[swift-users] Why can I not filter or map a dictionary to another dictionary?

[Vincent O'Sullivan]

Ah.  Having seen the other answers, I can now see the implied question.

    You can.  You just need to get the syntax right:
    
    let smallerDictionary = bigDictionary.filter { (key, value) in <some test returning Bool> }
    
    let bd = [1:"A", 2:"B", 3:"C"]
    let sd = bd.filter{(k, v) in
        k > 1}
    dump(sd)

        It seems fairly natural to want to do this:
        
        let bigDictionary = ...
        let smallerDictionary = bigDictionary.filter { key, value in <some test returning Bool> }
        
        Similarly, it seems natural to want to map this way.
        
        Am I overlooking something?
