How to download video from url and save it in to document directory in iOS

Answer 1

You can also implement same in Swift 2.0

class func downloadVideo(videoImageUrl:String)
{
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
        //All stuff here

        let url=NSURL(string: videoImageUrl)
        let urlData=NSData(contentsOfURL: url!)

        if((urlData) != nil)
        {
            let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]

            let fileName = videoImageUrl.lastPathComponent //.stringByDeletingPathExtension

            let filePath="\(documentsPath)/\(fileName)"

            //saving is done on main thread

            dispatch_async(dispatch_get_main_queue(), { () -> Void in

                 urlData?.writeToFile(filePath, atomically: true)
            })

        }
    })

}
