How can I read a file in a swift playground

Question

Im trying to read a text file using a Swift playground with the following

let dirs : String[]? =    NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory

String.stringWithContentsOfFile is DEPRECATED and doesn't work anymore with Xcode 6.1.1

Create your documentDirectoryUrl

let documentDirectoryUrl = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first! as NSURL

To make sure the file is located there you can use the finder command Go To Folder e copy paste the printed documentDirectoryUrl.path there

println(documentDirectoryUrl.path!)
// should look like this: /Users/userName/Library/Containers/com.apple.dt.playground.stub.OSX.PLAYGROUNDFILENAME-5AF5B25D-D0D1-4B51-A297-00015EE97F13/Data/Documents

Just append the file name to the folder url as a path component

let fileNameUrl = documentDirectoryUrl.URLByAppendingPathComponent("ReadMe.txt")
var fileOpenError:NSError?

Check if the file exists before attempting to open it

if NSFileManager.defaultManager().fileExistsAtPath(fileNameUrl.path!) {

    if let fileContent = String(contentsOfURL: fileNameUrl, encoding: NSUTF8StringEncoding, error: &fileOpenError) {
        println(fileContent)        // prints ReadMe.txt contents if successful
    } else {
        if let fileOpenError = fileOpenError {
            println(fileOpenError)  // Error Domain=NSCocoaErrorDomain Code=XXX "The file “ReadMe.txt” couldn’t be opened because...."
        }
    }
} else {
    println("file not found")
}
