After an Album, Playlist, or collection of songs have been added to the ApplicationMusicPlayer queue, clearing the queue can be easily accomplished with:
ApplicationMusicPlayer.shared.queue.entries = []
This transitions the player to a paused state with an empty queue.
After queueing a Station, the same code cannot be used to clear the queue. Instead, it causes the queue to be refilled with a current and next MusicItem from the Station.
What's the correct way to detect that the ApplicationMusicPlayer is in the state where it's being refilled by a Station and clear it? I've tried the following approaches with no luck:
# Reinitialize queue
ApplicationMusicPlayer.shared.queue = ApplicationMusicPlayer.Queue()
# Create empty Queue
let songs: [Song] = []
let emptyQueue = ApplicationMusicPlayer.Queue(for: songs)
ApplicationMusicPlayer.shared.queue = emptyQueue

I'm attempting to write a function similar to the example shared over in https://developer.apple.com/forums/thread/700683 for playing a MusicItem using the SystemMusicPlayer. Currently, this function starts like this:
func play<MusicItemType>(item: MusicItemType) async throws
where
MusicItemType: FilterableMusicItem,
MusicItemType: Decodable,
MusicItemType: PlayableMusicItem
{
var queue : MusicKit.MusicPlayer.Queue?
switch MusicItemType.self {
case is Playlist.Type:
let request = MusicCatalogResourceRequest<Playlist>(matching: \.id, equalTo: MusicItemID("\(item.id)"))
let response = try await request.response()
if let responseItem = response.items.first {
queue = MusicKit.MusicPlayer.Queue(for: [responseItem])
}
case is Album.Type:
let request = MusicCatalogResourceRequest<Album>(matching: \.id, equalTo: MusicItemID("\(item.id)"))
let response = try await request.response()
if let responseItem = response.items.first {
queue = MusicKit.MusicPlayer.Queue(for: [responseItem])
}
...
I'd love to clean up this case statement and instead construct a MusicCatalogResourceRequest using the generic MusicItemType type parameter, but I haven't yet been able to figure how to construct a KeyPath that matches the KeyPath<MusicItemType.FilterType, Value> type expected. Does anyone have any examples of interacting with MusicCatalogResourceRequest in a generic fashion that they'd be willing to share? Thanks!
