我有一个结构,我想保存到UserDefaults.这是我的结构

struct Song {
    var title: String
    var artist: String
}

var songs: [Song] = [
    Song(title: "Title 1", artist "Artist 1"),
    Song(title: "Title 2", artist "Artist 2"),
    Song(title: "Title 3", artist "Artist 3"),
]

在另一个ViewController中,我有一个附加到这个结构的UIButton

@IBAction func likeButtonPressed(_ sender: Any) {   
   songs.append(Song(title: songs[thisSong].title, artist: songs[thisSong].artist))
}

我想要它,以便每当用户也点击该按钮时,它会将结构保存到UserDefaults,这样每当用户退出应用程序然后打开它时,它就会被保存.我该怎么做？
