Class 'hogeClass' has no initializers って出た時の対処法[Swift]

Posted at

原因

classっていちいちinit()せなダメだっけ?と思っていたところ原因はこれだった

定義してた変数がオプショナル型でなかった
nilを許して!→初期化して! ということらしい

対処

オプショナル型にする(hogehogeDelegatehogehogeDelegate?)

class hogeClass {
    
    private var delegate: hogehogeDelegate?
//private var delegate: hogehogeDelegate だとエラー出る
  
}
