iOS Code Snippet File.Exists on Special folder

The need arose within a library to know if there was a Font in the Assets folder.
I didn't know if the developer had uploaded the font to the App, but if he didn't, the library would crash.

How to do? This was the solution

Dim no As NativeObject
Dim SpecialFolder As String = no.Initialize("NSBundle").RunMethod("mainBundle", Null).RunMethod("bundlePath", Null).AsString

If File.Exists(SpecialFolder,FontFileName) Then
    '...'
End If
