Still happens with official release 26.1

Have the same issue. Made a swizzling class to get the exact view which crashes: - (void)swizzled_addSubview:(UIView *)view { if (view == self) { NSLog(@"🚨 ERROR: Tried to add self (%@) as subview to self. This is illegal and causes a crash.", self); NSLog(@"Backtrace:\n%@", [NSThread callStackSymbols]); //For debugging return here return; } [self swizzled_addSubview:view]; } Which gives a hint which view: UIView+Swizzling.m | 🚨 ERROR: Tried to add self (<_TtCC5UIKit32_UITabBarVisualProvider_FloatingP33_3C6E5A7AE2316B749C88F887559DAAB619SelectedContentView: 0x12cc8c000; frame = (0 0; 360 62); autoresize = W+H; layer = <CALayer: 0x12cc528e0>>) as subview to self. This is illegal and causes a crash. By returning that function if view == self it does not crash any more but has side effects e.g. icon color is black instead of blue in my case... And probably some more. I think there is nothing we could do than waiting for a fix.

Hi, i have the same issue, even when the app is running in foreground. According the documentation it should always call: - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler { It's working with iOS 15.1 but not with latest 15.2 Beta 3 (and probably also not with Beta 2). The console logs say: dasd Submitted Activity: com.apple.pushLaunch.com.copany.appid:F51673 at priority 5 <private> dasd Adding a launch request (<private>) for application <private> by activity <private> dasd Launch requests for <private>: <private> dasd Daemon Canceling Activities: {( com.apple.pushLaunch.com.copany.appid:7BCCA4 )} dasd CANCELED: com.apple.pushLaunch.com.copany.appid:7BCCA4 at priority 5 <private>! dasd Removing a launch request for application <private> by activity <private> SpringBoard cancelActivities: 1 activities were not found: <private> dasd com.apple.pushLaunch.com.copany.appid:F51673:[ {name: ApplicationPolicy, policyWeight: 50.000, response: {Decision: Absolutely Must Not Proceed, Score: 0.00, Rationale: [{[pushDisallowed]: Required:1.00, Observed:0.00},]}} ], FinalDecision: Absolutely Must Not Proceed} I am aware that the system might cancel starting the app in background but with the app running in foreground it should always call the method in AppDelegate. Any hints are welcome...
