[Swift] Firebase RealtimeDatabase Write Data

데이터를 Firebase에 dictionary형태로 writing해보겠습니다.

 

서점에서 고객관리 데이터를 넣고싶다고 가정 해보면

 

 

override func viewDidLoad() {

        super.viewDidLoad()

        saveCustomers()

    }

//saveCustomer()호출

 

 

---

 

func saveCustomers() {

            let books = [Book(title: "BbiDdiBaBiDiBu", author: "Chul"), Book(title: "Machine", author: "Young")]

            let customer1 = Customer(id: "\(Customer.id)", name: "ChaSsi", books: books)

            Customer.id += 1

            let customer2 = Customer(id: "\(Customer.id)", name: "Ming", books: books)

            Customer.id += 1

            let customer3 = Customer(id: "\(Customer.id)", name: "DDong", books: books)

            Customer.id += 1

            

//db에 write

            db.child("customers").child(customer1.id).setValue(customer1.toDictionary)

            db.child("customers").child(customer2.id).setValue(customer2.toDictionary)

            db.child("customers").child(customer3.id).setValue(customer3.toDictionary)  

        }

struct Customer {

    let id: String // static var id와 차이

    let name: String

    let books: [Book]

    

    var toDictionary: [String: Any] {

        let booksArrary = books.map { $0.toDictionary }

        let dict: [String: Any] = ["id": id, "name": name, "books": booksArrary]

        return dict

    }

    static var id: Int = 0

}

//고객 structure

---

struct Book {

    let title: String

    let author: String

    

    var toDictionary: [String: Any] {

        let dict: [String: Any] = ["title":  title, "author": author]

        return dict

    }

}

//책 structure

결과

 

 

서버에 잘 들어간 것을 확인 할 수 있었습니다.~
