import SwiftUI

// Step 1:

/**

 1. Create state object in main view:

    @StateObject var sheetViewPresenter = SheetViewPresenter()

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

    .environment(\.sheetViewPresenterKey, sheetViewPresenter)

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

    .sheet(item: $sheetViewPresenter.activeSheet) { activeSheet in

        // in general, you don't have to check for each case. However, you can add special case and handle separately here.
        switch activeSheet {
        default:
            sheetViewPresenter.currentSheetView
        }
    }
*/

// Step 2:

/**


 Usage:

 1. Declare in any child view:

 @Environment(\.sheetViewPresenterKey) var sheetViewPresenter

 2. Present sheet view:

 sheetViewPresenter.currentSheetView = AnyView(Text("Hello"))

 DispatchQueue.main.async {

    sheetViewPresenter.activeSheet = .any
 }

 */

struct SheetViewPresenterKey: EnvironmentKey {

    static let defaultValue = SheetViewPresenter()
}

extension EnvironmentValues {

    var sheetViewPresenterKey: SheetViewPresenter {
        get { return self[SheetViewPresenterKey.self] }
        set { self[SheetViewPresenterKey.self] = newValue }
    }
}

class SheetViewPresenter: ObservableObject {

    enum sheetType: String, Identifiable {

        case any

        var id: String {
            rawValue
        }
    }

    @Published var isSheetViewPresented = false
    @Published var currentSheetView: AnyView? = nil
    @Published var activeSheet: sheetType? = nil {
        willSet {
            isSheetViewPresented = newValue != nil
        }
    }
}

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