ios - The document picker ... failed to launch -


i have created own documentpickerextensionviewcontroller , want able open in excel app on ios. in office app press open -> ... more -> locations , choose extensions name. after 2 seconds of loading dialog pops saying "the document picker ... failed launch (0)".

i can't find error when googling. know might have done wrong?

i found solution. tried creating new test app , document provider xcode worked out of box. realised xcode creating document provider project file provider project , missing in xamarin project file provider since won't using icloud. after adding file provider project no longer got error message.
