Issue with Dynamic Links with Xcode 13

[crleonard]

There seems to be an issue with FirebaseDynamicLinks when running on Xcode 13.

Call FirebaseApp.configure() from app delegate, when /FIRDLJavaScriptExecutor.m is hit, the line [_wkWebView loadHTMLString:htmlContent baseURL:nil]; causes a crash with the result of Thread 1: EXC_BAD_ACCESS (code=1, address=0x10).

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hey @crleonard, sorry for the troubles. It looks like this is similar to #7618 - can you please share which version of Firebase you're using, update to the latest if you're not on it, and let us know if it's resolved?

Hey @crleonard. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[morganchen12]

@lammertw can you try reproing the crash with some memory debugging tools enabled (and also fully symbolicate the crash log)? It's not normal for WebKit to crash in class_createInstance.

[lammertw]

@morganchen12 I have no idea why but after switching some branches, turning on and off memory debugging tools and then running it without, now it's no longer crashing (without any actual changes in my git repo). So if the problem does return I'll let you know.

[crleonard]

I'm still having the same issue. Do you have any updates?
