How to get the last dictionary element on Swift?

How to get last element on Swift ?

var test: [Int:String] = [Int:String]()
test[1] = "CCC"
test[3] = "AAA"
test[2] = "BBB"

I am trying to get Int 3. I try to use endIndex like this 

let (key,value) = test.endIndex

and 

print(test.endIndex)

but it does not work.

You haven't been very clear, but I think you're trying to get the last element of an ordered dictionary. Swift's native Dictionary type is unordered, so you will have to manually sort it:

test.keys.sort().last.map({ ($0, test[$0]!) })

In your specific case, the code above will return Optional((3, "AAA")) (i.e. typed Optional<(Key, Value )>).
