Trying to upload an iOS26 app archive with Xcode 26 beta 7 and getting ITMS-90717: Invalid large app icon, meaning my app is not eligible for TestFlight testing.
My App contains an IconComposer .icon asset, so I'm not sure what it's complaining about. I'm not seeing anything in the release notes about this, and I'm not sure if I'm doing something wrong or not.

This appears to have something to do with the IconComposer .icon file containing png / rasterized layers that have transparency.
Making it a single layer .icon file with a single layer with a non-transparent PNG appears to have resolved the app store connect errors.
