CLLocationManagerDelegate not working on Siri Intents
I need to elicit the location of the user in the Siri intents and so I call: override init(){ super.init() self.locationManager=CLLocationManager() self.locationManager.delegate = self; self.locationManager.startUpdatingLocation() self.locationManager.requestWhenInUseAuthorization() } Still neither public func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) nor public func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) are ever called, notwithstanding the presence of the correct entry in the info.plist, the inclusion of the library and the indication of the delegation with: class IntentHandler: INExtension, INSendMessageIntentHandling, CLLocationManagerDelegate, UISceneDelegate are ever called. Is there any problem with CLLocation manager on intents? What would be a big problem as there is no way to share information with the main app!

XcodeKit module not found, but why?
I'm working on a plugin, and that target works just fine. I made another target so I can test some computation functions. It doesn't need much from XcodeKit, just some of the structures. I added XcodeKit and Cocoa, but the import XcodeKit just says "no such module". If I switch to the plugin target, it's just fine. I've compared both schemes, but I don't see difference which would affect finding the framework.

Significant Performance Regression in Apple Clang 16 for Assembly File Processing
I've observed a significant performance regression in Apple Clang 16 (Xcode 16.0/16.2) compared to Clang 15 (Xcode 15.2) when processing flutter aot compilation. Further research shows that clang -cc1as process became extremely slow. The compilation time has increased by approximately 4x.

Custom font not support in Xcode 16.3
I'm experiencing an issue with a custom font not loading properly in Xcode 16.3. The font files are included in the bundle, listed in Info.plist, and verified for correct names using UIFont.familyNames, but they still don't appear at runtime. Has anyone else run into this with Xcode 16.3? Could this be related to recent changes in asset packaging or font catalogs?

Simulator frozen while Xcode debugger attached
I'm on Xcode 16.3 (16E140), using iPhone 16 Pro Simulator with iOS 18.4, on macOS Sequoia 15.4. Today is the first time using this particular configuration. On Friday I was using Xcode 16.2, simulator on 17.5, macOS 15.3.2. This morning while running the app in the debugger I get times where I pause in using the app, perhaps to look up some information or make some notes, then go back to the simulator and nothing works. It is just frozen. Tap tap tap all day long and nothing responds. In the Xcode console I get this over and over while the simulator doesn't respond. nw_protocol_socket_set_no_wake_from_sleep [C100.1.1:2] setsockopt SO_NOWAKEFROMSLEEP failed [22: Invalid argument] nw_protocol_socket_set_no_wake_from_sleep setsockopt SO_NOWAKEFROMSLEEP failed [22: Invalid argument] I then hit the "Stop" button in Xcode debugger and get this in console <0x10843a0b0> Gesture: System gesture gate timed out. XPC connection interrupted Message from debugger: Xcode has killed the LLDB RPC server to allow the debugger to detach from your process. You may need to manually terminate your process. The Simulator springs to life immediately. It even seems to have queued up my most recent inputs and happily accepts them and processes them as normal.

Unity (IL2CPP) iOS Build: "_placeGeoAnchor" Undefined Symbol for Architecture arm64
Hi all, I’m running into a persistent linker error when building my Unity 6 project (IL2CPP, iOS target) that calls a Swift method via an Objective-C++ wrapper. Despite following all known steps, I keep getting: Undefined symbols for architecture arm64: "_placeGeoAnchor", referenced from: _GeoAnchorTrigger_placeGeoAnchor in libGameAssembly.a ... ld: symbol(s) not found for architecture arm64 I’m trying to place a persistent AR anchor at real-world GPS coordinates (so that the same asset can appear at the same location for a returning user). Since I’m targeting iOS, I can’t use Google’s geospatial anchors (but I sooo wish I could--please apple I beg of you stop being so selfish lol). I've already done these things: Swift file is added to Unity-iPhone target. .mm and .h files are in Unity-iPhone target under Compile Sources. Bridging header is set to Unity-iPhone-Bridging-Header.h. Generated header name is correct (GeoTest-Swift.h). Build Active Architecture Only set to No. Function has attribute((visibility("default"))). Unity project uses IL2CPP scripting backend. Yet I'm still getting the same linker error — it appears Unity (via IL2CPP) references the function, but Xcode doesn't link it. It’s something small that’s being missed with how IL2CPP links native symbols? Or maybe I need to explicitly include something in Link Binary With Libraries? I’ve verified symbol visibility and targets repeatedly. I’ve built AR features in Unity before (for Quest), but this is my first time trying to bridge C# → Objective-C++ → Swift in this way for a geolocation-based AR anchor for an iphone. I'm going crazy, I’ve been stuck on this for 12+ hours now, so any insight or nudge would be deeply appreciated. SPECS: Macbook Pro M4 Pro--Sequoia 15.4 Unity 6000.0.45f1 IPhone 11 iOS 18.4 Xcode 15

Cannot run apps that use the callAsyncJavaScript() method on older simulators
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. The specific error is dyld[89984]: Symbol not found: _$sSo9WKWebViewC6WebKitE19callAsyncJavaScript_9arguments2inAF17completionHandlerySS_SDySSypGSo11WKFrameInfoCSgSo14WKContentWorldCys6ResultOyyps5Error_pGcSgtF Referenced from: <82CC68A8-9426-343E-82CD-5443F53A6919> /Users/dave/Library/Developer/CoreSimulator/Devices/69CE58A3-8162-4616-B110-5857E6E2889F/data/Containers/Bundle/Application/3F27AAA0-8E96-437D-A1F4-DECD2E1A95B5/CallAsyncJavascript.app/CallAsyncJavascript.debug.dylib Expected in: <E11EC0F5-2AD1-3402-AB03-31A85EA6EB3A> /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/WebKit.framework/WebKit

Previews stopped working in Xcode 16.3 with baffling error message
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?

Xcode debugger doesn't pause on breakpoints (simulator SDK < iOS 17)
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.

Cannot run apps that use the callAsyncJavaScript() method on older simulators
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. The specific error is dyld[89984]: Symbol not found: _$sSo9WKWebViewC6WebKitE19callAsyncJavaScript_9arguments2inAF17completionHandlerySS_SDySSypGSo11WKFrameInfoCSgSo14WKContentWorldCys6ResultOyyps5Error_pGcSgtF Referenced from: <82CC68A8-9426-343E-82CD-5443F53A6919> /Users/dave/Library/Developer/CoreSimulator/Devices/69CE58A3-8162-4616-B110-5857E6E2889F/data/Containers/Bundle/Application/3F27AAA0-8E96-437D-A1F4-DECD2E1A95B5/CallAsyncJavascript.app/CallAsyncJavascript.debug.dylib Expected in: <E11EC0F5-2AD1-3402-AB03-31A85EA6EB3A> /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/WebKit.framework/WebKit

What is the minimum iOS deployment target after April 24 2025?
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?

Xcode 16.3, an error is occurring in the String Catalog.
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@.

Previews stopped working in Xcode 16.3 with baffling error message
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?

Xcode debugger doesn't pause on breakpoints (simulator SDK < iOS 17)
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.
