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?

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
We have a subclass of NSTableRowView that overwrites drawSelectionInRect: (which is internally called by drawRect:). This method needs to access the NSManagedObjectContext, so as a sanity check we have an assertion there that we are in the main thread. Now it turns out that sometimes Apple calls drawRect from a non-main-thread (example stack trace below). Does this mean it could even do that concurrently from two different threads? I.e. we have to take care of thread safety ourselves when overwriting drawRect: and using the data model?

NSView subclasses can draw concurrently in recent releases of OS X. This behavior can be turned off by overriding canDrawConcurrently and returning NO.
You might find it preferable to separate the view from the model a little more and isolate the data to be rendered from the CoreData managed data a bit; pull the data to be rendered out into a local-only representation and let AppKit concurrently update the view.

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.
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.

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.
