Reply to Can I move Xcode files to an external SSD safely?
Don't use the comment feature here in the forums. It's hides your response. Unfortunately, a 256 GB with Xcode is going to be a significant challenge. I've had problems with my 1 TB drive. One of the more problematic issues with Xcode are all the iOS simulator runtimes. Perhaps you could try to delete all of those except one. Or perhaps you could look into a cloud server. Sometimes those have small drives too. If you only need it for a couple of days, AWS might be more cost effective than a monthly fee.

Apple Pay In-App Provisioning – Apple server failure when adding a card
We are implementing Apple Pay In-App Provisioning in our issuer iOS application and are encountering a HTTP 500 error returned from Apple servers during the provisioning flow. The issue occurs after generating the encrypted payload and attempting to complete the provisioning process. The Apple service responds with 500 Internal Server Error, preventing the card from being added to Wallet. We would appreciate assistance identifying whether this is caused by: • a payload formatting issue, • cryptographic material mismatch, • entitlement / configuration issue, • or a server-side issue. Environment Platform • iOS: 26.3.1 • Device: iPhone 13 mini • Xcode: 26.3.1 Apple Pay configuration • In-App Provisioning entitlement enabled • Issuer app authorized by Apple for provisioning • Payment Network: Mastercard • Token Service Provider (TSP): MDES Testing environment • Production • App distribution method: TestFlight Provisioning Flow Overview Our implementation follows the standard Apple Pay In-App Provisionin

Reply to Can I move Xcode files to an external SSD safely?
First up, make sure your external drive is formatted as APFS (or HFS Plus). If you do a lot of Mac-specific stuff on, say, FAT32, you will eventually run into weird problems. Second, there are a number of things you can definitely move to an external drive: Xcode itself The three items (Derived Data, Archives, Compilation Cache) listed in Xcode > Settings > Locations. After that things start to get more complex. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to how to inhibit -fprofile-instr-generate passed to linker
It is caused by code coverage being injected by test plan that is autogenerated in scheme. Disabling code coverage for driver target and deleting test scheme will fix the problem. However, you might want to have testing with your project. But it looks like any test plan inside same project will inject profile-instr-generate. Not sure how to have testing for main app, and no code coverage flag injected for driver. Seems like bug in Xcode.

Static library links on device but fails on iOS Simulator
I’m working on an iOS workspace with: a static library project: M800SDK a test app project: TestAppObj I was able to build M800SDK for iOS Simulator on Apple Silicon as a simulator static library, and I also verified the architectures in the produced .a file. However, when I link the app target against that simulator build and try to build TestAppObj for iOS Simulator, I get the following linker errors: Undefined symbols for architecture arm64: _OBJC_CLASS_$_TokenMngr clang++: error: linker command failed with exit code 1 Additional context: The library links and works correctly when building the app for a physical iPhone. And the public header TokenMngr.h is found correctly by the app target. The app target is compiled as Objective-C++ where needed. The library is linked in the app target under “Link Binary With Libraries”. Could you help me understand: Is it possible to run on iOS Simulator ? the recommended way to package and consume this library for iOS Simulator on Apple Silicon? Also I am aware i can al

Reply to How to monitor heart rate in background without affecting Activity Rings?
Hi @Ziqiao Chen and everyone, Thank you @simonfromhelix for reviving this thread. @Ziqiao Chen — I tested the frontmost app state approach as you suggested.

Building a 4-agent autonomous coding pipeline on Apple Silicon — MLX backend questions
Hi, I'm building ANF (Autonomous Native Forge) — a cloud-free, 4-agent autonomous software production pipeline running on local hardware with local LLM inference. No middleware, pure Node.js native. Currently running on NVIDIA Blackwell GB10 with vLLM + DeepSeek-R1-32B. Now porting to Apple Silicon. Three technical questions: How production-ready is mlx-lm's OpenAI-compatible API server for long context generation (32K tokens)? What's the recommended approach for KV Cache management with Unified Memory architecture — any specific flags or configurations for M4 Ultra? MLX vs GGUF (llama.cpp) for a multi-agent pipeline where 4 agents call the inference endpoint concurrently — which handles parallel requests better on Apple Silicon? GitHub: github.com/trgysvc/AutonomousNativeForge Any guidance appreciated.

Instruments Malfunction
I’m reporting a severe reproducible issue in Instruments, specifically when using the SwiftUI instrument and opening Show Cause & Effect Graph. What happens: • Instruments becomes extremely laggy/unresponsive • The graph/detail area can turn solid magenta/pink • Memory usage rapidly increases (I observed around 18 GB, 25 GB, and up to 34 GB) • My Mac has crashed/restarted during this, or in other terms, had a kernel panic, where my Mac froze, and everything unresponsive. The Trackpad wouldn't even click. Important detail: • I could not find a generated kernel panic log after the crash/restart. Repro context: • SwiftUI iOS app profiled from Xcode • Trigger is specifically entering Show Cause & Effect Graph • Recordings can be short and still trigger it • Issue is much less severe or absent if I avoid that view What I already tried: • Rebooting • Short captures / fewer instruments • Clearing Xcode/Instruments caches/preferences • Retesting after cleanup • Reinstalling Xcode Is

Feedback Assistant Unresponsive
Hello, I was told from Developer engineers to post an Xcode issue on Feedback Assistant. It has been 6 weeks and I have yet to receive a single reply or acknowledgement on my feedback post. I would just like to at least get some sort of acknowledgement from Feedback Assistant that my post is being tracked or if a resolution is in work please. Here's the post: https://feedbackassistant.apple.com/feedback/21824703

Reply to Waiting for review?
Hello, thanks you for your response, and noted. Yes, I did explain. My frustration is that the App is designed specifically for iPhone devices, and I thought I had selected the correct settings in Xcode, by removing all options other than iPhone. However, the reviewer tested the app on iPad, in compatibility mode, and as such, there was a display issue. I have now made the relevant telemetry adjustment to the info.plist file, in the hope that it can't be confused and used on an iPad in compatibility mode. My frustration has been that the expectations from what I have read suggest 24-48 hour review time, and my app is so simple, (1 page, 4 actions), no connectivity or database etc required. Thank you for your response though, it's all a bit new to me. Fingers crossed!

Reply to .storeButton(.visible, for: .policies) shows “Terms of Service Unavailable” — how does it work?
Same query here. I've tried everything I can think of to get the terms link to render content based on App Store Connect configuration. I can only get it working in local development in Xcode builds by passing a dedicated url to the supposedly custom terms link field, which, according to both common sense and official developer documentation, isn't necessary. I've set the policy link there, which works, but the terms link never renders the proper content, despite having opted into the standard EULA.

Reply to Can I move Xcode files to an external SSD safely?
The only parts of Xcode that can't be moved to external storage are the parts that take up the bulk of your storage. You haven't said anything about your storage (internal or external) or your development needs, so I can't provide any more detailed information. In some cases, you can reduce Xcode's storage. You may be able to remove some or all of the simulator runtimes. Generally speaking, this is one of those cases where you have to weight the cost of your time and trouble against the cost of a computer with more internal storage.

Can I move Xcode files to an external SSD safely?
Hi everyone, I’m running out of space on my Mac and I need to use an external SSD to free up room, especially because Xcode is taking a lot of storage. I want to know if it’s safe to move some Xcode files—projects, derived data, or system-related files—to an external SSD. Which files can I move safely, and which should stay on the internal drive? I want to avoid breaking anything or causing issues with Xcode or macOS. Also, is it the same situation if I use an external HDD instead of an SSD? Are there additional risks or performance issues to consider?
