XcodeのThread 4: signal SIGABRTエラーについて

開発環境
Xcode 11.6
Swift 5.2.4

現在Xcodeで
「絶対に挫折しないiPhoneアプリ開発「超」入門」を読み進めながらカメラアプリを作成しています

実機（iPhone）で動かして見ると
UsePhotoと言うボタンを押すと

Swift
1Thread 4: signal SIGABRT //４のところの数字は毎回変わります

と言うエラーが出て止まってしまいます

Storyboardならこの記事に書いてある方法で関連付けを切れば良いとわかったのですがSwiftUIの場合どうしたら良いかわかりません
