Button Responsiveness Problems in SwiftUI Apps After Upgrading to iOS 18

I've been encountering significant issues with button responsiveness across my entire SwiftUI application after upgrading to iOS 18. While everything worked as expected on iOS 17, buttons across various views now sometimes fail to respond to initial taps and require a long press to trigger actions.

Here is a sample of a button within a toolbar, similar issues are occurring with other buttons throughout the app:

.toolbar {
    ToolbarItem(placement: .topBarLeading) {
        Button(action: {
            DispatchQueue.main.async {
                navigationCoordinator.pushScreen(.account)
            }
        }) {
            Image("User")
                .resizable()
                .scaledToFit()
                .frame(width: 24.5, height: 24.5)
        }
    }
}

Expected Behavior: All buttons in the application should respond to a simple tap without requiring additional user effort, maintaining consistency with their behavior on iOS 17.

Actual Behavior: On iOS 18, the responsiveness of buttons throughout the application is inconsistent; sometimes they react to a simple tap, and other times they only respond to a long press. This erratic behavior disrupts the user experience and hinders basic app functionality.

I am looking to understand whether this is a widespread issue with the new OS version and if there are any fixes or patches anticipated from Apple. Thank you for your assistance!

I have been having this issue when I build an app for work since using Xcode 16/16.1. If I build it with Xcode 15.4, there is no issue. I'm glad that long pressing works but agree it isn't ideal. I'm hoping for a fix as well. If I press other buttons or textfields that work, sometimes the unresponsive buttons may come back but others may break. Edit: My devices (iPhone and iPad) are running their respective 18.1 beta 6 OSes but has been an issue since only since building with Xcode 16/16.1 betas.

I'm still encountering the same error and hoping they will fix it soon I think you can replace your buttons or onTapGesture with .highPriorityGesture(TapGesture().onEnded({ _ in }) to see if it resolves the issue.

I am also facing this issue if I build the app on Xcode 16 and run it for iOS 18 device/simulator. The issue with responsiveness is only happening on 1 particular screen. I have checked the view hierarchies, any deprecated methods but nothing seems to clarify why its working on iOS 17 but not iOS 18

on iOS 18+, parentView's tapGesture may block childViews' tapGestures (.onTapGesture, or Button's action) -> solution: replace parentView's .onTapGesture with .simultaneousGesture
