swift - 使用核心数据获取请求时，Xcode 错误提示 "cannot find type ' TestModelCoreData' in scope，但它编译并运行

Question

下面的代码是我的观点，我正在处理核心数据，但它不断给我错误，即它在范围内找不到实体，但应用程序运行良好，一切都得到了保存和提取。
Here are screenshots of the errors it gives

import SwiftUI

struct ContentView: View {
    @Environment(\.managedObjectContext) var moc
    @FetchRequest(
        entity: TestModelCoreData.entity(),
        sortDescriptors: [
            NSSortDescriptor(keyPath: \TestModelCoreData.name, ascending: false)
        ]
    ) var entities: FetchedResults<TestModelCoreData>
    
    var body: some View {
        VStack {
            Text("Hello, world!").padding()
            
            Button(action: {
                let newEntry = TestModelCoreData(context: self.moc)
                newEntry.name = "New name"
                
                if self.moc.hasChanges {
                    try? self.moc.save()
                }
            }) {
                Text("Add entry")
            }
            
            List(entities, id: \.self) { entity in
                Text(entity.name ?? "Unknown")
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
