导读：let file = "file.txt" if let dirs : [ String ] = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory,NSSearchPathDomainMask.AllDomainsMask, true ) as? [ String ] { let dir = dirs[ 0 ] //documents directory let path

let file = "file.txt" 
if let dirs : [String] = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory,NSSearchPathDomainMask.AllDomainsMask,true) as? [String] { 
    let dir = dirs[0] //documents directory 
    let path = dir.stringByAppendingPathComponent(file); 
    let text = "some text" //writing
    text.writeToFile(path,atomically: false,encoding: NSUTF8StringEncoding,error: nil); //reading 
    let text2 = String(contentsOfFile: path,error: nil) 
}
