Xcode crashes when "Automatically manage signing" ticked


I am trying to test my ionic app in iphone. I am following the intructions of the below link


When I open the xcode project in platform/ios, In the xcode I selected the “Automatically manage signing” and then the team as instructed in the above link for the users who use xcode 8 or higher.

When I do this my xcode crashes even before I click the play button in the xcode.

My iphone is a iphone 4s which runs iOS version 9.3. Any suggestions or help? Thanks

Same here…
Always when try Automatically manage signing
