Answer 1

You can't sort dictionary in such easy way. I think dictionary is using some sort of tree data structure. But after sorting you get an array of tuples. So you can get keys in such way:

    let codeValueDict = ["us": "$", "it": "€", "fr": "€"]
    let sortedKeysAndValues = sorted(codeValueDict) { $0.0 < $1.0 }
    let keys = sortedKeysAndValues.map {$0.0 }
    let values = sortedKeysAndValues.map {$0.1 }
