swift – TipGroup tip presented as sheet iOS 18 instead of a popover tip

While using TipKit’s TipGroup I encountered what I believe to be a bug:
The second tip of the TipGroup is presented as a sheet.

I’ve watch the two WWDC sessions about TipKit and the implementation looks good.

Has anyone got this issue too ? And found a solution ?

You can reproduce it when running on iOS 18 with the code below. I have the issue on simulator using iOS 18.6 and on a device using the latest iOS 18.7.1, but so far I can’t reproduce on iOS 26.

import SwiftUI
import TipKit

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            TipKitTestView()
                .task {
                    try? Tips.resetDatastore()
                    try? Tips.configure()
                }
        }
    }
}

struct TipKitTestView: View {
    @State
    var tips = TipGroup {
        Tip1()
        Tip2()
    }
    var body: some View {
        HStack {
            Text("Hello")
                .popoverTip(tips.currentTip as? Tip1)
            Text("World")
                .popoverTip(tips.currentTip as? Tip2)
        }
    }
}

struct Tip1: Tip {
    var title: Text {
        Text("tip #1")
    }
    var message: Text? {
        Text("short message inside the tip")
    }
    var image: Image? {
        Image(systemName: "eye")
    }
}

struct Tip2: Tip {
    var title: Text {
        Text("tip #2")
    }
    var message: Text? {
        Text("short message inside the tip")
    }
    var image: Image? {
        Image(systemName: "trash")
    }
}
