Sporadic crashes due to ([UIColor systemBackgroundColor]: unrecognized selector sent to class - Fatal Exception: NSInvalidArgumentException) about swift-sdk HOT 8 CLOSED

Will it be possible for you to get symbolicated crash reports? It is hard to understand the stack trace here. Also, more importantly can you please report which iOS version is causing this crash.

We have the following code using systemBackgroundColor. This should not cause any crash since we are doing an OS version check.

            if #available(iOS 13, *) {
                view.backgroundColor = UIColor.systemBackground
            } else {
                view.backgroundColor = UIColor.white
            }

from swift-sdk.

We see the crashes in 13.x.x and above, here's the full list.

50% iOS 13.6.8
25% iOS 13.6.7
24% iOS 13.5.1
1% iOS 13.3.1
1% iOS 13.2.1
1% iOS 13.0.1
1% iOS 13.3.0
1% iOS 13.1.1

I don't have anything more than what I have posted above. The code that you shared makes sense, if that's the case we should not see any crashes regarding [UIColor systemBackgroundColor].

Are you seeing this crash in iOS 14.x devices? I think this problem is occurring due to some iOS bug. This can probably be fixed by changing the code to the following. If we make this change will you be able to test it and confirm if the fix worked?

            if #available(iOS 14, *) {
                view.backgroundColor = UIColor.systemBackground
            } else {
                view.backgroundColor = UIColor.white
            }

So far we are only seeing the crash in iOS 13.x devices ( based on data from Firebase - Crashliytics). If you can make the change we can update the Iterable SDK and include in the next version.

Since we can not reproduce the issue locally we won't be able to verify the fix immediately however once we release the next version of our application I can check the crash and leave a message here

Appreciate the fast response.

We would release a new version within a couple of weeks at most.
