let data = “””{“idforuser”: 1,“globalid”: 2,“usertitle”: “test”,“complete”: true}“””

The implementation: nested JSON

Parsing data using coding

let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .iso8601
let readableDateFormatter = DateFormatter()
readableDateFormatter.dateFormat = "M-dd-yyyy HH:mm"
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .formatted(formatter)
