How to append elements into a dictionary in Swift?

Question

I have a simple Dictionary which is defined like:

var dict : NSDictionary = [ 1 : \"abc\", 2 : \"cde\"]

Now I want to add an element into t

Answer 1

if you want to modify or update NSDictionary then first of all typecast it as NSMutableDictionary

let newdictionary = NSDictionary as NSMutableDictionary

then simply use

 newdictionary.setValue(value: AnyObject?, forKey: String)
