我试图创建一个带有可以添加或删除的圆圈的滚动视图（在SwiftUI中使用CoreData），但当我创建新圆圈时（从另一个视图），圆圈不会出现。重新加载预览后，将显示创建的项目。然而，删除它们本身工作得很好，但它发生在视图中。
我该怎么弥补？
代码如下：

个人资料菜单

struct ProfileMenu: View {
    
    @State var circles : [Circle] = []
    @ObservedObject var vm = CircleViewModel()

    let colors2 : [Color] = ...
    let colors3 : [Color] = ...
    
    @State var showCircleInfoScreen : Bool = false
