为什么核心数据无法在获取请求的任何模型中找到NSEntityDescriptions

Question

我有一个CoreData swift项目，我正在尝试从中获取数据。自从我将项目放在新的Mac上以来，它一直崩溃在这行上：

Sub RemoveDupsBetweenLists()
    Dim sht1 As Worksheet
    Dim sht2 As Worksheet
    Dim C1row As Long
    Dim C2row As Long
        Dim C2TotalRows As Long
        Dim CustID As String
        Dim NoDups As Long
        Set sht1 = Worksheets("Customers 1")
        Set sht2 = Worksheets("Customers 2")
        sht2.Activate
        C2TotalRows = Application.CountA(Range("A:A"))
        C1row = 2
        Do While sht1.Cells(C1row, 2).Value <> ""
        CustID = sht1.Cells(C1row, 2).Value
        For C2row = 2 To C2TotalRows
            If CustID = Cells(C2row, 2).Value Then            
                sht1.Activate
                Rows(C1row).Delete
                NoDups = NoDups + 1
                C1row = C1row - 1
                sht2.Activate
                Exit For        
            End If      
        Next   
        C1row = C1row + 1
        Loop
        MsgBox NoDups & " Duplicates were removed"
        End Sub

错误：任何模型中的任何NSEntityDescriptions都不声明NSManagedObject子类'Diary.DiaryItem'，因此+ entity感到困惑。您已经加载了NSManagedObjectModel吗？

我已经设置好实体，并且按预期工作，然后才能看到以下内容：

任何帮助将不胜感激！
