@Etresoft The goal is to use older Asset Catalog based app icons for pre-26, and new Icon Composer based app icons for 26+.
With Xcode 26.0, you could make it work using the --enable-icon-stack-fallback-generation=disabled setting.
But as of Xcode 26.1, that setting is now being ignored and when the app is run, the Icon Composer based app icon is used for all versions, pre and post 26.
While this thread is about macOS, it equally applies to iOS apps. I'm sticking with Xcode 26.0 because I want my old app icons for iOS 18 and older. Xcode 26.1 is now preventing this from being possible.
