Swift 3: Set Finder label color

Question

I\'m trying to set the colored labels shown by the finder. The only function I know is setResourceValue. But this needs localized names!

Answer 1

I got it working without having to know the color name, thanks to the new URLResourceValues() struct and the tag numbers.

Knowing that each of these tag numbers represents a tag color:

0 None
1 Grey
2 Green
3 Purple
4 Blue
5 Yellow
6 Red
7 Orange

Make a URL of your file:

var url = URL(fileURLWithPath: pathToYourFile)

It has to be a var because we are going to mutate it.

Create a new URLResourceValues instance (also needs to be a variable):

var rv = URLResourceValues()

Set the label number like this:

rv.labelNumber = 2 // green

Finally, write the tag to the file:

do {
    try url.setResourceValues(rv)
} catch {
    print(error.localizedDescription)
}

In our example we've set the number tag to 2 so now this file is labeled with green color.
