Description E Minbiole 2013-12-03 11:33:56 UTC
According to the documentation if NULL is specified for the predicate parameter, the method should display all discovered accessories. Instead, it throws a System.ArgumentNullException.

This is the call:

EAAccessoryManager.SharedAccessoryManager.ShowBluetoothAccessoryPicker(null, delegate { Console.WriteLine("Completed"); });

Both parameters accept null.

I have verified this issue. Following are the verified steps:

1. Created a sample iOS project.
2. Added below code:

delegate { Console.WriteLine("Completed"); });

3. Debug successfully application and not getting "System.ArgumentNullException" exception.

Checked With:
All Mac 
XS 4.2.3 (build 23)
