Hi everyone, I’m an iOS developer working on a Mac with limited storage (256 GB). I’ve noticed that the ~/Library/Developer folder is taking up almost 90 GB, mainly due to Xcode-related content. Inside it I see folders like: Xcode/DerivedData DocumentationCache iOS DeviceSupport UserData CoreSimulator/Devices Before deleting anything, I’d like to understand which of these folders are safe to clean up, and what the potential side effects might be (for example, rebuild times, simulator re-downloads, etc.). What is the recommended best practice to manage disk space when using Xcode on a low-storage machine? Thanks in advance for your help.

Hello. I am attempting to wrap the C library libnfc as a Swift library. This is not for use on macOS - it's mainly for use on Linux (Raspberry Pi). I have a USB reader and my code appears to work so far, however the code/test/debug cycle is suboptimal if I'm running the code on the Pi. As I use a Mac for day-to-day coding, I'd prefer to use Xcode and my Mac for development. MacOS appears to capture the NFC hardware for its own frameworks and attempting to open a connection to the USB device gives a Unable to claim USB interface (Permission denied) error. ioreg shows that the hardware is claimed by an Apple framework: UsbExclusiveOwner = pid 10946, com.apple.ifdbun Is there a way to temporarily over-ride that system and use the hardware myself? I've tried Googling but most of the replies are out of date and Claude's advice launchctl unload /System/Library/LaunchDaemons/com.apple.ifdreader.plist doesn't appear to work... I'm wary of disabling SIP - is there a simple way to have access to the hardware m

I started using Xcode to package and submit my app yesterday, but it failed. I received a prompt Your app must be registered with App Store Connect before it can be uploaded. Xcode will create an app record with the following properties. halfway through the process. After filling it out and submitting, I received another prompt App Record Creation Error，App Record Creation failed as you do not have permission to perform requests of this type.。 I have already listed several apps on the app store. For the other apps, I also tried creating new versions, packaging, and submitting them, but I encountered the same error

Hello everyone, I have an app that is used in the education sector for high stakes assessment testing. I reviewed a lot of the WWDC2025 information in June, however, it seems we missed something critical in the What's new in UIKIt presentation. That would be the deprecation of UIRequiresFullScreen. We currently use this in our app and have been using it since iOS/iPad OS 9 when our app was written. The deprecation of this property has caused some major issues in our layout. Keep in mind we are a hybrid app so our mobile app is self-hosting a fullscreen version of WKWebView under the hood. This is common across assessment developers in the education sector. I removed the property and went through the migration guide (https://developer.apple.com/documentation/technotes/tn3192-migrating-your-app-from-the-deprecated-uirequiresfullscreen-key) and it doesn't appear to be straight forward on how to lock the orientation in landscape. I tried several different approaches: Requesting the screen orientation lock we had

Environment Device: iPhone 15 Pro iOS: iOS 18.0 Framework: AVFoundation App type: Custom camera app using AVCaptureSession + AVCaptureVideoPreviewLayer I’m seeing an intermittent but frequent issue where the camera preview layer briefly flashes empty after certain interruptions, even though the capture session reports itself as running and no errors are emitted. This happens most often after: Locking and unlocking the device Switching cameras (back ↔ front) The issue is not 100% reproducible, but occurs often enough to be noticeable in normal usage. What happens The preview layer briefly flashes as empty (sometimes just a “micro-frame”) Duration: typically ~0.5–2 seconds before frames resume session.isRunning == true throughout No crash, no runtime error, no interruption end failure Focus/exposure restore correctly once frames resume Visually it looks like the preview layer loses frames temporarily, even though the session appears healthy. Repro Intermittent but frequent after: Lock → unlock device Switching

I noticed that when the render command encoder adds no draw calls an apps memory usage seems to grow unboundedly. Using a super simple MTKView-based drawing with the following delegate (code at end). If I add the simplest of draw calls, e.g., a single vertex, the app's memory usage is normal, around 100-ish MBs. I am attaching a couple screenshot, one from Xcode and one from Instruments. What's going on here? Is this an illegal program? If yes, why does it not crash, such as if the encode or command buffer weren't ended. Or is there some race condition at play here due to the lack of draws? class Renderer: NSObject, MTKViewDelegate { var device: MTLDevice var commandQueue: MTL4CommandQueue var commandBuffer: MTL4CommandBuffer var allocator: MTL4CommandAllocator override init() { guard let d = MTLCreateSystemDefaultDevice(), let queue = d.makeMTL4CommandQueue(), let cmdBuffer = d.makeCommandBuffer(), let alloc = d.makeCommandAllocator() else { fatalError(unable to create metal 4 objects) } self.device

Hi Apple Team, We have high crash counts in App Store Connect > App Analytics > Crashes (197), but zero matching crashes in Xcode Organizer or Firebase Crashlytics for the same app version/build. App details: Bundle ID: com.youtunein.youtunein Version: [1.88,1.89,1.90,1.91] Affected iOS versions: [1.88,1.89,1.90,1.91] Steps tried: Downloaded raw .crash files from App Store Connect and symbolicated in Xcode Organizer – no crashes appear. Firebase console clean, no spikes. dSYM files uploaded via Xcode Archive/Transporter. Enabled crash reporting in app (no custom crash handling blocking). Crash reports attached (top 3 symbolicated). No ANRs/symbolication issues visible. Production + TestFlight both affected? Need help understanding discrepancy and resolving. Thanks!
