Answer 1

It seems like that you are setting the corner radius(working with layers) of a view.

Solution 1:

Set environmental variable via menu: Product-> Scheme->Edit Scheme. In "Run" item, locate "Arguments" tab, you'll see "Environmental Variables" in the tab, Add CG_CONTEXT_SHOW_BACKTRACE and set its value to YES.

Solution 2:- If above solutions does not work for you, then remove the UIViewControllerBasedStatusBarAppearance from Info.plist.
