TableView Constraints 이용해 가득 채우기 

 

프로토콜 채택 Fix

 

 

Table View Cell Constaints(margin 5)

 

네트워킹

1. URL 만들기
   • URL(string: String)
2. URLSession 만들기
   • URLSession(configuration: URLSessionConfiguration)
3. URLSesstion 인스턴스에게 task 주기
   • URLSession인스턴스.dataTask(with:completionHandler:)
4. tsak 시작하기
   • URLSessionTask인스턴스.resume()

함수 안 옵셔널 풀기

if - let

 func getData() {
    if let url = URL(string: movieURL) {
        print(url)
    }
}

 

guard - let 

func getData() {
    guard let url = URL(string: movieURL)  else {
        return
    }
    print(url)
}

언래핑 된 url 변수를 guard 문 밖에 있는 코드가 사용 가능함

URLSession | Apple Developer Documentation

 

func getData() {
        guard let url = URL(string: movieURL)  else {
            return
        }
        let session = URLSession(configuration: .default)
        session.dataTask(with: url, completionHandler: <#T##(Data?, URLResponse?, (any Error)?) -> Void#>)
    }

<#T##(Data?, URLResponse?, (any Error)?) -> Void#> 이부분 Enter 누르면

func getData() {
        guard let url = URL(string: movieURL)  else {
            return
        }
        let session = URLSession(configuration: .default)
        session.dataTask(with: url) { <#Data?#>, <#URLResponse?#>, <#(any Error)?#> in
            <#code#>
        }
    }

자동으로 후행 클로저로 만들어줌
