We had a project using wsdl2objc to generate webclient for iphone application. The app was working fine with SDK 3.2, till lately we tried to test it with the new Xcode (SDK 4.2) and it throws strange EXC_BAD_ACCESS directly after sending an asynchronous request and surely never getting a response. Here is the stack trace:

I know it has to be something about releasing NSOperation. But I could not go any further. Does anybody know if the NSOperation is changed since SDK 4.0? Did anybody successfully test wsdl2objc with SDK 4.0?
EDIT: The WSDL that I use is here.

We have a crash in MetalContext with over 3000 crashes in a single day on iOS 10 devices only. We are unable to track down the root of the error and google reveals nobody else have the same issue. Is there anyone who has any clues to where we can begin to look?

My app kept crashing with the same log, what fixed for me was a quick reset of device, i traced it to webView usage. I cant reset device every time so further testing revealed that i was using xcode 7.3 to build for ios10 that was the problem, after updating to xcode 8 and rebuilding the app i no longer get this crash. Hope this helps
I am getting the following crash only in iOS10.0.1. Its not giving me enough stack trace information. The only clue I have is , seems to be happening from WebView.Because it says "WebKitLegacy - [_WebSafeForwarder forwardInvocation:] ".
The crash log is given below. I have another crash group related to "updateSubviewsOfScrollContentViews" seems like all are related.
Any suggestions on this very helpful. Like how to debug this issue ? Where might be the problem?

What does this stack trace indicate? Crash caused by Xamarin.Media.MediaPicker.TakePhotoAsync on iOS8 on iPad2
I've logged a bug at...
https://bugzilla.xamarin.com/show_bug.cgi?id=22853
But I'd like to make sure that it is not something I'm doing. It works fine on iOS7.

It seems that what I was doing wrong was calling TakePhotoAsync from the Clicked event of an ActionSheet. The action sheet was still presented when the photo picker was presented. Pre iOS8 there must have been defensive code to silently work in this apparently illegal situation. The solution was to run the TakePhotoAsync in a BeginInvokeOnMainThread call. This queues the call on the main thread and allows the ActionSheet some space to finish closing.
My app have an UIWebView and I open a twitter oauth page with it.
when I open oauth page , it works well.
after I sign-in, it redirects to another page which have PIN code.
and It crashes down with logs below.
Is it a bug in 4.0 SDK?

I've got it.
This might have been a problem with auto generating link.
Turn off all detection of your UIWebView.
In my case, detection of phone numbers was issues.
Deactivating detection of links did it for me in the UIWebView!
I tried phone numbers first and that wasn't enough. Very strange.
I had exactly the same problem and, in my case, deactivating the phone number ditation did work.
webView.dataDetectorTypes = UIDataDetectorTypeLink;
Very strange issue.
