Xcode15 on Sequoia

Recently I upgraded to Sequoia only to find out that I can‘t run Xcode 15 anymore: I used to run it directly by opening up the app contents and run xcode binary from the macos folder. But this trick is not working anymore (xcode is killed before launch). I need xcode15 to continue working with a project that I have based in Unreal 5.3. I tried to migrate my project to xcode16 but I have thousands of compiler issues that will be hard to fix (with xcode15 everything was ok). does anyone know how to continue using xcode15 and not forcing us to waste time migraring to xcode16? thank you in advance

What are those compiler issues? There is very little difference between Xcode 15 and Xcode 16. It shouldn't cause that kind of problem.

Plus, Apple now requires Xcode 16 and building against the current SDKs for submission to the App Store. So unless you are distributing this project through some other means, then you have no choice.

Otherwise, you can always install a VM, or roll back to an earlier OS version.

Thank you for your response. I will try again and paste the compiler errors here, maybe I am doing something wrong.

I downloaded Unreal 5.4 and rework all the issues that I got there. It wasn't a smooth path but finally got working on Xcode 16.3. The majority of issues came from a source code plugin that uses deprecated classes.

Anyway, @etresoft, your answer is accurate. Thank you so much.
