SwiftUI:正在等待变量为true

Question

这是我的代码

struct Home: View {
@State var status = UserDefaults.standard.value(forKey: "status") as? Bool ?? false
var userEmail = Auth.auth().currentUser?.email
@State private var hasTimeElapsed = false
var body: some View {
if self.status {
while (idkisrun == true) {
if group_array.contains(userEmail ?? "1") {
HomeScreen()
} else {
Verify()
}
}
} else {
VStack{
Login()
}

这是错误

error: closure containing control flow statement cannot be used with result builder 'ViewBuilder'
while (idkisrun == false) {
^
SwiftUI.ViewBuilder:2:30: note: struct 'ViewBuilder' declared here
@resultBuilder public struct ViewBuilder {

如何修复此问题，以便能够等待变量为true，然后继续执行代码？

尝试制作"idkisrun"；作为已发布变量(如果不是(。然后尝试将(while(运算符更改为(if(。它应该有效。此外；idkisrun"；应仅在主踏板中更改以更新视图。希望它能有所帮助，祝你好运！(
