While trying to debug my view hierarchy, I get the following error:
Error: Unable to capture view hierarchy. Details: No plist data for fetching
Actually me also got the same type of error, but the truth is our app must in Running state. Because the "Debug View capture hierarchy" area appears only while the app is running.
See my screen shot
In Step 1: Select your app first
In Step 2: Now select Debug hierarchy button
If this doesn't work then go to Debug in menu on the top bar of Xcode
->Debug -> view debugging -> Capture View Hierarchy
I solved my problem like this.
