Is there any way to build iOS 15 apps with Xcode 12.x?

Question

I'm using MacBook Pro mid 12. When I try to install Xcode 13 I can't do it. Apple says you need to use macOS 11 but my computer doesn't support it.

Now I need to update my app to iOS 15. Is there any way to create iOS 15 apps with Xcode 12?

Answer 1

I found a way. A man whose name is Ben S*** shares a patch on GitHub. This patch has helped upgrade my MacBook pro mid 2012 to Big Sur OS from MacOS Catalina.

After the upgrade, I could install XCode 13 and build my app based on iOS 15.
