Thread 1:
I met the same problem.
It seems -[UIInputViewSet restorableResponder] returns a wild pointer. This property is neither weak nor strong.
I added a symbol breakpoint to -[UIInputViewSet restorableResponder] and -[UIInputViewSet setRestorableResponder:], the assembly code shows they have neither store_weak nor store_strong code.
I used a workaround, hook -[UIInputViewSet restorableResponder] and return nil. Maybe it will cause another problem. But after testing it seems work well.

I have a very bad issue right now:
Behavior:
Application work when debug, but in release exit when app start.
The debugg information is not clear for the reason the application fail only in release mode.

Fortunately the problem is Entitlement.plist, for some reason when use SecureStorage from Xamarin.Essentials, the application crash in release Testflight on shop, so I remove SecureStorage and problem solved.
Thanks all for all the answers.
Recently I got this error:
Failed to render and update auto layout status for YourViewController (GwR-7s-08s): The agent crashed
I've tried:
Editor > Refresh all views
Delete Derived Data
Delete and Undo my view controller
Restart My Pc
I'm really lost now.
This is what i found from console (~/Library/Logs/DiagnosticReports) IBDesignablesAgent-IOS.crash.

I have couple of crashes on startup of app and there are no code changes made since it was last installed by Xcode. When I open device logs, Xcode is not fully symbolicating crash, particularly the place where it crashed. Why is it so and how do I get the fully symbolicated crash log? The crash is unfortunately not reproducible in direct debugging session.

When I was debugging the iOS application, meet with some issue causing application to crash when playing video in fullscreen mode and this issue is concerned with the specific device iPhone 6s. The application works good in iPhone 6 and iPhone 5s without crash.

Recently I am trying to debug with the information provided by Crash Reports. So far I have been able to identify and fix some bugs but not this one.
As I read from the crash report, it's something wrong with UIDictationController, but my code did not call UIDictationController at all. The crash report is generated by PLCrashReporter.
It seems that the user is using an iPad Mini (WiFi) and running iOS 6.0.2.

Is there any way that I can do with this bug? Or, at least mitigating the issue? Thanks in advance.
the problem is that somewhere in your app you have a keyboard come up and with iOS version 6.0.1 and 6.0.2, apple enabled the dictation controller even if you didn't specify it to be enabled. Two solutions to fixing it: create a custom keyboard without it or implement dictation in your app.
My suggestion is to just let it be, only affects two outdate iOS versions and hopefully the crashes will go away as the users upgrade their devices
I have the keyboard coming up for a custom TextView, and when the user pushed the dictation button, said something, pushed finish, and then they tried to dismiss the keyboard, there would be a crash. Possible this is also what you're experiencing?
