done with 3 hours
New findings: followings are new findings
- because struct Response is not used in ContentView, so need to adjust decode code
- maybe misssed to add specialRequestEnabled flag in sample code, but it might be assumed with other info.
following a code for getting song data of Taylor Swift (with using Xcode 11.4)

1 2 3 4 |
// self.results = decodedResponse for eachResponse in decodedResponse.results { self.results.append(eachResponse) } |
here is the code after challenges
