问题 Since Xcode 10.1(maybe 10) when I create a Unit test file I don't have calls super.tearDown() and super.setUp() . I've not seen such changes in release notes. In documentation https://developer.apple.com/documentation/xctest/xctestcase/understanding_setup_and_teardown_for_test_methods are still here.

问题 One of my projects is a System Preference Pane. With 10.11, Xcode's debugger can't debug it as I get a "can't attach to System Preferences because of System Integrity Protection".

问题 I use UIPopoverController to popover a window. I use preferredContentSize to set the size. Then, I use Push a new view controller with larger size. When the child view pop up, I like to recover the window to original size. But seems not work. I already put the self.preferredContentSize = myWindowSize; But it seems can not recover. In iOS6 or before, I set the contentSizeForViewInPopover to CGSizeZero, then set the proper size. But on iOS7, it will make the popup disappear. 回答1: This solved it
