 1:Watch6,1:11 Beta: YES Code Type: ARM64_32 (Native) Role: Foreground Parent Process: launchd [1] Coalition: com.glneurotech.kinesiau.watchapp [464] Date/Time: 2024-12-03 15:12:51.1876 -0500 Launch Time: 2024-12-03 15:12:50.0000 -0500 OS Version: Watch OS 11.1 (22R585) Release Type: User Report Version: 104 Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000001, 0x000000002053dd4c Termination Reason: SIGNAL 5 Trace/BPT trap: 5 Terminating Process: exc handler [389] But, as I said, this exact app runs just fine on an older watchOS 10.6.1 device.

I'm creating a clean project in Expo without Typescript. I run the command “npx expo prebuild” normally, but when I run the command “npx expo run:ios” I get the error “PhaseScriptExecution [CP-User]\ Generate\ Specs /Users/bogdanlyamzin/Library/Developer/Xcode/DerivedData/testapp-gbckopevfunjmtanprbgmojuogrr/Build/Intermediates. noindex/Pods.build/Debug-iphonesimulator/ReactCodegen.build/Script-46EB2E0001C6B0.sh (in target 'ReactCodegen' from project 'Pods')”. Can you please tell me how to fix it? Translated with DeepL.com (free version)

After installing MacOS Sequoia, Xcode 16 & RealityComposer Pro 2 my Apple Vision Pro projects (worked perfectly with Xcode 15) started to give me Tool terminated by signal 'Segmentation fault: 11' error while compiling RealityKitContent assets. This happens only when I try to build project with .usdz models exported from Blender, but when I try with sample models from apple website it works nice with no errors. Is there any solution?

I recieve the error message "XOJITError: Could not create code file directory for session: Permission denied". I'm Using Xcode 16.2. It is an AppKit project using SwiftUI and it also happens if I create a clean project. Error log is attached. previews_diagnostics_summary.txt

The new console in Xcode 15 is so terrible bad. Is it possible to get back the old console ?
