JSON output from API Call

OutputJson.swift

/*
JSON from API calls are provided as Data objects, not strings.
While debugging, it is often necessary to output the JSON
string somewhere. This snippet does that.
*/
if let data = data {
    print("JSON = " + String(data: data, encoding: .utf8)! )
}

// Notice the use of ! since the String constructor might fail.
// Here is an alternative if you want to avoid forced unwrap

if let data = data {
    print("JSON = " + String(data: data, encoding: .utf8) ?? "Error converting to string" )
}
