Hello :) My iOS project does not work with SwiftUI Preview in Xcode 14 beta. The project builds and runs fine, but Preview never works. The error message is as follows. HumanReadableSwiftError SettingsError: noExecutablePath(<IDESwiftPackageStaticLibraryProductBuildable:ObjectIdentifier(0x000060002ac3e880):'AppCenterCrashes'>) I do use the AppCenterCrashes dependency in my project. But I'm not sure if this error message is accurate, because sometimes it reports other packages. After I executed Generate Report, I found the following error in SerializationErrors.txt. Error Domain=NSCocoaErrorDomain Code=516 "“LogCaffeineIntent.swift” couldn’t be linked to “Intermediates” because an item with the same name already exists." UserInfo={NSSourceFilePathErrorKey=/Users/gong/Library/Developer/Xcode/DerivedData/.../Build/Intermediates.noindex/HiCoffee.build/Debug-iphonesimulator/IntentsExtension.build/DerivedSources/IntentDefinitionGenerated/Intents/LogCaffeineIntent.swift, NSUserStringVariant=( Link ), NSDestinationFilePath=/var/folders/lv/58r5dhv52j779_qn41gnq4c80000gn/T/previews-diagnostics-20220608-144336/Intermediates/LogCaffeineIntent.swift, NSFilePath=/Users/gong/Library/Developer/Xcode/DerivedData/.../Build/Intermediates.noindex/HiCoffee.build/Debug-iphonesimulator/IntentsExtension.build/DerivedSources/IntentDefinitionGenerated/Intents/LogCaffeineIntent.swift, NSUnderlyingError=0x600033223810 {Error Domain=NSPOSIXErrorDomain Code=17 "File exists"}} The problem seems to be related to the Intent generation code. I don't know how to fix it yet.

In Xcode 15 beta 6, building any Mac Catalyst project will encounter the following Linker warning. ld: warning: building for 'macCatalyst', but linking in dylib (/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa.tbd) built for 'macOS'

Hello, In Xcode 15 beta 3, if a project embedded a Swift package (no matter static or dynamic), and the package has its own dependencies, the linker will always emit following warning: ld: warning: duplicate -rpath '/Users/.../Library/Developer/Xcode/DerivedData/MyApp.../Build/Products/Debug-iphonesimulator/PackageFrameworks' ignored The warning is not appeared on beta 2 and beta 1. Reproduce Steps [1] Create a new iOS project in Xcode 15 beta 3 [2] Create a new Swift package MyLibrary, and add any dependency in the Package.swift. Example: // swift-tools-version: 5.9 import PackageDescription let package = Package( name: "MyLibrary", platforms: [.iOS(.v16)], products: [ .library(name: "MyLibrary", targets: ["MyLibrary"]), ], dependencies: [ // 👀 Add any dependency to this package. // Here I use "Version" which is a simple pure swift package: .package(url: "https://github.com/mxcl/Version.git", .upToNextMajor(from: "2.0.0")), ], targets: [ .target(name: "MyLibrary", dependencies: ["Version",]), ] ) [3] In the project page, embed MyLibrary into the iOS app target. [4] Build the project. It will succeed but with link warnings. In addition, if you create a dynamic framework and embed MyLibrary, the warnings also reproduce. And this is only a simple case. In my real project, the linker will also emit a lot of warnings like this: ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$__TtP10SPConfetti18SPConfettiDelegate_ ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$__TtP10SPConfetti18SPConfettiDelegate_ ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionTaskDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDataDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSURLSessionDownloadDelegate ld: warning: could not associate debug note to atom l_OBJC_LABEL_PROTOCOL_$_NSObject ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionTaskDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDataDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSURLSessionDownloadDelegate ld: warning: could not associate debug note to atom l_OBJC_PROTOCOL_REFERENCE_$_NSObject

I found a problem with the latest Xcode 13.2/13.2.1 when compiling SwiftUI if-#available structure. When building with Release mode, the app always crashes on an older system. import SwiftUI struct ContentView: View {   var body: some View {     List {       if #available(iOS 15.0, *) {         Text("Hello").badge(1)       } else {         Text("Hello") // 💥 always crash: iOS 14 + release mode       }     }   } } Sample crash log: OS Version: iPhone OS 14.8.1 (18H107) Release Type: User Baseband Version: n/a Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000000 VM Region Info: 0 is not in any region.

Hello everyone! I found that the Xcode Cloud workflows under my project are completely stuck. The tasks that are already running cannot be completed. Newly started tasks remain in the queued state forever and cannot be canceled. They are consuming my usage quota 😢. Has anyone else encountered the same issue?

Hello, I'm unable to run any test cases in Xcode 16 with the iOS 18 simulator. Steps to Reproduce: Create a new iOS project in Xcode 16 using the default iOS app template with the testing option checked. Run any test or UI test case by clicking the "Play" icon in the Test navigator. Xcode gets stuck at the "Testing" state indefinitely. Environment: macOS 15 beta 8 Xcode 16 beta 6 iOS 18 beta 7 simulator

In iOS 17 beta 4, the Live Activity on lock screen is always rendered in dark mode. The issue can be reproduced both on physical device and simulator.

Hello, When an iOS app runs on Vision Pro in compatible mode, is there a flag such as isiOSAppOnVision to determine the underlying OS at runtime? Just like the ProcessInfo.isiOSAppOnMac. It will be useful to optimize the app for visionOS. Already checked but not useful: #if os(xrOS) does not work in compatible mode since no code is recompiled. UIDevice.userInterfaceIdiom returns .pad instead of .reality. Thanks.

Hello! I can't preview the SwiftUI views of watchOS target in Xcode 15 beta 1, when the containing iOS app has a SPM dependency. Reproducing steps: Create a new watchOS app project (with a companion iOS app) in Xcode 15. Both iOS and watchOS ContentView can be previewed at this step. Add a Swift package to the iOS target (the package should be an iOS-specific package, not a watchOS one, for example, https://github.com/siteline/SwiftUI-Introspect) After you add the static library to iOS target, the watchOS preview no longer work anymore. If you check the error message, you can find the Xcode preview attempt to build the iOS package against watchOS SDK.

Hello! Two of my watch apps (HiCoffee and HiWater) occasionally have issues with complications not displaying properly on watchOS 9. I did NOT use the new WidgetKit to implement the complications, all the related code still uses the same previous ClockKit + SwiftUI. I have observed several different types of wrong behaviors. One specific complication cannot be displayed (rendered?), while others do work (from the same app). This indicates that my watch app is working properly. All complications on the face cannot be displayed. But the app logs indicates it's running properly. In addition, when you long press the face to edit complications, yet it can be displayed normally. Log shows CLKComplicationServer.sharedInstance().activeComplications always returns 0 no matter how many complications are added to the face. Also, the ComplicationController is NOT called by system. I'm not using WatchKit. This part of the code in my app has been working properly for a long time and has not been changed. But after the release of watchOS 9, I received a lot of feedback from users with this problem. So I think the problem is in watchOS 9. I haven't found a way to reproduce the problem yet. Any suggestions please?

Hello everyone! When I run UI Tests on Xcode Cloud, I often encounter unexpected failures. Checking the screen recording, I found that the iOS Simulator could go into a black screen with a white Apple logo and a progress bar for a period after the test starts. This behavior of the Simulator causes my app's UI Tests to fail randomly, which greatly affects the practical use of UI Tests. I suspect this phenomenon is unrelated to my app and test cases, so I'm asking if anyone else has encountered a similar issue. 🤔

Hello! I've noticed that adding localizations for AppShortcuts triggers the following warnings in Xcode 15.3: warning: missing the definition of zh-Hans # variables.1.definitions warning: missing the definition of zh-Hans # variables.2.definitions This occurs with both legacy strings files and String Catalogs. Example project: https://github.com/gongzhang/AppShortcutsLocalizationWarningExample

Hello, I found that ScrollViewProxy.scrollTo(_:anchor:) always crash on iOS 16 beta 1-7.

Hello! I found that on the latest macOS 13 Ventura, my iOS app (iOS-App-On-Mac-With-M1/M2-Chip) is not able to restore IAP purchases or refresh receipt anymore. When using SKReceiptRefreshRequest() to refresh the IAP receipt, I got following error. Error Domain=SKErrorDomain Code=0 "An unknown error occurred" UserInfo={ NSLocalizedDescription=An unknown error occurred, NSUnderlyingError=0x1330c1840 { Error Domain=ASDErrorDomain Code=500 "(null)" UserInfo={ NSUnderlyingError=0x13338ebf0 { Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “receipt” in the folder “StoreKit”." UserInfo={ NSFilePath=/Users/***/Library/Containers/EC7E888F-3388-418A-92C5-9CBDDC4A1846/Data/StoreKit/receipt, NSUnderlyingError=0x13333a790 { Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" } } } } } } It seems that the receipt cannot be refreshed due to a file permission issue. Also, the SKPaymentQueue.default().restoreCompletedTransactions() function does not get the purchases properly (but also does not report an error). This issue only appears in my iOS app on macOS 13 Ventura.
