How to copy elements of a NSDictionary to a swift Dictionary?

Question

I need to mutate a NSDictionary in swift.

Hence I need to copy the elements of that NSDictionary to a swift Dictionary.

Something like the Objective-C equivalent of

[[NSMutableDictionary alloc] initWithDictionary:(nonnull NSDictionary *)];

Answer 1

A Dictionary is a struct in swift, which is a value type.

let firstDictionary = ....
let copyOfirstDictionary = firstDictionary// This will copy the contents from first dictionary to another.
