我有这样的代码,它有 @FetchRequest 加载联系人然后我计算了基于 @State 变量进行过滤的属性

 @FetchRequest var fetchRequest: FetchedResults<Contact>

    private var contacts : Array<Contact> {

        Array(fetchRequest).filter { contact in
            if self.sectionSelection == 1 {
                return contact.type == "person"
            } else if self.sectionSelection == 2 {
                return contact.type == "company"
            } else {
                 return true
            }
        }
    }

@State private var sectionSelection : Int = 0

但是列表崩溃,索引超出范围错误!

 List {

            ForEach(0..<contacts.count) { i in

                ZStack {

                    NavigationLink(destination: ContactDetails(contact: contacts[i])) {
