Reply to Numbers Extension in Shortcuts
Since you're asking about how to use Shortcuts with built-in system applications, you're best off asking about that in the Apple Support Community. The Apple Developer Forums are for questions about APIs and features intended specifically for developers, such as if you were trying to build your own app and have some of its functionality available for use by customers in the Shortcuts app.

Reply to Xcode 16 warning about missing symbols of static framework
Hi @DTS Engineer , I am also facing this weird issue I am consistently encountering a build warning in Xcode 26 that prevents proper symbolication of crash logs. The warning states: warning: (arm64) /Users/mickey/Library/Developer/Xcode/DerivedData/CalendarSync-bjuvwxojzofqzzcmzzpdozbujrge/Build/Products/Debug-iphoneos/CalendarSync.app/CalendarSync empty dSYM file detected, dSYM was created with an executable with no debug info. Steps to Reproduce: Open the project in Xcode 26. Build the project for a physical iOS device (arm64) or Archive the project. The warning appears during the Generate dSYM phase of the build process. Troubleshooting Steps Already Taken (Issue Persists): Set 'Enable Debug Dylib Support' to No. Verified 'Debug Information Format' is set to 'DWARF with dSYM File'. Verified 'Generate Debug Symbols' is set to Yes. Set 'Strip Debug Symbols During Copy' and 'Strip Linked Product' to No. Performed 'Clean Build Folder' and manually deleted the Derive

Reply to Is it a bug in UIActivityViewController to Airdrop ?
I filed a bug report with an sample project and 2 files for testing. I confirm the problem. FB22253128 Here the message in FB (with the zipped sample project and 2 test files): Context: Xcode 26.3, iOS 18.7.6 on iPhone Xs In this iOS app, I call UIActivityViewController to let user Airdrop files from the app. When trying to send a URL whose file name contains some characters like accentuated (-, é, '), the transfer fails. Removing those characters makes it work without problem. Steps to reproduce Build and load the app on iPhone transfer the 2 pdf files ('name accentué.pdf' and 'name plain.pdf' to the Documents folder of Test app (I did it in Finder on Mac with iPhone USB connected to the Mac). The 2 files are identical except their name. Run the app Tap 'Send by AirDrop name plain.pdf' and select AirDrop to Mac : Transfer OK Tap 'Send by AirDrop name accentué.pdf' and select AirDrop to Mac : Transfer fails

Reply to Reliable region monitoring (geofence-based) while app is killed
The app will indeed be relaunched using Region Monitoring even if force quit. Reliability problems usually occur if the region around the station is not suitably set. There are a number of reasons, and some misplaced expectations on how region monitoring works that could be causing this: the region could not be placed correctly. A common issue is to use coordinates from a map or obtained otherwise. As region monitoring is based on WiFi and mobile signals, and those are affected by attenuation and reflections, as far as region monitoring goes, exact coordinates from a map may not be in the correct position. So, if you are having an issue with a certain location, you may want to double check that you see yourself located at the correct place and get the center coordinates according to live location rather than using a map or otherwise obtained coordinates. the region could be too small. Depending on the environment, the minimum radius could vary between 100 to 500 meters (and sometimes more, in rural areas). If

Notarization Requests In Progress
Hello, I am following up on several notarization requests in order to understand the process better. I submitted my first notary request yesterday and it took several hours to complete (where I submitted two other requests along the way thinking they may be stuck). They were all accepted after ~3 hours had passed since the first request was made. In that time I discovered a bug and had to rebuild/codesign, and submitted to notarize again. I've now had two requests with the new build (.zip file) in progress for ~18 hours. The bug fix I made between builds was innocuous and I'm wondering if my jobs are getting flagged due to recent account lockouts when I was first setting up my organizations' developer account. I've seen several replies here in the forum from DTS Engineers - hi Quinn :), so I'm aware of the possibility of 'rare' in-depth analysis, however I've experienced it in 100% of my requests. What is causing my requests to always require in-depth analysis and is there anything I can do

Reply to macOS Tahoe 26.4 Beta 4: Rosetta deprecation warning not shown — bug or intended behavior?
I like galad87’s take on this. Rather than worrying about other folks’ apps, I suggest that you on your own products. And in that case the messaging is super clear: If your build system or final software depends on Rosetta, you should be working to break that dependency as a matter of priority. And if you have technical questions about how to do that, please post them here on the forums. We’re hear to help.

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 App

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.

Unable to Download Apps via TestFlight - "The requested app is not available or doesn't exist" Error
Hi everyone I recently build an app and deployed it through app store connect and testet it on TestFlight. Everything worked fine up until build 1.0.3. Since then I have not been able to install the app on my phone through TestFlight - even though build and submission runs through successfully on eas, expo and app store. I have tried deleting and reinstalling the TestFlight from my phone. removing and adding back myself as tester. checking logs and commits from the shift from build 1.0.3 to build 1.0.4. I can see I changed name and slug, so I tried removing the app from app store connect and added a new one with new build and submission. Ran through successfully but still could not install the app through TestFlight on my iPhone. I have also tried reaching out to Apple Developer Support, but I have not heard from them. Has anyone tried something similar?

Can I use metal shader if I use RealityKit to build a VisionOS app?
I asked AI to build a realistic ocean shader for a VisionOS project using RealityKit. It gave a bunch instructions and asked me to connect large amount of nodes for the ShaderGraph in the Reality Composer Pro. I am just wondering if AI can help to generate the Metal shader code directly, or build the ShaderGraph nodes for me automatically.

Reply to Build stuck in "In Review" for 29+ hours after 3.1.2(c) resubmission
Our app Miiro (App ID: 6759159052) was rejected for Guideline 3.1.2(c) on March 13. What is Guideline 3.1.2(c) about? Nobody remembers all those numbers and corresponding meanings in heart. The build moved to In Review shortly after but has been stuck there for over 29 hours with no status change. So what's the issue? You don't have to wait for your turn because you pay a subscription fee?
