Answer 1

Yes. when click the debug view hierarchy button ,the page has nothing, and print "[UIWindow viewForFirstBaselineLayout]: unrecognized selector sent to instance 0x7fb9dae257d0" .

To solved it, just be sure you are using the iOS systom not below iOS 9.0 and you will still use that function freely.
