Swift 3 - JSON Parsing

I am new to Swift and learning the basics.

What I want to ask is, is it a good practice to parse JSON in terms of error handling as below?

if  let email = data["Email"] as? String,
                let name = data["Name"] as? String,
                let surname = data["Surname"] as? String,
                let identityNumber = data["IdentityNumber"] as? String ?? nil,
                let regAddress = data["RegistrationAddress"] as? String,
                let regZipCode = data["RegistrationZipCode"] as? String,
                let phoneNumber = data["PhoneNumber"] as? String,
                let city = data["City"] as? String {

                let user = User(name: name, surname: surname, idNumber: identityNumber, regAddress: regAddress, regZipCode: regZipCode, phoneNumber: phoneNumber, city: city)
            }

Any help or answer is appreciated.

Sometimes it will not have any problem, but if the values or result may get nil. so at that time the app will get crash.
