According to the header doc of URL and URLResourceValues, you may need to write something like this:

(This code is assuming chosenURL is of type URL?.)

do {
    if
        let resValues = try chosenURL?.resourceValues(forKeys: [.creationDateKey]),
        let createDate = resValues.creationDate
    {
        //Use createDate here...
    }
} catch {
    //...
}

(If your chosenURL is of type NSURL?, try this code.)

do {
    if
        let resValues = try (chosenURL as URL?)?.resourceValues(forKeys: [.creationDateKey]),
        let createDate = resValues.creationDate
    {
        //Use createDate here...
        print(createDate)
    }
} catch {
    //...
}

I recommend you to use URL rather than NSURL, as far as you can.
