Hi , I am currently encountering issues while running a Titanium application using Xcode 16. I would like to request your guidance on resolving the following problems: When running the Titanium app on a real device, I receive the following warning in Xcode and the app does not proceed beyond this point and the app is crashing on launch. warning: (arm64) /Users/Library/Developer/Xcode/DerivedData/Procedures-hamsarmfbtnowbcdocpmydtuafnp/Build/Products/Debug-iphoneos/Procedures.app/Procedures empty dSYM file detected, dSYM was created with an executable with no debug info. Thank you

PLATFORM AND VERSION Development environment: Xcode 16.4 (16F6), macOS 15.5 (24F74) Run-time configuration: iOS 18.3.1 DESCRIPTION OF PROBLEM I cannot build my app due to a module not found error when I'm importing Sample-Swift.h header to an ObjectiveC file. I need to use Swift code to ObjectiveC file with Swift code using an external XCFramework. It seems to be related to a mix with ObjectiveC and Swift code when Swift code uses class inheritance from FZWorkoutKit class. With a full Swift project, no issue. STEPS TO REPRODUCE Project https://fizzup.s3.amazonaws.com/files/public/Sample-WK.zip Open the provided project and try to build it. The issue occurs. In MyObject.m file, if you comment the first import (Sample-Swift.h), no issue occurs but I cannot use my Swift code (MyFile class). Uncomment the line commented in step 1. Go to MyFile.swift and change class inheritance from GoModeController (from FZWorkoutKit framework) to UIView (from UIKit). No issue occurs.

Hi guys, recently I've been investigating new UI Testing in Xcode7. There seems to be limited APIs we can call direct in UI test. Can I include header files and call public API of my tested app in UI Test? so that I can have more flexibility to set my app status before running test. I intent to call API method "-(void)reloadURL:(NSURL *)url" of my app in UI Test, but test failed with "XCTRunner -[_XCTRunnerAppDelegate myAppDelegateUtils]: unrecoginzed selector sent to instance 0x7cf0a992fe10"In Unit Test we can call any API of the tested app, does it support in UI Testing too? I'm a start learner of Xcode and its testing...could anyone help to answer this question? Thanks!

Hi all, I’m running into a persistent build issue with my Swift project ORSOFINAL after migrating from Xcode stable to Xcode-beta.app 26 (June 2025 version). ⸻ 💥 Errors displayed: 1. C99 was enabled in PCH file but is currently disabled 2. module file .../ModuleCache.noindex/SwiftShims-AXUM98L131W4...pcm cannot be loaded due to a configuration mismatch with the current compilation 3. missing required module 'SwiftShims' ⸻ 🛠 What I’ve already tried: • xcode-select -s /Applications/Xcode-beta.app/Contents/Developer • Deleted ~/Library/Developer/Xcode/DerivedData, ModuleCache.noindex, Archives, and Products • Ran sudo xcodebuild -runFirstLaunch • Clean Build Folder in Xcode-beta • Verified Command Line Tools setting points to Xcode-beta ⸻ ❓Looking for guidance on: • Whether this is a known bug in Xcode-beta • If SwiftShims/PCM conflicts are expected between versions • Best practices to safely migrate from Xcode stable to beta for Swift-based projects Any advice is much appreciated. Thanks, Mathéo

In 2020 I created FB7719215, which I updated several times (including just now) and in 2021 I created FB9204092, but the issue is still there: when I keep Xcode open (currently version 16.3), my battery drains much quicker, even when it's apparently idle. For instance, today I barely did anything in Xcode, but still it has been at a constant 90% CPU for the last hours, and I keep checking the battery percentage to check how much time I have left. Does anyone at Apple has an explanation, workaround and/or fix?

I am on MacOs 15.4.1 which is being deployed with an old version of Ruby ruby 2.6.10 and bundler version 1.17.2. I ran pod install after generating the pods with these versions and during the application compilation there have been several issues reported against pods code.

Hello! I am writing UI tests for an app with OAuth authentication and want to avoid the login screen. I want each developer to store the password and username locally on their machines. The bash script will get the token. I need to access that token from my test target somehow. The idea was to write them to a temporary file that git ignores and access this file from the bundle. But I can't add the file from the build script to the target and make it accessible from the code.

If you need help investigating a crash, please include a crash report in your post. To smooth things along, follow these guidelines: For information on how to get a crash report, see Acquiring crash reports and diagnostic logs. Include the whole crash report as a text attachment (click the paperclip icon and then choose Add File). This avoids clogging up the timeline while also preserving the wealth of information in the crash report. If you’re not able to post your crash report as an attachment, see Can’t Post Crash Report as Attachment below. If you want to highlight a section of the report, include it in the main body of your post. Put the snippet in a code block so that it renders nicely. To create a code block, add a delimiter line containing triple backquotes before and after the block, or just click the Code Block button. If possible, post an Apple crash report. Third-party crash reporters are often missing critical information and have general reliability problems (for an explanation as to why, see Implementing Your Own Crash Reporter). Symbolicate your crash report before posting it. For information on how to do this, see Adding identifiable symbol names to a crash report. If you need to redact the crash report, do so consistently. Imagine you’re building the WaffleVarnish app whose bundle ID is com.example.wafflevarnish but you want to keep your new waffle varnishing technology secret. Replace WaffleVarnish with WwwwwwVvvvvvv and com.example.wafflevarnish with com.eeeeeee.wwwwwwvvvvvvv. This keeps the text in the crash report aligned while making it possible to distinguish the human-readible name of the app (WaffleVarnish) from the bundle ID (com.example.wafflevarnish). Finally, for information on how to use a crash report to debug your own problems, see Diagnosing issues using crash reports and device logs. Can’t Post Crash Report as Attachment Crash reports have two common extensions: .crash and .ips. If you have an .ips file, please post that [1]. DevForums lets you attach a .crash file but not an .ips file (r. 117468172). To work around this, change the extension to .txt. If DevForums complains that your crash report “contains sensitive language”, leave it out of your initial post and attach it to a reply. That often avoids this roadblock. If you still can’t post your crash report, upload it to a file sharing service and include the URL in your post. Post the URL in the clear, per tip 14 in Quinn’s Top Ten DevForums Tips. Getting a Crash Report from the Xcode Organiser The Xcode organiser shows crash reports from customers. If you’re investigating such a crash and want to post a crash report: Navigate to the crash in the Xcode organiser. Note If you can’t see the right crash, check the filter popups at the top. In the list of crashes, secondary click on your crash and choose Show in Finder. That reveals the Xcode crashpoint document (.xccrashpoint) in the Finder. Secondary click on that and choose Show Package Contents. In the resulting Finder window, find a crash report (.crash) that accurately represents the crash you’re investigating and attach that to your forums post. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" [1] Because it’s easy to go from an .ips file to a .crash file. I usually do this by choosing File > Quick Look in the Finder. For more info about these file formats, see this post. Revision History: 2025-08-29 Added the Getting a Crash Report from the Xcode Organiser section. 2024-11-21 Added a recommendation to post the .ips format if possible. 2024-05-21 Added some advice regarding the “contains sensitive language” message. 2023-10-25 Added the Can’t Post Crash Report as Attachment section. Made other minor editorial changes. 2021-08-26 First posted.

HiSuppose i made a macOS App and want to connect to Oracle or mySQL Database I heard best way is using JSON which i dontknow anything about it, where can I find good reading about it thats specifically related to macOS or iOS Apps ?--Kindest Regards

I have this build error with Xcode 26 beta 2: var asset:AVURLAsset? func loadAsset() { let assetURL = URL.documentsDirectory .appendingPathComponent("sample.mov") asset = AVURLAsset(url: assetURL, options: [AVURLAssetPreferPreciseDurationAndTimingKey: true]) /*Error: Type of expression is ambiguous without a type annotation */ if let result = try? await asset?.load(.tracks, .isPlayable, .isComposable) { } } Is there an issue with try? in the new Swift compiler? Error: Type of expression is ambiguous without a type annotation

As far as I know, there was a time that you can capture GPU workload for opengles game app on iOS using Xcode. However, currently I'm using Xcode version 15.2 and iOS18，it seems the "capture GPU workload" button is always disabled when I'm trying to debug my game app which is using opengles api for graphics rendering no matter switchinng "GPU Frame Capture" to "OpenGL ES" or "Metal" or "Automatically" in the scheme. And I'm not able to capture GPU workload for my game on iOS. The only way to make the "capture GPU workload" button enabled is creating a new project using metal api for graphics rendering. But I don't want to change the graphics API, because it will cause a lot. Does Xcode still support capturing GPU workload for OpenGLES game app on iOS? If not, is there an alternative way?

Maybe it's just me but I can't find the attribute inspector anywhere. I have clicked, searched and tried everything I can think of. I love the new Xcode, but this has me dumbfounded.

Hello, FWIW I've been developing enterprise iOS apps going on 10 years and haven't seen a bug like this. It's a major blocker. Any advice is welcome. Pulled latest from my team's repository . I ran into a build issue. Reinstalled cocoa pods, resolved swift packages, cleared cache, and then tried to update my iOS simulators... Since then, everything is bricked.

When upgrading to a new version of Xcode, normally we look in the "Toolchain version history" table of the Xcode wikipedia page. But for Xcode 16.2, it lists git tag swift-6.0.3-RELEASE, which fails to compile with a known error. There was a fix for this error way back on July 4, 2024, but for some reason this fix does not appear in swift-6.0.3-RELEASE (as confirmed with git log, even though the tag occurred on December 2, 2024). So it turns out the minimum tag is swift-6.1-RELEASE for building LLVM with Xcode 16.2 (there are no other release tags between these two). Is it possible that the wikipedia table is simply incorrect in this case? If not, is there a workaround to build swift-6.0.3-RELEASE using Xcode 16.2, as published by Apple?

The crash log is located at ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log.
