I am trying to test out the new Google SDK for iOS using the GoogleMapsSample on GitHub, however, every time I run the app crashes trying to create an instance of GMSMapView. This is happening when trying to run on both the simulator and the device.
I have enabled the SDK from the developer console and updated the GMSServices.ProvideAPIKey call to use my iOS API key, from what I have read that is pretty much all that's required?
I did notice this bug which was logged against the actual SDK which mentions an issue relating to OpenGL so not sure if that's what the issue is here. However, as I can't get access to a log using the simulator I ran it on the device and checked the log out using XCode and the error does seem to relate to this - stack trace:

Update #2
Google suggested a workaround and it has been implemented. I have successfully deployed to device :) you can find the working solution on MonoTouch-Bindings Repo
Google will fix this on their upcoming release as stated here.
Happy Coding
Update
There is a bug on Google Maps that makes it impossible to use it in Xamarin.iOS, this bug has been reported to google here
http://code.google.com/p/gmaps-api-issues/issues/detail?id=5018
Please Star it so google notices and fixes it faster ;)
I have updated the bindings to version 1.1.0 of Google Maps you can find them here https://github.com/mono/monotouch-bindings/tree/master/GoogleMaps
Please note I have not updated the sample to reflect the Api changes yet.
Hope this helps
Alex
Xamarin did not update to the newer version since they did the last update on 14 december. I believe that this crash relates to this issue. Maybe the API keys you can generate today are just build for 1.1.0 and newer.

I received a crash in iOS12.
The way to reproduce:
1.Play a video with UIWebView, then the video will play in fullScreen.
2.After the video start play, tap the left-top reduced Button to stop the video.
3.Replay it and the video will still in fullScreeen.
4.Repeat step2 and step3 several times.
5.Normal speed, at most 10 times, the crash will come.
Some detail info of the crash:

Anyone have any idea?
ps.There are a similar question at Multiple UIWebView WebCore Crashes
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
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.
I am using a binding project to wrap ECSlidingViewController for use with MonoTouch/Xamarin. I have this setup. However when I attempt to open the menu (by triggering a segue on button click) the app crashes with no error report, nor anything in the application output. All I have to go on is the following crash report I retrieved from the console. Can anyone shed any light on the problem?
The only code being executed is:
// in ViewDidLoad()
menuButton.TouchUpInside += (object sender, EventArgs e) => ToggleMenu();
private void ToggleMenu()
{
PerformSegue("ReturnToMenu", this);
}
The mammoth crash report. I've removed the irrelevant sections and the 20-odd other threads it ilsted.

This is mostly a guess, but it looks like it's hitting a bug inside Xamarin.iOS where we don't generate the proper binding code for Objective-C blocks when those blocks can be null (this has already been filed as a bug here).
If you had a complete test project I can run I'd be able to confirm this quickly.
If this is not the right forum to ask such question, please point me to the right one.
The app I am working on uses the location of the user and alert the user when certain condition is met. The alert is in form of vibration and a playback of a small file. During testing on the device, the phone vibrates and the audio clip plays for 2 seconds (the clip is about 9 secs long) and the app crashes. The crashes are consistent on the device. On the simulator, occasionally, I see the crashes but not consistent.
The trigger to set off the alert is in the delegate method of CLLocation class
- (void)locationManager:manager didUpdateToLocation:fromLocation:
Here's the code fragment (ivLocMgr is an instance variable)
if ((!ivAlertAlreadyShown) && (<test for trigger condition)) {
ivAlertAlreadyShown = YES;
[self obviousNotification];
[ivLocMgr stopUpdatingLocation];
[ivLocMgr release], ivLocMgr = nil;
}
Can the [ivLocMgr stopUpdatingLocation]; be the root cause?
Any and all help is greatly appreciated.

Found the answer on Apple Developers' Forum:
