Since some weeks we have app crashes but I'm unabled to reproduce it. Does someone have an idea how this can happen and where to look?

Your app received a request to open a URL, so you should audit your code in that area and test those paths. For example, what happens in your app delegate when it receives a URL, such as through application:openURL:options:?

Thanx for the reply. In our AppDelegate there is no openUrl method implemented. We have some calls like this in some classes

Code Block UIApplication.shared.openURL(url)

I was wondering if some Objective-C code is involved in this because the stack trace contains squared brackets

Code Block [UIApplication _applicationOpenURLAction:payload:origin:]

Or is this irrelevant? We are using some libraries written in Objective-C

I figured out where the crashes are coming from: Smart Banner in SFSafariViewController.

When the app presents a SFSafariViewController and the smart banner of the app itself is shown in the html and the user taps on it then the app quits with the stack strack from above.

I'm glad to hear you figured out a reproducible test case.

Code Block
[UIApplication _applicationOpenURLAction:payload:origin:]

Or is this irrelevant? We are using some libraries written in Objective-C

It's relevant only in that the call is in the system UIKit library, which uses Objective-C. You should implement the delegate method I mentioned previously, and then work to understand how to handle the URL you're getting from your reproducible test case.
