Keith Harrison @useyourloaf.com · 26/06/2025that’s a good point, not sure it’s possible but would be nice to have as a fallback 010
Keith Harrison @useyourloaf.com · 26/06/2025Yes, I had the same problem, the WWDC video skips over what you’re supposed to do. In theory, the icon is backwards compatible so you only get the glass effect on iOS 26. In practice, seems there are some rendering issues on older versions. 110
Keith Harrison @useyourloaf.com · 26/06/2025I found a workaround to the problem with Icon Composer not working for alternate app icons.

Keith Harrison @useyourloaf.com · 26/06/2025Here's what worked for me in the end after comparing to what Xcode generates for app icons in the asset catalog. The iPad variant seems to be necessary for it to work there. Hopefully Apple fixes Xcode in a future beta, 010
Keith Harrison @useyourloaf.com · 25/06/2025Thanks. One difference I can see is that I don't have the CFBundleAlternateIcons key listed in the Info.plist file. (I'm also using a SwiftUI app life-cycle but not sure that's relevant). Will play some more. Thanks again! 010
