SwiftUI Status Bar app Issues with buttons

[mrjerryseigle]

I created a Status Bar app using the SwiftUI demo project Dad Jokes. I am targeting macOS 10.15 so I had to modify the entry point of my application. I created a SwiftUI view that has a button. The issue that I have is that sometimes the button hangs where it stop responding. Sometimes I have to keep pressing the button before it start responding to button taps. This happens when the button is connected to a function or a simple print to the console. Its seem to only happen when I use .buttonStyle(PlainButtonStyle()) on my button. Below is a sample of my application

AppDelegate.swift

import Cocoa
import SwiftUI
import RevenueCat

class AppDelegate: NSObject, NSApplicationDelegate {
    
    static private(set) var instance: AppDelegate!
    let statusBarItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
    private var window: NSWindow!
    private let menu = ApplicationMenu()
    
    func applicationDidFinishLaunching(_ aNotification: Notification) {
        AppDelegate.instance = self
        
        DispatchQueue.global().async {
            // Initialize RevenueCat (Purchases)
            Purchases.logLevel = .debug
            Purchases.configure(withAPIKey: Constants.apiKey)
        }
        
        // Setup app to run in the status bar
        statusBarItem.button?.image = NSImage(named: NSImage.Name("ELMC"))
        statusBarItem.button?.imagePosition = .imageLeading
        statusBarItem.button?.image?.isTemplate = true
        statusBarItem.menu = menu.createMenu()
    }
    
    func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool {
        return true
    }
}

ApplicationMenu.swift

import Foundation
import SwiftUI

class ApplicationMenu: NSObject {
    
    static let shared = ApplicationMenu()
    
    let menu = NSMenu()
    var settingsWindow: NSWindow!
    
    func createMenu() -> NSMenu {
        let mainView = MainView()
        let topView = NSHostingController(rootView: mainView)
        topView.view.frame.size = CGSize(width: 250, height: 180)
        
        let customMenuItem = NSMenuItem()
        customMenuItem.view = topView.view
        menu.addItem(customMenuItem)
        menu.addItem(NSMenuItem.separator())
        
        menu.addItem(NSMenuItem.separator())
        
        let aboutMenuItem = NSMenuItem(title: "About My Remote Bridge",
                                       action: #selector(about),
                                       keyEquivalent: "")
        aboutMenuItem.target = self
        menu.addItem(aboutMenuItem)
        
        let webLinkMenuItem = NSMenuItem(title: "Contact Support",
                                         action: #selector(openLink),
                                         keyEquivalent: "")
        webLinkMenuItem.target = self
        webLinkMenuItem.representedObject = "https://codewithchris.com"
        menu.addItem(webLinkMenuItem)
        
        let quitMenuItem = NSMenuItem(title: "Quit",
                                      action: #selector(quit),
                                      keyEquivalent: "q")
        quitMenuItem.target = self
        menu.addItem(quitMenuItem)
        
        return menu
    }
    
    @objc func about(sender: NSMenuItem) {
        NSApp.orderFrontStandardAboutPanel()
    }
    
    @objc func openLink(sender: NSMenuItem) {
        guard let link = sender.representedObject as? String,
              let url = URL(string: link) else {
            return
        }
        NSWorkspace.shared.open(url)
    }
    
    @objc func quit(sender: NSMenuItem) {
        NSApp.terminate(self)
    }
}

MainView.swift

import SwiftUI

struct MainView: View {
    var body: some View {
        VStack() {
            Spacer()
            
            Button(action: {
                print("Button tapped")
            }) {
                Text("Get New Connection Pin")
                    .frame(maxWidth: .infinity)
                    .frame(height: 40)
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(4)
            }
            .buttonStyle(PlainButtonStyle())
            
            Spacer()
        }
        .padding()
        .frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .topLeading)
    }
}

struct MainView_Previews: PreviewProvider {
    static var previews: some View {
        MainView()
            .frame(width: 225, height: 180)
            .background(Color.white.opacity(0.1))
    }
}

If I remove .buttonStyle(PlainButtonStyle()) Everything works as expected but when I add it then that’s when I have the issue with freezing or hanging or the button stop responding. The application menu items work its just the Swiftui button stops. The weird thing is that I can add other elements that have user interaction and they will keep working with out issue. Its just something with the button press

I attached a video to show issue:
