URLResourceValue and setResourceValues Swift 3

I'm trying to figure out how i should proceed fox fixing below code using Swift 3.

let paths = NSSearchPathForDirectoriesInDomains(.libraryDirectory, .userDomainMask, true) as NSArray

for path in paths {
let dir = path as! String
print("the paths are \(path)")
let urlToExclude = NSURL.fileURL(withPath: dir)
do {

try urlToExclude.setResourceValue(NSNumber(value: true), forKey: URLResourceKey.isExcludedFromBackupKey)

} catch { print("failed to set resource value") }

The error that i'm getting is this

I used the above code for excluding files from backing up to the iCloud and it used to work fine for previous version of Swift but after updating to Xcode 8 I'm just stuck.

I would really appreciate any help or suggestions.

The Xcode suggestion "Use struct URLResourceValues and URL.setResourceValues(_:) instead" is prompting you to write something like this:

let paths = NSSearchPathForDirectoriesInDomains(.libraryDirectory, .userDomainMask, true)

for dir in paths {
    print("the paths are \(dir)")
    var urlToExclude = URL(fileURLWithPath: dir)
    do {

        var resourceValues = URLResourceValues()
        resourceValues.isExcludedFromBackup = true
        try urlToExclude.setResourceValues(resourceValues)

    } catch { print("failed to set resource value") }

Please try.
