我尝试编译我的第一个 iOS Hello 应用。
我有
ViewController.swift
//
// ViewController.swift
// My First Project
import UIKit
class ViewController: UIViewController {
// Declare components
@IBOutlet weak var inputLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
@IBAction func submitBtn(_ sender: Any) {
inputLabel.text = "Hello World"
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
我保留
获取构建成功
但大约 5 秒后，我得到了这个
