Error Force Unwrapping Artist! (var artist = Artist!)

var artist = Artist!

is throwing the following error:

(Expected member name or constructor call after type nameAdd arguments after the type to construct a value of the type)

(Use '.self' to reference the type object)

(Using '!' is not allowed here; perhaps '?' was intended? Replace '!' with '?')

I managed to find a work around to this problem by explicitly declaring some fake data at initialization.

  • THIS IS NOT A GOOD SOLUTION for many reasons but DOES allow you to continue with the lesson
//class AlbumListController: UITableViewController
var artist : Artist = Artist(id: 1, name: "", primaryGenre: .pop, albums: [Album]())

NOTE: Later on in the video series, Pasan DOES go back and correct this. Turns out he did this intentinally to prove a point to NEVER force unwrap values.

If you want to see Pasan goes over the the solution in a much later lesson go ---> HERE (time stamp 11:05)

However, I advise you use my work around in your AlbumListController & similar in AlbumDetailController to further learn the content being taught

//class AlbumDetailController: UITableViewController
var album: Album = Album(id: 0, artistName: "", name: "", censoredName: "", artworkUrl: "", isExplicit: false, numberOfTracks: 0, releaseDate: Date(), primaryGenre: .pop)
