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

I added Dictionary extension

extension Dictionary {   
  func cloneWith(_ dict: [Key: Value]) -> [Key: Value] {
    var result = self
    dict.forEach { key, value in result[key] = value }
    return result  
  }
}

you can use cloneWith like this

 newDictionary = dict.reduce([3 : "efg"]) { r, e in r.cloneWith(e) }
