Creating Apple Music developer token

Question

I'm trying to create a JWT with JWT.io for Apple Music api (ObjC) and for some reason it's not generating a token when I follow the format Apple says to do in documentation using (ES256). Does anyone know how to set up Apple Music api tokens for xcode?

You first have to create a MusicKit identifier and a private key using this guide from Apple. Then a token can be easily created using Swift-JWT from IBM in pure Swift.

It's more or less just an invocation of the SwiftJWT API:

let teamId = "yourTeamID"
let keyId = "yourKeyID"
let keyFileUrl = URL(fileURLWithPath:"/pathToYour/key.p8")

struct MyClaims: Claims {
    let iss: String
    let iat: Date?
    let exp: Date?
}

let myHeader = Header(kid: keyId)
let myClaims = MyClaims(iss: teamId, iat: Date(), exp: Date() +  24 * 60 * 60)
var myJWT = SwiftJWT.JWT(header: myHeader, claims: myClaims)

let token = try! myJWT.sign(using: .es256(privateKey: try! String(contentsOf: keyFileUrl).data(using: .utf8)!))

I created a simple example and a command line tool using the Swift Package Manager: SwiftJWTSample
