HW kbd Failed to set (null) as keyboard focus ios

In my iOS app crash log I found this statement:
HW kbd Failed to set (null) as keyboard focus ios
Does anyone know what is this and how to resolve it?
I've just encountered this exception running a Xamarin app on the simulator. It started occurring after I toggled the software keyboard off while debugging the app. Given the exception mentioning the keyboard I think that's what caused it.
Uninstalling the app from the emulator, cleaning and rebuilding fixed the issue for me.
Unsure if this bug is on Apple's side or Xamarin's.
The only references I could find related to Xamarin was close, but the inverse of this - the app crashing on the simulator, but working on an actual device. The resolution in that forum post doesn't describe what the problem might be, but does suggest that cleaning the project and rebuilding may resolve it.
The specific message HW kbd Failed to set (null) as keyboard focus ios is related to the app crashing, but there's no additional information in the pastebin to really help pin down why it's crashing.
You might also consider adding logging statements in your code to see if you can isolate the issue.

App crashes on iPad device but working on simulator

I just have device UDID & client reported that the app is crashing
on his device & he is not able to start application.
The client device iOS version is 7.1.2
Also i am not having any crash report.(Asked for Crash Report)
Now referring
(iAd works on simulator but crash on device(ipad)):
I am assuming the reason behind this might be the library,
So will making iAD.framwork optional & handling codes related to this do the trick?
**Update:
Unfortunately the cause of the crash was -[__NSCFString containsString:]: unrecognized selector sent which was iOS version fault & not device fault. I got it resolved. sorry to iAd for blaming or trying to blame. Long live iAd. Thanks**
First of all - you need crash details. Without it, nobody help you.
Integrate any crash reporter SDK: Crashlytics or anything like this.

Crittercism SDK 4.3.7 is crashing in iOS 8.0 device

Crittercism SDK 4.3.7 is crashing in iOS 8.0 :
Getting error at com.apple.NSURLConnectionLoader after running application.
Can anybody have solution for this or need to wait for new version of SDK with fix for this bug.
Let's try doing this and see where it takes us.
Set NSZombieEnabled, MallocStackLogging, and guard malloc in the debugger. Then, when your App crashes, type this in the gdb console:
(gdb) info malloc-history 0x543216
Replace 0x543216 with the address of the object that caused the crash, and you will get a much more useful stack trace and it should help you pinpoint the exact line in your code that is causing the problem.
More can be read here: "Thread 6 com.apple.NSURLConnectionLoader: Program received signal: EXC_BAD_ACCESS"
FYI we'll be working on tying up any iOS8 related loose ends on the 17th.
Thanks for using Crittercism!
