I have a method which is returning NSMutableData. I need to pass this NSMutableData to another method but that method is expecting only NSData. I am trying to find any method/solution to convert NSMutableData to NSdata. But still no luck.
In Objective C, it can be done like this
NSData *immutableData = [NSData dataWithData:mutableData];
I am not sure how it can be done in Swift?Can someone help me in this?
Simply pass the
NSMutableData to any method that expects
NSData. Since it's a subclass, it will work fine.
But if you really want to do the conversion, simply do (Swift 3):
let data = someNSMutableDataVariable.copy() as! NSData
let data = NSData(data: someNSMutableDataVariable as Data)
It may make sense to update your code to use
Data instead of
NSData. Just like using
String instead of
