swift - SwiftUI：等待变量为真

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 {

我该如何解决这个问题才能等待变量为真，然后从那里继续代码？

Answer 1

尝试将“idkisrun”作为已发布变量（如果不是）。比尝试将（while）运算符更改为（if）。它应该有效。此外，“idkisrun”应仅在主线程中更改以更新视图。希望它会有所帮助，祝你好运！）
