var encoder = ObjectEncoder() encoder.encodingStrategies[Date.self] = .iso8601 let encoded = try encoder.encode(Date(timeIntervalSince1970: 1000)) encoded == "1970-01-01T00:16:40Z" // true var decoder = ObjectDecoder() decoder.decodingStrategies[Date.self] = .iso8601 let decoded = try decoder.decode(Date.self, from: encoded) decoded == Date(timeIntervalSince1970: 1000) // true
