Answer 1

Swift 4

regardless of using didFinishPickingMediaWithInfo or didFinishRecordingToOutputFileAtURL you can:

// needed only for didFinishPickingMediaWithInfo
let outputFileURL = info[UIImagePickerControllerMediaURL] as! URL

// get the asset
let asset = AVURLAsset(url: outputFileURL)

// get the time in seconds
let durationInSeconds = asset.duration.seconds
