macOS, Swift, storyboards How can I make the window active in all spaces? I could find how to do that with storyboard: Select the window > Attributes > Spaces > Can join all spaces. How can I do the same with code (activate and de-activate)

I have created a small app for macOS. I looked for information about how to submit it to the app store and read: "Build your apps using Xcode 13.1 or later…" https://developer.apple.com/macos/submit/ I have an old iMac Late 2013. Unfortunately, the last version I can install is Catalina 10.15.7, and the last Xcode I can install is version 12.4. Does it mean that I cannot publish my app? Is there any way I can submit it? Is buying a new mac the only solution? My iMac works well, and it is not easy for me to buy a new one. I would appreciate any recommendation Thank you

How to make a link when I click to a button in macOS? This works well in iOS. How to do the same with macOS:     @IBAction func button1(_ sender: UIButton) {         if let url = URL(string: "some link") {             UIApplication.shared.open(url)         }     }

Xcode 16.2 Swift 6 macOS Sequoia 15.1 SwiftUI I am a beginner. If I understand we can add buttons to the default Menu Bar but not delete them. Am I right? If you do not need most of the buttons, how do you solve that? I can add a button: import SwiftUI @main struct NouMenuProvesApp: App { var body: some Scene { WindowGroup { ContentView() } .commands { CommandMenu("Custom") { Button("Custom Action") { print("Custom Action performed") } } } } } Can I delete a Menu Button or create a new simpler Menu Bar?
