WKWebView
I am using Xcode 15.2. I am loading a URL in a WKWebView, but a hand cursor appears above the web view. Scrolling up and down does not work. I tried adjusting the scroll bounds and isUserInteractionEnabled, but the hand cursor is still visible. How can I fix this?

App crashing on real iPhone only (working fine on simulator and Xcode preview)
Hi, I'm currently facing an issue where my React Native app crashes only on a real iPhone. On the simulator and in Xcode preview, the app runs fine. Previously, I had an issue with FlatList regarding props.getItem, which I solved by installing some missing Babel dependencies. After that, everything worked correctly in the simulator. But when I try to open the app on a real device, it shows the splash screen and crashes immediately. I've already done a full clean and reset, including: npx react-native start --reset-cache Deleted node_modules and Pods, reinstalled everything Cleaned build folder via Xcode Deleted DerivedData Restarted Metro bundler and simulator/device The issue only happens on the physical device. Here’s a portion of the crash log IDate/Time: 2025-04-14 19:11:28.6796 -0300 Launch Time: 2025-04-14 19:11:28.5292 -0300 OS Version: iPhone OS 18.3.2 (22D82) Release Type: User Baseband Version: 4.20.03 Report Version: 104 Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: SIGNAL 6 Abort trap: 6 Terminating Process: JazminChebar [1973] Triggered by Thread: 0 Last Exception Backtrace: 0 CoreFoundation 0x19a0865fc __exceptionPreprocess + 164 (NSException.m:249) 1 libobjc.A.dylib 0x197601244 objc_exception_throw + 88 (objc-exception.mm:356) 2 JazminChebar 0x1009b2c04 RCTFatal + 568 (RCTAssert.m:147) 3 JazminChebar 0x1009c81f8 __28-[RCTCxxBridge handleError:]_block_invoke + 532 (RCTCxxBridge.mm:1178) 4 libdispatch.dylib 0x1a1e19248 _dispatch_call_block_and_release + 32 (init.c:1549) 5 libdispatch.dylib 0x1a1e1afa8 _dispatch_client_callout + 20 (object.m:576) 6 libdispatch.dylib 0x1a1e29a34 _dispatch_main_queue_drain + 984 (queue.c:8093) 7 libdispatch.dylib 0x1a1e2964c _dispatch_main_queue_callback_4CF + 44 (queue.c:8253) 8 CoreFoundation 0x19a0d2bcc CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE + 16 (CFRunLoop.c:1793) 9 CoreFoundation 0x19a0cf1c0 __CFRunLoopRun + 1996 (CFRunLoop.c:3163) 10 CoreFoundation 0x19a121284 CFRunLoopRunSpecific + 588 (CFRunLoop.c:3434) 11 GraphicsServices 0x1e73914c0 GSEventRunModal + 164 (GSEvent.c:2196) 12 UIKitCore 0x19cc6a674 -[UIApplication _run] + 816 (UIApplication.m:3846) 13 UIKitCore 0x19c890e88 UIApplicationMain + 340 (UIApplication.m:5503) 14 JazminChebar 0x100178708 main + 80 (main.m:7) 15 dyld 0x1c037dde8 start + 2724 (dyldMain.cpp:1338)

Xcode 16.3 Compile fails
After updating to 16.3, my project now fails to compile with the diagnostic: "Command SwiftCompile failed with a nonzero exit code". This is a SwiftUI document project with two local packages, the second of which is a rather large one with 112 SwiftUI files. It is this second package that is failing. There are no issues when compiling with 16.2. Without diagnostics I'm having a bit of difficulty in determining the cause. My thought is to regress the commits unit 16.3 gives a success, or shows issues. Although I'm not catching a similar issue in the forums, I'm seeing other problems with 16.3. Has anyone else had such build failure isolated to 16.3? Any advice on other ways to approach this problem? Thanks in advance

Flutter Xcode Errors
I just started working with Flutter. I use a Macbook m2 and my phone is an iPhone XR. I made a very simple application but no matter what I did, I couldn't start my application on my iPhone XR. I got help from all the AIs but we couldn't do it. I deleted everything including Xcode, Android Studio and Flutter and reinstalled them and I followed the SDK installation step by step on the Flutter page but I can't run my project on Xcode. I entered my Apple account including all the signings and certificates via the .workspace file extension but it didn't work. The error I get from Xcode keeps changing. We installed podfiles with the support I got from the AIs and after some fiddling, I got the only error right now: Command PhaseScriptExecution failed with a nonzero exit code

How to run XCode 15.2 on Sequoia?
Hi, I have a project that is based on a GPL library. The GPL library has some issue since early 2024 that requires it to be run on XCode 15.2. Any XCode above 15.2 will only give you "Invalid MinimumOSVersion." and "Missing Info.plist value." errors. So I installed 15.2 again. But now I have another problem because it can only run on Ventura. How do I run XCode 15.2 on my Sequoia MacOS? I hate to reinstall the OS all again. Thank you.

CoreBluetooth Scan not working when OS upgraded to 18.3.1
Hi, I currently have an app that connect to an arduno via CoreBluetooth. However, the app no longer discovers the arduino when the operating system was upgraded to iOS 18.3.1, however on iOS version 17.6.1 the ardiuno was discoverable I was able to test this theory on two different phones each with different iOS versions. I see that it is failing to find the peripheral at the scan however the logs indicate that the central state is powered on. Why are my peripherals no longer being discovered with this update? and what is the solution?

Any way to automate adding libraries in Xcode from Swift Package Manager (SPM)?
Hi all, I’m looking for a way to automate the process of adding Swift Package dependencies (SPM) into an Xcode project. Right now, I’m doing this manually via: Xcode → Project → Swift Packages → Add Package Dependency... But I’d like to script this step — ideally as part of a CI/CD pipeline or a setup script. I explored the xcodeproj Ruby gem, but it doesn’t support adding SPM packages, and there's no official support for editing the .xcodeproj structure related to Swift Packages. So my question is: Is there any Apple-supported or community-supported way to programmatically add Swift Package dependencies to an Xcode project or workspace? Would love to know if anyone has: Used xcodebuild, xcodegen, or other tools for this Explored editing project files directly (like project.pbxproj or Package.resolved) Found any API or CLI hooks from Apple for this Thanks in advance!

Xcode is is throwing error when I run my Unity Build
When I try to build my project in Xcode (from Unity AR) project, it throws me these errors: I feel like I've tried everything to make the LaunchScreen work. I downloaded xcode the night I tried running this build, so the whole deleting and redownloading and restarting everything didn't work. I've tried making sure my macbook and terminal are fully up to date. I literally can't find a solution! Please help!! I will also say, I'm fairly new to App building, Xcode, and Unity. But this does seem like a barrier that is stopping me from testing my project.

Trouble Translating a Second Word Using TranslationAPI
I’m developing an app to save words that users learn in a language they are studying. Here’s the basic workflow: Type a new word Add the new word Every time a word is added, it gets saved to a list that includes its meaning and the name of the language — useful when saving words in multiple languages Problem: For some reason, the “Add new word” button only works for the first word. The second word is not being added to the list. Here is my code: import SwiftUI import NaturalLanguage import Translation struct ContentView: View { @State private var inputWord: String = "" @State private var detectedLanguage: String? @State private var translationConfiguration: TranslationSession.Configuration? @StateObject private var viewModel = WordViewModel() var body: some View { VStack(spacing: 24) { // Input field TextField("Type a word in any language", text: $inputWord) .padding() .background(Color(.systemGray6)) .cornerRadius(10) // Button to translate and save Button("Add new word") { translateAndSave() } // .disabled(inputWord.trimmingCharacters(in: .whitespacesAndNewlines).isEmpty) .buttonStyle(.borderedProminent) // List of saved words Text("My Words") .font(.system(.title2)) List { ForEach(viewModel.words) { word in VStack(alignment: .leading, spacing: 4) { Text(word.inputWord) .font(.headline) Text(word.nativeTranslation) .font(.subheadline) .foregroundColor(.gray) Text(word.detectedLanguage.uppercased()) .font(.caption) .foregroundColor(.blue) } .padding(.vertical, 4) } } Spacer() } .padding() .animation(.easeInOut, value: detectedLanguage) // Automatically triggers translation when configuration changes .translationTask(translationConfiguration) { session in do { let response = try await session.translate(inputWord) viewModel.addWord( input: inputWord, native: response.targetText, detected: detectedLanguage ?? "Unknown" ) // Reset fields after saving inputWord = "" detectedLanguage = nil translationConfiguration = nil } catch { // Handle error print("Translation error: \(error.localizedDescription)") } } } // Function to detect language private func detectLanguage() { let recognizer = NLLanguageRecognizer() recognizer.processString(inputWord) if let code = recognizer.dominantLanguage?.rawValue { let name = Locale.current.localizedString(forIdentifier: code) detectedLanguage = name?.capitalized } else { detectedLanguage = "Unable to detect" } } // Function to prepare translation private func translateAndSave() { detectLanguage() translationConfiguration = TranslationSession.Configuration( source: nil, target: Locale.Language(identifier: "en") ) } } Question: Does anyone have any idea what I can do to fix this?

Swift, kevent, and wth?!?!?
I have this code: var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16((EV_ADD | EV_ENABLE)), fflags: 0, data: 0, udata: nil ) I looked at it and thought why do I have those extra parentheses? So I changed it to var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16(EV_ADD | EV_ENABLE), // changed line! fflags: 0, data: 0, udata: nil ) and then kevent gave me EBADF. Does this make sense to anyone?

Gathering Required Information for Troubleshooting Xcode Previews or Swift Previews Issues
Hi, You're here because your project has issues related to Xcode Previews or Swift Previews. The issue you're experiencing may be the result of any of the following: An error in your SwiftUI app, Xcode previews, or on-device previews. A configuration error in your Xcode project, including any third-party dependencies or packages. A system issue in the operating system, SwiftUI, or in Xcode Previews. Based on your request, I need more information about your SwiftUI app when rendering Xcode Previews or on-device previews. Specifically, I’ll need the diagnostics Swift Previews generates to make sure I understand the error encountered by the preview system. Please create a report in Feedback Assistant to share the details requested in the instructions below. For issues with macOS, Mac Catalyst, on-device iOS, or on-device visionOS previews, perform the following steps to gather diagnostics: Download and install the Swift Previews logging profile for your device. Reproduce the error while previewing on device, taking note of the timestamp when the error occurred. Attach the Previews diagnostics, sysdiagnose from your Mac, a sysdiagnose from the previewing iOS or visionOS device. For issues with Xcode Previews, perform the following steps to gather diagnostics: Download and install the Swift Previews logging profile for your device. Reproduce the error in Xcode Previews, if you haven’t already done so. If an error banner appears in the canvas, click the "Diagnostics" button within the banner, then go to Step 5; otherwise, continue to Step 4. If the error banner is missing, navigate to the menu in Xcode: Editor > Canvas > Diagnostics In the presented sheet, click the "Generate Report" button. Attach a zip file containing the diagnostic report to your bug report (it will be named something like previews-diagnostics-0123456789.zip). Submitting your feedback Before you submit to Feedback Assistant, please confirm the following information is included in your feedback: with the Swift Previews logging profile installed, attach the sysdiagnose logs gathered after reproducing the issue the Previews diagnostics generated by Xcode timestamp identifying when the issue was reproduced focused sample Xcode project that reproduces the issue (if applicable) screenshots or videos of the error (optional) Please include all requested information to prevent delays in my investigation. After your submission to Feedback Assistant is complete, please respond to your original Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your SwiftUI app, a configuration issue within your Xcode project, or an underlying issue in the operating system, SwiftUI, in Xcode Previews, or on-device previews. Cheers, Paris X Pinkney |  WWDR | DTS Engineer

WatchOS Xcode 16.4 to sample live RR intervals from the PPG sensor ERROR
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
