externalIds Type

[kimfucious]

When I receive a response from a track search, using this wonderful library, I get a response that includes the optional property of externalIds, which I'd like to use in the app I'm working on.

What I'm seeing is something like this: externalIds: Optional(["isrc": "GBCBR2100039"])

When I've accessed this property before, via the standard Spotify Web API (not yours), the property is an ExternalIdObject, as referenced here, with possible keys of: ean, isrc, & upc.

I'm wondering if the response provided by this library is intentionally returning an array, rather than an object.

The term externalIds is somewhat misleading, as it seems to suggest a list of things, rather than a mapping of things, so maybe this is the reason.

Regardless, I can work with the response as is, but I thought I'd bring the above to your attention and see if you have any feedback.

Thanks.

Actually, that's a Dictionary, not an array... 😕

The type of Track.externalIds is [String : String]?, not an array. This matches the structure of the JSON payload.

This is the term chosen by Spotify, not me. To me the term, does not specifically imply an array or a mapping. You can easily inspect the declared type of a property in Swift, so I don't understand what the issue is.

Thanks for the clarification, @Peter-Schorn

Frankly, I'm used to working in JS, so the Dictionary threw me. My bad.

I can use the following to get at the data:

track.externalIds?["isrc"]
