Deleting contents of text file

I'm reading and writing to a text file. There is an instance where I want to delete the contents of the file (but not the file) as a kind of reset. How can I do this?

if ((dirs) != nil) {
    var dir = dirs![0]; //documents directory

    let path = dir.stringByAppendingPathComponent("UserInfo.txt");
    println(path)
    let text = "Rondom Text"

    //writing
    text.writeToFile(path, atomically: false, encoding: NSUTF8StringEncoding, error: nil)

    //reading
    let text2 = String(contentsOfFile: path, encoding: NSUTF8StringEncoding, error: nil)

    println(text2)
Solution

  • Simply write an empty string to the file like this:

    let text = ""
text.writeToFile(path, atomically: false, encoding: NSUTF8StringEncoding, error: nil)
