Я также получаю эту ошибку. , тогда я узнаю неправильный формат кода. в теге `` `.

перед:

 
``` objc 
view.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; 
``` 

после:

 
``` objc 
view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; 
``` 

то информация об ошибке исчезнет, ​​я не знаю, почему
