/* 
Example of a way to read in serialized data (eg. json) when Swift adds built in
Codable / Hashable / Equatible to a struct / class that previously didn't, yet they decided
to serialize things differently than you did in existing code.

In this example, I had previously serialized int2 to a dictionary with x and y keys for its
x and y properties. Swift 5 serializes this as an array, which is incompatible and causes
the whole json file to fail to deserialize.

You could write a custom init(from decoder: Decoder for each class using the problematic struct,

let player = AVPlayer()

func playFileAtURL(url: NSURL) {  
    let asset = AVAsset.assetWithURL(url) as AVAsset

    let duration = asset.duration
    let durationInSeconds = CMTimeGetSeconds(duration)

    let item = AVPlayerItem(asset: asset)
    let params = AVMutableAudioMixInputParameters(track: asset.tracks.first! as AVAssetTrack)
