シミュレーションした直後に アプリケーションが停止されます。広告の貼り方に問題があるようなのですが、どこに問題があるのかわかりません。  
**キャッチされていない例外 'NSInvalidArgumentException'** とは何のことですか？。どうすればエラーが解消されるでしょうか。

**エラーコード↓**

question
swift xcode
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSLayoutConstraint for <GADBannerView:
[Generic Class
NSLayoutAnchor](https://developer.apple.com/documentation/uikit/nslayoutanchor)  
ここに説明があるように、`NSLayoutConstraint`を直接使うのではなく、`NSLayoutAnchor`を代わりに使ってください。（ここではご質問に直接回答していませんが、おそらくこの方針でコードを書き直せば、不具合もなくなるのではないかと、楽観的な予測をしています）

以下のサンプルコードは、幅240、高さ80の`theView`を画面底部、x軸方向の中心にレイアウトするものです。

```

    import UIKit
    
    class ViewController: UIViewController {
    
        var theView: UIView!
    
        override func viewDidLoad() {
            super.viewDidLoad()
    
            theView = UIView(frame: CGRect.zero)
            theView.backgroundColor = .lightGray
            view.addSubview(theView)
    
            theView.translatesAutoresizingMaskIntoConstraints = false //この1行はやはり必要
            theView.widthAnchor.constraint(equalToConstant: 240).isActive = true
            theView.heightAnchor.constraint(equalToConstant: 80).isActive = true
            theView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor).isActive = true
            theView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        }
    
    }
    
```
