It's maddening. I just opened a file and now it's gone because I had the audacity to open another file. I've learned that I can double click the tab of the first file to make it a permanent tab... but, of course, I'll need to do that every time I ever open any file ever, and if I close that file and come back to it later I'm going to be constantly having to double click tabs just to make Xcode stop replacing my tabs for me. It's nuts. It's driving me insane. Please. Is there any way to just DISABLE the temporary tabs behavior? I don't find it helpful in any way and I find it to be destructive to my development workflows.

Hello, I am encountering "unable to open dependencies file" error in XCode that started after updating to Xcode version 16.2 and macOS version 15.2. The error message I receive is as follows: error: unable to open dependencies file (/Users/user/Library/Developer/Xcode/DerivedData/MyProject-cwpcmnebzjpgkzcuoauxlaeiqrsg/Build/Intermediates.noindex/MyProject.build/Debug-iphoneos/MyProject.build/Objects-normal/arm64/MyProject-master.d) (in target 'MyProject' from project 'MyProject') This problem didn’t occur with XCode 16.1; the project was building successfully before the update. Now, even reverting to XCode 16.1 doesn’t resolve the issue anymore. Here’s what I’ve tried so far without success: Switched the compilation mode to “Whole Module” Cleaned the build folder Cleared Derived Data Thank you in advance for any suggestions!

I am not able to use the Debug Memory Graph tool as well as Leaks instrument inside Xcode to debug my project. I'm running my project on physical iOS device on running 18.3 version and I tested the project on two different MacBooks running Xcode 16.3 and 16.1. On both the same problem persists. I have also reinstalled the project on the device and tried restarting all devices and cleared DerivedData. Nothing helped.

Is there a way to use CFBundleVersion instead of CI_BUILD_NUMBER from XCode Cloud's workflow on Web ? We would like to have control over the major and minor version numbers of the build from the workflow.

I added a new liquid glass icon built with Icon Composer to my app. It works and looks great on iOS 26 but Xcode complains that required icon files for older versions are missing. I still have the old AppIcon in my Asset Catalog but it seems like it's not being used. How do I configure Xcode to use the old icons for iOS 18 and the new icon for iOS 26?

I can't find Rosetta Simulators in Xcode 26 Beta, even when I select "Show all destinations."

SwiftUI preview hangs on "Preparing iPhone Simulator for Previews". Also simulator hangs when trying to build and run. This occurred after I installed iOS 17 simulator. I tried reverting back to an iOS 16 version of the simulator, but haven't figured out how to do that. Build and run to an iPhone device works fine. Any ideas would be appreciated. Thanks.

My question set is fairly broad, but I can't seem to find any answers anywhere. As a fairly low-level developer, the vast majority of my work is done with Sublime Text, terminal-based compilers, IDEs like Coq's (coq.inria.fr), and code that has to be compiled by terminal. These projects are at the very fabric of what I do, and I fear that Rosetta 2 will be inadequate until LLVM and other systems are updated to run natively on Apple Silicon. Honestly, I can't really afford complex virtualization systems like Parallels or VMWare (not that they help much) and I'd rather not give up MacOS for my Ubuntu desktop. I was raised on MacOS and I can't imagine losing features like scenes or seamless integration with the rest of my electronics. I want to keep my initial post fairly simple and broad, but if anyone has any questions on what I need supported, feel free to ask. I am sure I'm not alone here.

When creating an icon using icon composer, I cant upload a build to testflight/App Store connect. Running on device from Xcode works fine, but as soon as I archive and upload to App Store Connect, I get an error saying the icon contains an alpha channel

Hi, I'm testing out Xcode 16 beta and I have a couple of questions: Is Swift Assist only available on Sequoia? I see that predictive code completion is per https://www.apple.com/newsroom/2024/06/apple-empowers-developers-and-fuels-innovation-with-new-tools-and-resources/, but I tried the beta on Sonoma and I'm not seeing it Regarding Swift Assist - I understand that code is only used to process requests and never stored on servers, and Apple will not use it to train machine learning models. However, my company's security team may still decide that using Swift Assist is too much of a risk. How can we disable it across multiple developer machines? Thank you!
