如何在字典循环中获取键、值和索引？

Question

I have a dictionary and I want to loop it and get the key, value and it's index as Int , but with my loop, I'm just only getting the key and value, how can I get the index?

This is my code for getting its key and value:

var myDict:[String: String]?

func getKeyValueIndex() {
    if let myDict = myDict {
        for (key, value) in myDict { print(key, value) }
    }
}

My expected result was to print the index too print(key, value, index)

Dictionaries are unordered, so all you can do is to enumerate through the dictionary, like this:

func getKeyValueIndex() {
    if let myDict = myDict {
        for (index, dict) in myDict.enumerated() { print(index, dict.key, dict.value) }
    }
}
