well, it turns out i am not the only one
https://github.com/xamarin/Xamarin.Forms/issues/11183
seems to be a bug in listview.
downgrade to Xamarin.Forms version 4.6.0.847 will solve this problem

I've been able te reproduce it while using the Xcode accessibility inspector.
The concerning page holds numerous UI elements which used to work fine with voice over.
I've been looking all over the internet but up to now it feels like we're the only one with this problem.

After upgrading MvvmCross from version 4 to 5.1.1, I get the a TargetInvocationException at my entrypoint (UIApplication.Main(...)). This is the class:
using UIKit;
namespace sample
{
public class Application
{
// This is the main entry point of the application.
static void Main(string[] args)
{
// if you want to use a different Application Delegate class from "AppDelegate"
// you can specify it here.
UIApplication.Main(args, null, "AppDelegate");
}
}
}
And this is the exception that is thrown:

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
The app has been terminated.
Failed to Stop app: An error occured on client IDB471022 while executing a reply for topic xvs/idb/4.7.10.22/stop-app
The app has been terminated.
The app works fine on mvvmcross 4, and the migration guide shows no surprises: https://www.mvvmcross.com/documentation/upgrading/upgrade-to-mvvmcross-50. I can't seem to debug anything. The only breakpoint that triggers is on UIApplication.Main, and step-into stops quite quickly and results in the given exception. Where do I start searching in order to fix this?
[edit]
This is still an issue, even with MVVMCross 5.7. It tries to instantiate a MainView class, which extends from MvxViewController. This happens before there is any code executed from my Setup class.
Looking at the line 26 that fails in MvxBindingViewControllerAdapter:
IosView.BindingContext = Mvx.Resolve<IMvxBindingContext>();
Where IosView is the ViewController cast to IMvxIosView. This suggests that your ViewController does not implement IMvxIosView. Since it seems like it is the only thing that would be null in this case.
I finally found the answer. I had 2 major versions of MvvmCross included in the project. I've now upgraded everything to 6.x.x. and the application starts up.
I'm trying to create a UIWebView and loading a page. When the loading finishes, I want to move to another screen.
The following code works on the iOS simulator, but not on a device.
I tried following this answer (Monotouch + UIWebView = Random Crashes), promoting the NSUrlRequest to become a global variable, but the error persists.
I tried using a try{} catch{} but it doesn't grab any exceptions when it crashes. it's driving me insane :)
void LoadSite(){
webView = new UIWebView (new CGRect (0, 0, 300,300));
string url = "http://google.com";
NSUrlRequest request = new NSUrlRequest(new NSUrl(url));
View.AddSubview (webView);
webView.LoadFinished+= (object sender, EventArgs e) => {
// CRASHES
};
webView.LoadRequest(request);
}
Any idea of how to solve this?
Thank you.

Testing on an iPhone 4S.
I'm stumped as to what I am doing wrong. I display the ABPeoplePickerNavigationController modally after subscribing to the SelectPerson event. Within the event, I take a copy of the data I need (only holding references to strings, not to any of the AdressBook or Person instances), and then close the modal dialog:
private string selectedPersonFirstName;
private string selectedPersonEmail;
private string selectedPersonPhone;
private void SelectContact()
{
var peoplePicker = new ABPeoplePickerNavigationController();
peoplePicker.Cancelled += (sender, e) =>
{
selectedPersonFirstName = null;
selectedPersonEmail = null;
selectedPersonPhone = null;
peoplePicker.DismissViewController(true, null);
};
peoplePicker.SelectPerson += (sender, e) =>
{
var selectedName = String.Format("{0} {1}", e.Person.FirstName, e.Person.LastName);
selectedPersonFirstName = e.Person.FirstName;
if ( e.Person.GetEmails().Count > 0)
selectedPersonEmail = e.Person.GetEmails().FirstOrDefault().Value;
if ( e.Person.GetPhones().Count > 0)
selectedPersonPhone = e.Person.GetPhones().FirstOrDefault().Value;
peoplePicker.DismissViewController(true, null);
};
PresentViewController(peoplePicker, true, null);
}
At some point later when the GC kicks in, it crashes:

=================================================================
Has anyone seen anything like this before? I'm up for workarounds at this point as I need it more reliable for a demo ASAP (not for app store submission yet).
It looks like a bug. Something gets released one time too many and crash.
You can, for your demonstration purpose, work around it by defining CFRetain like this:
[System.Runtime.InteropServices.DllImport ("/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation")]
static extern IntPtr CFRetain (IntPtr obj);
and use it on the _AddressBook, like that
peoplePicker.SelectPerson += (sender, e) => {
CFRetain (peoplePicker._AddressBook);
var selectedName = String.Format("{0} {1}", e.Person.FirstName, e.Person.LastName);
...
That will balance the count and avoid the crash.
Update: bug filled, you can c.c. yourself the the bug report to know when a fix will be released.
After I have updated monotouch to Version 5.2.13 my App crashes when I touched inside a UIButton.
About my Code: (it's a question of a LoginView):
I have a UIViewController which includes a ScrollView.
For each User the ScrollView provides a UIView (the UserImageView).
This UserImageView contains a UserImage, Username and so on. Over the UserImage lays a UIButton which should catches the Touch-Events to selected a User.
This Button causes the Exception below more precisely the HitTest method from the UIView.
I get the following Stacktrace:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
Here is the important Part of my Code:
public class LoginViewController : UIViewController
{
...
public override void ViewDidLoad()
{
...
BuildUserUI();
...
}
private void BuildUserUI()
{
currentIconLocation = new PointF(50, 10);
for (var i = 0; i < UserList.List.Count; i++)
CreateUserInGrid(UserList.GetUserByIndex(i));
}
private void CreateUserInGrid(LoginUser user)
{
var imgFrame = new RectangleF(currentIconLocation.X, currentIconLocation.Y, 140, 170);
var loginImg = new UILoginImage(imgFrame);
loginImg.Image = user.Image ?? defaultUserImage.CGImage;
loginImg.Name = user.Nachname;
if (!string.IsNullOrEmpty(user.Vorname))
loginImg.Name += ", " + user.Vorname;
loginImg.Tag = user.UserIndex;
loginImg.AddTarget(this, new Selector("ShowNumberPad:"), UIControlEvent.TouchUpInside);
loginImg.LoginUser = user;
scrollView.AddSubview(loginImg);
loginImages.Add(loginImg);
limitedScrollView.UserInteractionEnabled = false;
var newSize = new SizeF(scrollView.Frame.Size.Width, currentIconLocation.Y + imgFrame.Size.Height + 20);
scrollView.ContentSize = newSize;
limitedScrollView.ContentSize = new SizeF(limitedScrollView.Frame.Size.Width, limitedScrollView.Frame.Size.Height);
currentIconLocation.X += imgFrame.Size.Width;

I'm not sure your use of AddTarget is a good way to hook up a UIButton's click.
You should be using clickHelper.TouchUpInside to wire up click events. This is a standard C# event.
Another option would be to wire up an action to this event inside your XIB file in XCode.
