[_UISnapshotWindow actualSceneBounds]: unrecognized selector

Hi everyone,


Anyone else seeing crashes like this:


Fatal Exception: NSInvalidArgumentException. -[_UISnapshotWindow actualSceneBounds]: unrecognized selector sent to instance


Seems to be happening in low memory situations.


Any easy fix? Our app isn't using a huge amount of RAM.


Thanks

We've also just started seeing this crash in our app in the last week... the app seems to crash within a few seconds of starting up and usually after being backgrounded/foregrounded. Both crashes were on iPhone X devices running 12.0.1 or 12.1. Haven't been able to reproduce and there isn't a lot of references to the UISnapshotWindow class but probably related to the device capturing a screen shot of the app state when going into the background (if I had to guess).


The crash is being captured by BuddyBuild crash reporting but not the AppStore crash reporting.

I am seeing exactly this issue on all iOS 12 devices, 100% when in background. I use state preservation/restoration. I even filed this as a bug here https://bugreport.apple.com/web/?problemID=49255115

Seeing this crash often on iOS 12. Was there any response from Apple on that bugreport?

Issue still happended on iOS 13.1.3

Since iOS 13 I've seen a large number of app crashes with the error:


Crash, -[_UISnapshotWindow actualSceneBounds]: unrecognized selector sent to instance 0x10ea79be0


I wonder if it's the OS taking a snapshot of the app in it's last state for use in the App Switcher.

  • Hi AlertSenseGeek, I am getting the same stack trace. Did we find any solution for the above ? Please help.

I filed a report for iOS 13, https://feedbackassistant.apple.com/feedback/7469181 including a reference to your radar. Hopefully, Apple gets enough duplicates.

We've got the same crash and it is hard to replicated. It happened on ios 12.4.0 device with low memory available.
Any update here?

This has become our most common crash so I'm trying a workaround. My stack traces look similar and always seemed related to updating the snapshot of the keyboard due to a background fetch event. My intended solution is to resign first responder when going in to the background and restore it when coming back. I've never been able to reproduce the crash directly myself but I'll leave an update here in a couple weeks if that fixes it.

One relatively unique thing about our app is we throw up a privacy cover when transitioning to the background to avoid showing private information on the switcher. Is anyone else who's seeing this crash doing that? Ideally we could disable the screenshot-updating behavior altogether, because the static view isn't ever going to look any different, but I don't see a way to do that.

Update: resigning and restoring first responder did not resolve the issue (thought it does look much nicer with the privacy screen). Really desperate for a fix here.
Update: SOLVED IT!

We were accidentally doing navigation in the background, which was still happening when we called the completionHandler, which triggered a new snapshot, which crashes when navigation is in progress.

Solution:
inside application(_:, didReceiveRemoteNotification:, fetchCompletionHandler:), before doing any navigation, guard that case .inactive = application.applicationState, otherwise return. That worked for us!

@Burnsides were you able to reproduce applicationState == .background within didReceiveRemoteNotification? When would such a case occur? when it does occur should the navigation still happen?

Every time I try to reproduce, applicationState == .inactive.

Anybody got lucky with reproducing this issue?

We're experiencing this issue on ~5% of users, majority using iOS 15. App crashes on startup, but we're not sure if on cold start or getting back from background.

Looks like this might be some navigation issue. [UIViewController _setViewAppearState:isAnimating:] + 832 adds to it...
