If I use the method callAsyncJavaScript() my app will compile, but it won't run on older simulators. Specifically, in a brand new Storyboard project, I added this to `viewDidLoad(): let webView = WKWebView() webView.callAsyncJavaScript("1", in: nil, in: .page) { result in print("\(result)") } This runs fine with Xcode 16.3 targeting the iOS 18.4 simulator. It doesn't work if I target the iOS 18.3.1 simulator or the iOS 17.5 simulator. It does work on an iPhone 15 Pro running iOS 18.4 and it works on an iPhone 12 Pro running iOS 17.7.1. It goes without saying that this used to work on Xcode 16.2 and earlier, since my real project has been using that API for 3 or 4 years now.

Recently, I’ve noticed that the Archive workflow on Xcode Cloud frequently fails randomly with the following error: ❌ Exporting for App Store Distribution failed. Please download the logs artifact for more information I’m not sure if this issue is on my side or if it’s related to Xcode Cloud itself. Has anyone encountered a similar problem?

I have an iOS app that I also run on my Macbook Air M1. My app plays music and I use FaceTime for voice communication with users of my app. How do I stop FaceTime from cutting out the music on my app?

Beginning April 24 releasing on the App Store requires using Xcode 16, iOS 18 SDK. https://developer.apple.com/news/upcoming-requirements/?id=02212025a Xcode only offers simulators for iOS 15. I had not been able to install and use previous versions. Does it imply iOS 15 is the minimum target allowed?

It seems that Xcode gets confused when there is another format specifier before a plural variable. As shown in the screenshot, %#@VARIABLE@ %f works fine, but an error occurs with %f %#@VARIABLE@.

Xcode 16.2 archive fails to compile XIB Xcode Archive command fails most of the time while compiling an XIB which was created in older Xcode. XIB was updated in Xcode 16.2 version also which did not fix this issue. Archive from Xcode app works but Xcode build command fails and no reason shown by the command. ** ARCHIVE FAILED ** The following build commands failed: CompileXIB /Users…/Resources/Nibs/<XIB_NAME>.xib

After update to Xcode 16.3, any breakpoints stopped in simulator and device. The scheme is configured to Debug in Build Configurator.

We have a macOS application packaged as a .pkg file.

Upgrading to Xcode 16.3, all previews across my AppKit project stopped working. The error message I'm getting is especially baffling. It says the project could not be built with incremental compilation because SWIFT_COMPILATION_MODE is set to "incremental": I tried clearing DerivedData with no effect. When I click the diagnostics button the information given is not very revealing, at least not to me. If I open the project in Xcode 16.2 everything works perfectly again. I switched over to Previews for all new code but this error situation is quite demotivating. Does anyone have any suggestions?

Hello. I'm seeing an inconsistent behavior where breakpoints I set in my (Swift) iOS app behave normally when I'm debugging on a device or on a simulator running iOS 17.x, but when I try using simulators of iOS 16 or 15 the breakpoints get ignored completely. I also observe that the breakpoints remain solid blue and do NOT adopt the dotted blue outline, as experienced by other users. I've seen a few posts on here and on SO about the general issue of ignored breakpoints (with no conclusive answer AFAIK), but I haven't seen any where the behavior varies with the SDK being used. The behavior is repeatable and predictable (within the same app at least). I am not adding the breakpoints after building/running, and I'm sure the logic reaches the lines with the breakpoints (and again, whenever I switch to an iOS 17 simulator, execution does pause as expected with the exact same breakpoints). Things I've tried and looked into: Clean up project build folder Delete and re-install simulators (iOS 16.4 and 15.5) Deleted the entire derived data directory, as well as the CoreSimulator one. Confirm the build configuration is Debug, and the "Debug executable" option is checked. inspect various build flags mentioned in other posts: {Swift compiler - Code generation - Optimization level - Debug: -0none; Debug information format: DWARF (I also tried DWARF with dSYM with no impact)}. Most of my settings are on the plain vanilla/out of the box side, with only a couple of SPM dependencies, and I've been maintaining the same app for about 5 years and don't think I've come across this behavior before. Currently using Xcode 15.1. Deployment target is 14.0. Thank you.

Hi, I recently updated to Xcode 16. Since then I successfully built my app and sent an update to the App Store. But suddenly, after an exception I've experienced while working on my code, the app is crashing on launch, without showing the stack trace, and showing only one warning in the console: warning: (arm64) /Users/myuser/Library/Developer/Xcode/DerivedData/myapp-bglvscamatwthwbfqmtzmbvxeewc/Build/Products/Debug-iphonesimulator/myapp.app/MyApp empty dSYM file detected, dSYM was created with an executable with no debug info. Tried deleting derived data Erasing all simulator data Reseting my computer No change yet. Any idea what am I missing? Thank you..

I have a framework project that uses third-party packages integrated via Swift Package Manager. The framework is then bundled as an XCFramework to support both simulator and device builds. However, when this XCFramework is consumed in a different version of Xcode than the one it was originally built with, it results in Swift compiler errors. For example, compiling the framework in Xcode 15.4 and then using it in a consumer app built with Xcode 16.2 results in Swift compiler errors(and vice-versa) Swift should work across different Xcode versions due to ABI stability. It appears the issue is originating from the referenced library, CryptoSwift. I’ve attached two projects: the [framework] project and the consumer app. https://bit.ly/4iWgi9i I’d really appreciate any help in identifying a solution to this problem.

I have an iOS app, and I am trying to add a companion WatchOS app. My iOS app depends on 2 libraries: GoogleMobileAds FirebaseAnalyticsWithoutAdIdSupport When I add a new target for WatchOS, the preview build starts to fail. I am not adding any libraries to WatchOS. The Google Ads and Firebase Analytics libs are only under the iOS target. I am unable to run the preview, I get an error when trying to build the watch scheme. The preview does not work. The build just crashes. I've included the error log below. But, here are the steps I've tried so far: Delete folders inside Derived Data Run a clean build (Cmd + Option + Shift + K) Delete scheme and create a new one Reset Package Cache Restart Xcode Restart Macbook But, it just does not work. I do not understand why the watchOS target is erroring for "GoogleUserMessagingPlatform" and "GoogleMobileAdsTarget" when those packages are not linked/used for the watchOS.

Hello! I've been trying to select a custom font to use for my label, but when I import it correctly, it doesn't show up in the fonts available for selection (See images below.) I've tried closing/reopening Xcode and cleaning and rebuilding the project. Nothing I've tried has worked so far. Thank you!
