我在PopupView中的PopupType枚举中使用了标题和说明computedProperties 。动画是offset，为什么Text会出现得更晚？

主视图：

VStack(spacing: 30) {
                            Spacer()
                            Button {
                                authManager.popupType = .warning(title: "Are you sure ?", desc: "Do you wanna sign out ?")
                            } label: {
                                Text("Sign Out")
                            }
                        }
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .padding(.bottom, 16)
                        .overlay {
                            PopupView(
                                firstButtonTitle: Constant.okButtonTitle,
                                actionButtonTitle: Constant.goBackBtnTitle,
                                status: $authManager.popupType)
                        }

弹出类型：

enum PopupType: Equatable {
    case none
    case warning(title: String, desc: String)
    case success(String)
    case error(String)
    
    var icon: String {
        switch self {
        case .none:
            return "circle"
        case .warning:
            return "exclamationmark.circle"
        case .success:
            return "checkmark.circle"
        case .error:
            return "xmark.circle"
        }
    }
    
    var title: String {
        switch self {
        case .none:
            return ""
        case .warning(let title, _):
            return title
        case .success:
            return "Başarılı"
        case .error:
            return "Hata"
        }
    }
    
    var description: String {
        switch self {
        case .none:
            return ""
        case .warning(_, let desc):
            return desc
        case .success(let desc):
            return desc
        case .error(let desc):
            return desc
        }
    }
    
    var iconColor: Color {
        switch self {
        case .none:
            return .clear
        case .warning:
            return Color(uiColor: .orange)
        case .success:
            return Color(uiColor: .green)
        case .error:
            return Color(uiColor: .red)
        }
    }
}

弹出视图：

        case dismiss
        case custom
    }
    
    var showActionButton: Bool = true

    var actionButtonTitle: String = ""
    var actionType: ActionType = .custom
    @Binding var status: PopupType
    var onAction: (() -> ())? = { }
    @Environment(\.dismiss) var dismiss
    var body: some View {
        VStack {
            Spacer()
            VStack(spacing: 16) {
                Image(systemName: status.icon)
                    .resizable()
                    .frame(width: 50, height: 50)
