Sample settings plist with four boolean-valued prefs

As discussed on the Xamarin forums.  If you have a Settings.bundle/Root.plist which has Integer or Boolean preferences, the build fails with the following exception:

ERROR [2013-08-11 00:50:36Z]: System.InvalidCastException: Cannot cast from source type to destination type.

Comment 1 Jeffrey Stedfast 2013-08-12 12:56:08 UTC
Looking over the documentation for PreferenceSpecifiers (Root.plist schema), all of the defined Dictionary children of the PreferenceSpecifiers array have a 'Type' key of type string, none of them allow boolean or integer values for the 'Type' key.

If you want a toggle button, the 'Type' key should contain "PSToggleSwitchSpecifier"

I mean, I can fix the code to be more fault tolerant when reading that file but are you sure it's valid?
Comment 2 Eric Smith 2013-08-12 13:44:52 UTC
Okay, thanks.  Turns out that I was confused by UI of the plist editor.  Entirely my mistake.  Sorry about that.
Comment 3 Jeffrey Stedfast 2013-08-12 14:24:22 UTC
Well, this is still a valid bug :-)

Turns out that fixing this is really just a 1-line patch to our plist Dictionary implementation.

That said, this is now fixed in git master to not throw this exception anymore and handles the error condition much more gracefully.
