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?

When testing Energy Impact on Xcode, it shows zero, and other data is normal

I've recently upgraded my project from Xcode 15 to Xcode 16. Without changing any build settings or compiler flags, I noticed that the final executable size has increased significantly when building the same C++ code. Investigation: To investigate further, I compared the Link Map outputs from both versions of Xcode. One key difference I found: The symbol size for std::sort increased from 4,336 bytes (Xcode 15) to 6,084 bytes (Xcode 16) – a ~40% increase. This seems to be part of a broader trend where other standard library symbols are also taking up more space in the binary when built with Xcode 16. Questions: Has Apple Clang or libc++ in Xcode 16 changed the implementation of STL algorithms like std::sort? Are there changes in inlining, template instantiation, or debug info that could explain the increase? Is this expected behavior? If so, is there any guidance on minimizing the binary size regression?

When renaming A.value, it also causes the value inside the conditional compilation in checkRename to be renamed. How to resolve or avoid this situation? class A { let value = "1" } class B { var value = 0 } func checkRename() { var b = B() #if os(iOS) b.value = 456 #elseif os(macOS) b.value = 789 #endif } Xcode Version 15.4 (15F31d).

Xcode 16.2. When calling openURL:options:completionHandler: when in the simulator for a link in the app store (for example: http://itunes.apple.com/us/app/slidewords/id503737864?mt=8) behavior is fine for simulated iPads, not for simulated iPhones. When the simulated device is an iPad, the call correctly opens the app store link. When the simulated device is an iPhone, an error message "Safari cannot open the page because the address is invalid." Note: the call works on an an actual iPhone (iPhone SE 3rd generation, unsure about other devices).

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. SchemeBuildError: Failed to build the scheme “timerWatch Watch App” While building for watchOS Simulator, no library for this platform was found in '/Users/k/Library/Developer/Xcode/DerivedData/timer-dhkdhvfcqtfgskfdxpmupujswtuh/SourcePackages/artifacts/swift-package-manager-google-user-messaging-platform/UserMessagingPlatform/UserMessagingPlatform.xcframework'.

I am using a Mac computer running macOS 15.5 with Xcode version 16.3 (16E140) and an iPhone XS Max on iOS 18.5. When debugging my app on the real device using Xcode, the app gets stuck on the launch screen and fails to proceed to the main interface. There is no output in the Xcode console, and the top of the window continuously shows "attaching to [app name] on [iPhone name]". Here are the details: The same issue occurred when the phone was running iOS 18.4.1. When I tested on another real device running iOS 17, the app launched and ran normally. I’ve tried clearing the cache, but it didn’t help. I deleted the ~/Library/Developer/Xcode/iOS DeviceSupport folder, let it re-download the necessary files, and ran the app again, but the issue persists. I’m currently out of ideas and would appreciate any assistance.

The “Deployment Targets” for iOS was IOS12 or higher in Xcode15, but is now listed as IOS15 or higher in Xcode16. https://aninterestingwebsite.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?

After developing the IOS app using XCode, I https://aninterestingwebsite.com/account/resources/identifiers/list Created Identifiers (HanBaoAI) and locally created Certificate SigningRequest.certSigningRequest https://aninterestingwebsite.com/account/resources/certificates/list Created Certificates (Expiry Date 2026/04/21) and also created profiles (HanBaoAI, Expires 2026/04/21), and then https://appstoreconnect.apple.com/apps I created an app (HanBaoAI) and uploaded it to the official website using Product Archive in xcode. The upload was successful, but the official website's testflight showed 1 (processing). When I refreshed the page, there was no information in testflight. May I ask what the reason is? How to solve it? Please provide complete and detailed solution steps.

My app uses the top navigation panel which contains the back button, a title, and prompt. On an actual device, the navigation area is light and shows all three items. On the simulator, the navigation area is black and only the back button is shown. I need this to be correct for app store screen shots.

After setting the title for the button and changing the font of the title, an inner margin appears on the button itself. How to remove this inner margin? It doesn't occur on the simulator, but this phenomenon exists on the 17.6 mobile phone.

At the last place I worked it took roughly 5 minutes to do an application build. Which in turn made doing any sort of TDD or ever just regular Unit Tests extremely painful to do as the cycle time was simply too long. But that got me thinking. In recent versions of Xcode, Apple added Previews for SwiftUI Views that basically showed code changes to the View in real time. And Previews were made possible by extremely targeted compilation of the view in question. So... what if instead of a Preview pane in the Xcode IDE there was a Test pane the could be displayed such that Tests for a piece of code could be created and run almost immediately? Perhaps by adding a #Testing section to your code #Testing(MyService.self) // Define the entity to be tested. If you could drop the turnaround time AND provide a test playground for service level code that could speed development of such code greatly... and encourage interactive test development at the same time. What do you think?

Hello, For one of my recent release (2 versions ago), I used to be able to check its p50 of Hang Rate, but now it disappear and not showing up in XCode Organizer Metrics anymore. The p90 of Hang Rate of this version is still there. It's so unpredictable. Is there something we can do to get this data to populate? If not, may I understand usually why this issue will happen, is it something frond-end bug or is it because there is some thing abnormal going on in the back-end data?

I know there has been issues with SFSpeechRecognizer in iOS 17+ inside the simulator. Running into issues with speech not being recognised inside the visionOS 2.4 simulator as well (likely because it borrows from iOS frameworks). Just wondering if anyone has any work arounds or advice for this simulator issue. I can't test on device because I don't have an Apple Vision Pro. Using Swift 6 on Xcode 16.3. Below are the console logs & the code that I am using.

I'm integrating Apple Pay with PayFort in a Swift iOS application, and I’m currently working on preparing a valid purchase request using Apple Pay, as described in PayFort’s documentation: 🔗 https://docsbeta.payfort.com/docs/api/build/index.html?shell#apple-pay-authorization-purchase-request The documentation outlines the following required parameters: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod apple_displayName apple_network apple_type Optional: apple_applicationData I understand these should be derived from the PKPayment object after Apple Pay authorization, but I’m having trouble mapping everything correctly. Here’s what I’m seeing in code: payment.token // Returns something like: <PKPaymentToken: 0x28080ae80; transactionIdentifier: "..."; paymentData: 3780 bytes> payment.token.paymentData // Contains 3780 bytes of encrypted data payment.token.paymentData.base64EncodedString() // Returns a long base64 string, which at first glance seems like it could be used for apple_data, // but PayFort doesn't accept it as-is — so this value appears to be incomplete or incorrectly formatted I can successfully retrieve the following values from payment.token.paymentMethod: apple_displayName apple_network apple_type However, I’m still unsure how to extract or build the following in the format accepted by PayFort: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod These may be contained within the paymentData JSON, but I’m not sure how to decode it or if Apple allows decrypting it in a way that matches PayFort’s expected format. How can I correctly extract or build apple_data, apple_signature, and apple_header from the Apple Pay token? Also, how should I handle the decryption or decoding (if necessary) of paymentData to retrieve values like apple_transactionId, apple_ephemeralPublicKey, and apple_publicKeyHash? If anyone has successfully set this up or has example code that bridges Apple Pay and PayFort’s expected request format, it would be super helpful! Thanks in advance 🙏

If I create an Xcode (version doesn't matter, 16.N )project of type framework then install some dependencies using SPM. Then within the Frameworks and Libraries section, the Embed part is empty. This doesn't happen if the project type is app rather than framework. If I want to set this to embed or not embed then how can this be done if its not even visible, for that matter how can I tell what it is set to even?

I have a project (that uses pre-compiled headers) that uses different compiler options for SOME files. For those files I have this is in my CMakelists.txt: if(CMAKE_C_COMPILER_ID MATCHES "GNU|Clang") set_source_files_properties(${AVX_Files} PROPERTIES COMPILE_OPTIONS "-mavx;-mavx2;-mfma;-mssse3;-msse4.2") set_source_files_properties(avx_simd_check.cpp PROPERTIES COMPILE_OPTIONS "-mxsave") endif() When I build for ARM, it all works :) When I try to build for X86_64, I get the following error for avx_simd_check.cpp: error: current translation unit is compiled with the target feature '+xsave' but the AST file was not 1 error generated. and for all the other files in question: error: current translation unit is compiled with the target feature '+avx' but the AST file was not error: current translation unit is compiled with the target feature '+avx2' but the AST file was not error: current translation unit is compiled with the target feature '+fma' but the AST file was not error: current translation unit is compiled with the target feature '+sse4.2' but the AST file was not error: current translation unit is compiled with the target feature '+ssse3' but the AST file was not 5 errors generated. How can I solve this please? David

Hi, I compiled Intel Open Image Denoise library for iOS, and obtained a bunch of dependent dylibs. I want to use these ones in a swift project (via bridging as this is C/C++) targeting the iPad. I understand that it is required to embed these dylibs into frameworks as iOS doesn't allow dylib. Is it necessary to generate one framework for each dylib? If so, how are dependencies between the libraries (and their frameworks) managed? Or, is it possible to generate only one framework embeding all the dependencies?

Hi, I am getting an error stating "Argument passed to call that takes no arguments". I want this Apple Watch App to measure and store RR Intervals from the PPG sensor on the Apple Watch for Heart Rate Variability calculations. Please help me fix this, I can't figure it out. Here is my code: heartbeatQuery = HKHeartbeatSeriesQuery(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async }) // End query data handler // --- END OF PROBLEMATIC INITIALIZER --- // Execute the query if it was created successfully It recommends the fix as removing this part: '(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async })' But after I remove that it says "Cannot assign value of type 'HKHeartbeatSeriesQuery.Type' to type 'HKHeartbeatSeriesQuery'" PLEASE HELP ME Thanks
