iOS 26.1 and newer breaks alternate icons in the simulator
Starting in iOS 26.1, attempting to set an alternate icon while running in the simulator fails and throws errors:
Failed request to update the app’s icon:
Error Domain=NSPOSIXErrorDomain Code=35 "Resource temporarily unavailable" UserInfo={_LSFile=LSIconAlertManager.m, LSLine=113, LSFunction=-[LSIconAlertManager iconChangeAlertTokenForIdentity:error:]}
I started noticing this in my own apps so I downloaded Apple's own test project for alternate icons. The error also produces there. Rolling back to iOS 26.0 or running on a physical device seems to get around the issue.
