Swift CoreData数据未显示在我的列表视图中

我对CoreData有一个问题…我已经设法让它工作，但它不会显示我的标题属性（即任务名称）。这方面我还不太熟悉，希望有人能帮我

它看起来像是在您的

CellView

中没有关闭switch语句，这可能会导致您的文本仅在选中复选框时显示。（

completionState

为true）将包含标题的文本置于switch语句之外：

HStack {
    switch completionState {
    case false:
        Image(systemName: "square")
        
    case true:
        Image(systemName: "checkmark.square")
            .foregroundColor(.green)
    }
    
    Text(title)
        .foregroundColor(.black)
}
