The exports are for marketing purposes. You should not use the exported images as your app icon, but the .icon file itself you get by saving.

We're days away from the final release and this API is still unusable. Inside a sheet the corner radius is incorrect. Inside a view pushed in a NavigationStack there's no corner radius at all. No replies here, no answer to filed feedback. Just broken. Am I supposed to ship like this?

Filed as FB20992520. Normally CKSyncEngine registers for remote notifications silently without hitting the callback. It just does so when running UIApplication.shared.registerForRemoteNotifications() at the same time which seems to be unwanted behavior.
