App crashes when i use nsmutablestring iOS swift

-

  Solution:

@property (nonatomic, assign) NSMutableString* str;


When i use the above line try to run the app it crashes.


Because it's a mutable value.. NSMutableString and NSString are came from nsobject with mutble value..


@property (nonatomic, weak) NSMutableString* str;


You must have to use like above the app will works fine..You cannot be able to assign a value to the mutated objects.You must use that as weak property..


Happy coding...
