HiI'm building a today extension which works fine on iOS13+ but somehow it doesn't work for the versions below.On other versions I get following error:2019-12-20 08:45:41.741 MyWidget[4730:53043] Unknown class _TtC14MyWidget19TodayViewController in Interface Builder file.2019-12-20 08:45:41.850 MyWidget[4730:53043] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIViewController 0x7ffe59401f10> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key loginViewNew.'At first I thought it was caused because in the properties under Interface Builder Document builds for was set to iOS13 and later, so I changed this in my storyboard and all my other .xib files but this did not solve the problem, I still get the same error.I also checked my outlets and there are no errors there as well, storyboard can find my TodayViewController class so I have no clue what the problem can be.Does anyone have suggestions for solving this problem?
