Description Larry Pauley 2016-09-14 17:27:23 UTC
I have iOS Simulator 9.3 and 10.0 in XCode on my Mac. ELCImagePicker work fine with 9.3, but just stops working when I click the picker button (+).  I have tried to include the ELCImagePicker solution with my ELCImagePickerSample solution to see what line the DLL seems to be having a problem, but the ELCImagePicker solution is not providing any debug information.  It just dies once I click the picker for an image library.

I have tested my current code with an iPhone 6 Plus with iOS 10.0 and it works, but the simulator under XCode 10 does not work.

I have included some output from Visual Studio 2015, after I click the PICKER button.  I hope this helps some.

Here is output from Visual Studio 2015 when I click the PICKER BUTTON:

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.
Launch succeeded. The app  'ELCImagePickerSample' has been successfully launched on 'iPhone 6 iOS 10.0'.
The app has been terminated.
Comment 2 Larry Pauley 2016-09-14 19:21:25 UTC
It would appear it has something to do with a "PRIVACY VIOLATION".
Comment 3 Larry Pauley 2016-09-14 19:44:05 UTC
I found the solution to this problem here:


If anyone else has this problem, just add the following to your XML file "Info.plist" in Visual Studio.  iOS 10 now absolutely requires you supply descriptions such as:

  <string>For selecting pictures</string>
Comment 4 David Humphreys 2016-11-01 21:55:30 UTC
I have updated the samples and the documentation to reflect the new requirements
