Why is Xcode taking forever to install/launch app?
Ever since Xcode 15 and iOS 17 came out development has quite often been a nightmare of waiting and waiting -Xcode displaying endless circles saying preparing the device, connecting to the device, installing the device. But recently to add to this, installation and launching is just taking really forever. I'm currently running Xcode 15.1 and various versions of iOS 17 (I have several phones) and installing the app from Xcode takes about 7 - 10 minutes (compared to the same app installing in seconds with Xcode 14 for example). Then once its finally installed, it then takes further minutes to launch, Xcode often actually displays a dialog saying its taking longer than expected to launch the app, adding the footnote LLDB is likely reading from device memory to resolve symbols. What could be reasons, and solutions, for the excruciatingly slow installation time, and launch time? I really need to find a solution to this please - making a code change tweak, running, making another, running

Reply to Announcing the Swift Student Challenge 2026
Framework compatibility: My app uses Foundation Models and Apple Pencil. The app runs great through Xcode; however, due to Apple Pencil support, it has to be run on a physical device. However, Swift Playgrounds on iPad doesn't support iOS 26. I was just wondering if this is something that can be mentioned in submission notes. eg. The app needs to be compiled in Xcode but run on a physical device.” Or should we expect iPadOS 26 support for Swift Playgrounds by the time of submission? Thank you!

Developer Program Membership Still Pending After Successful Payment (Turkey Region)
Hello , I need some help regarding my Apple Developer Program enrollment. I purchased the Developer Program on December 3rd, 2025 at 16:03 (Turkey time). The payment was successfully processed by my bank, and I also received the official Apple Store receipt email confirming the purchase. However, my Developer account still shows: • “Purchase your membership” • “Your purchase may take up to 48 hours to process.” • Enrollment status: Pending • App Store Connect still not accessible It has now been more than 5 days, and the enrollment has not been activated. Here are the details: • Region: Turkey • Payment amount: 1029 TRY (local pricing for the Developer Program) • Payment status: Completed / Posted (not pending) • Case ID with Apple Support: 102769533427 • I have already opened a support case, but there has been no resolution yet. I would appreciate any guidance from others who experienced similar issues. Is this a known delay for Turkey-based accounts, or does it usually require manual activation by

Reply to C function in library code gets stripped when distributed
Here is a more step by step breakdown of the problem I have a iOS library that exposes a C function. This function is marked with default visibility and used via attribute tags to prevent the compiler/linker from stripping it #ifdef __cplusplus #define DYLIB_EXPORT extern C __attribute__((visibility(default))) __attribute__((used)) #else #define DYLIB_EXPORT __attribute__((visibility(default))) __attribute__((used)) #endif DYLIB_EXPORT bool say_hello_world(); #import helper_functions.h #import bool say_hello_world() { NSLog(@Hello WORLD 🟢!); return true; } From a dynamic library, called sdk, I want to call this function. In this example it's a Rust lib unsafe extern C { fn say_hello_world() -> bool; } #[unsafe(no_mangle)] extern C fn sdk_init() -> i32 { unsafe { say_hello_world(); } return 0; } When the app is compiled and launched from Xcode (either on debug or release schemes) then this works, the following snippet works and prints the hello WORLD message: #import OpacityObjCWrapper.h #import helper

CIRAWFilter.outputImage first-time cost is huge (~3s), subsequent calls are ~3ms. Any official way to pre-initialize RAW pipeline (without taking a real photo)?
Hi Apple Developer Forums, I’m developing an iOS camera app that processes RAW captures using Core Image. I’m seeing a large “first use” performance penalty specifically when creating the CIImage from CIRAWFilter.outputImage. What’s slow (important detail) I’m measuring the time for: let rawFilter = CIRAWFilter(imageData: rawData, identifierHint: hint) let ciImage = rawFilter.outputImage This is not CIContext.render(...) / createCGImage(...). It’s just the time to access outputImage (i.e., building the Core Image graph / RAW pipeline setup). Observed behavior First time accessing CIRAWFilter.outputImage: ~3 seconds Second time (same app session, similar RAW): ~3 milliseconds So something heavy is happening only on first use (decoder initialization, pipeline setup, shader/library compilation, caching, etc.). Using Metal System Trace, I also noticed that during the slow first call there are many “Create MTLLibrary” events, while the second call doesn’t show this pattern. Warm-up attempts using bundled

App Clip Advanced Experiences don't get published
We have an app with a few App Clip Advanced Experiences. Since around 28th of August the status of the experiences seems to be stuck in either CREATE_SUBMITTED or UPDATE_SUBMITTED and they don't get updated to PUBLISHED anymore. I found this in the experiences JSON loaded by AppStoreConnect when editing the experiences: statuses: { doc_count_error_upper_bound: 0, sum_other_doc_count: 0, buckets: [ { key: PUBLISHED, doc_count: 182 }, { key: CREATE_SUBMITTED, doc_count: 7 }, { key: UPDATE_SUBMITTED, doc_count: 3 } ] }, This shows that 10 experiences are stuck in other status than PUBLISHED. I created a Feedback with ID FB15041208 and a DTS last week. This is REALLY important for us to be fixed immediately since we have customers that rely on this!

SpeechAnalyzer error "asset not found after attempted download" for certain languages
I am trying to use the new SpeechAnalyzer framework in my Mac app, and am running into an issue for some languages. When I call AssetInstallationRequest.downloadAndInstall() for some languages, it throws an error: Error Domain=SFSpeechErrorDomain Code=1 transcription.ar asset not found after attempted download. The .ar appears to be the language code, which in this case was Arabic. When I call AssetInventory.status(forModules:) before attempting the download, it is giving me a status of downloading (perhaps from an earlier attempt?). If this language was completely unsupported, I would expect it to return a status of unsupported, so I'm not sure what's going on here. For other languages (Polish, for example) SpeechTranscriber.supportedLocale(equivalentTo:) is returning nil, so that seems like a clearly unsupported language. But I can't tell if the languages I'm trying, like Arabic, are supported and something is going wrong, or if this error represents something I can work around. Here's the relevant

Reply to XCode26 - Unable to launch Image in storyboard for landscape picture in Portrait orientation
The LaunchViewController removed and all orientations added on the general tab. any other settings? Your screenshot only shows the checkbox areas for the orientations. The section on the General tab for the Launch screen is scrolled out of view. You want it to look identical to the configuration you'd get if you selected File > New Project, so you can use that to compare the values you have set. Further, I can't see the contents of the Info tab, where you'd set the keys for UILaunchScreen. — Ed Ford,  DTS Engineer

Reply to Degraded RoomPlan performance
@Vision Pro Engineer Thanks for the reply, Michael Is the following based off what you've heard or do you have videos and files that show the behavior? Mostly based off user testimonial. I think we have recorded a couple instances of this during onboarding sessions, but in those cases, we suspected that screen sharing itself could be contributing to the issue. Do you have any logging in place that is capturing any RoomCaptureSession.CaptureError errors in production? Yes - we track all fatal scanning errors. We haven't noticed an uptick in those. It seems like another developer was able to improve performance by resolving a memory leak. Have you profiled the application when performing multiple scans in a row? We have done some profiling over the years, but it's difficult because the act of profiling itself severely degrades scanning performance. We have noticed that RoomPlan itself seems to cache/retain resources after scanning even if we have no active references to it. I believe we reproduced this
