import SwiftUI

// Step 1:

/**

 1. Create state object in main view:

    @StateObject var universalAlert = UniversalAlert()

 2. Attach .environment(_ key:...) to main view:

    .environment(\.universalAlertKey, universalAlert)

 3. Attach alert(...) to main view:

    .alert(isPresented: $universalAlert.show) {

        universalAlert.alert
    }
*/

// Step 2

/**


 Usage:

 1. Declare in any child view:

    @Environment(\.universalAlertKey) var universalAlert

 2. Present alert:

universalAlert.alert = Alert(title: Text("Title"),
                             message: Text("Message"),
                             primaryButton: .default(Text("Primary"), action: {

}),
                             secondaryButton: .cancel(Text("Cancel"), action: {

}))

universalAlert.show = true

 */

struct UniversalAlertKey: EnvironmentKey {

    static let defaultValue = UniversalAlert()
}

extension EnvironmentValues {

    var universalAlertKey: UniversalAlert {
        get { return self[UniversalAlertKey.self] }
        set { self[UniversalAlertKey.self] = newValue }
    }
}

class UniversalAlert: ObservableObject {

    @Published var show = false
    @Published var alert: Alert!
}

I'd love to hear your feedback on this approach.
