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)".
