How to read file data Applications document directory in swift?

Question

I am new at Swift programming language. I want to download a movie from some tube servers and want to play offline. I am using Alamofire for downloading part. I can list the file(s) with that:

var file:String?
if let files = NSFileManager.defaultManager().contentsOfDirectoryAtPath(documentsDirectory, error: &error) as? [String] {
                for filename in files {
                    // do stuff with filename
                    file = filename
                    println(filename)
                }
            }

But the problem is how i can use that file for my purpose. Let assume its image file and i want to show in imageview.

myImageView.image = UIImage(contentsOfFile: file) /* doesn't work*/

thank you for any help.

Answer 1

For Swift 2 you have to change something. Note: stringByAppendingPathComponent is not more available on String (only NSString):

var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString
var getImagePath = paths.stringByAppendingPathComponent("filename")
myImageView.image = UIImage(contentsOfFile: getImagePath)

Answer 2

Try this code:

var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var getImagePath = paths.stringByAppendingPathComponent("filename")
myImageView.image = UIImage(contentsOfFile: getImagePath)

I hope this work.
