使用未解析的标识符 [英] Use unresolved identifier

问题描述

我的应用程序工作正常，现在突然Xcode给了我这个错误：

My app was working fine and now suddenly Xcode is giving me this error:

使用未解析的标识符卡删除

use unresolved identifier cardWasRemoved

func addNewCards() {
    countOfCards = countOfCards-1
    if(countOfCards >= 0){
        self.arrayAuthorization.remove(at: dm.objectIndexToRemove)
        cardWasRemoved(removeIndex: dm.objectIndexToRemove)

    }
}

我的方法实现如下：

open func cardWasRemoved(removeIndex:Int) {
    if layout.newCardShouldAppearOnTheBottom {
        layout.cardDidRemoved(removeIndex)
    } else {
        layout.cardDidRemoved(removeIndex)
    }
}

推荐答案

它可能是Debug构建配置有一些工件（当你尝试在模拟器上运行时），而你没有这些artifac ts用于发布配置。尝试删除DerivedData目录：如何删除Xcode 8中的派生数据？

It might be that there are some artifacts for the Debug build configuration (when you try running on a Simulator), and you don't have these artifacts for the Release configuration. Try removing your DerivedData directory: How to delete derived data in Xcode 8?
