macOS NSArray storing MutableArrays

[larswik]

Quick question, I don't think I need to post code. I understand NSArrays can not be changed. But if I create an NSArray that contains NSMutableArrays, am I able to change the data in the MutableArrays, or is everything immutable since it is stored in an NSArray?

Yes, you can change the mutable arrays in the wrapper array. NSArray doesn't know what they are other than some NSObject.

Thanks, tracking down some code problems and wanted to eliminate that as a possible problem.
