How to show a menu when a button is pressed

SwiftUI gives us a dedicated view for showing popup menus from buttons, helpfully called Menu. This can be created from a simple string or using a custom view, but either way you get to send in a variety of buttons to control what you want to appear in the menu.

For example, we could create a simple button with several options like this:

Menu("Options") {
    Button("Order Now", action: placeOrder)
    Button("Adjust Order", action: adjustOrder)
    Button("Cancel", action: cancel)
}

You can also place menus inside menus if you want, which will cause iOS to reveal the second menu when the first option is tapped:

Menu("Options") {
    Button("Order Now", action: placeOrder)
    Button("Adjust Order", action: adjustOrder)
    Menu("Advanced") {
        Button("Rename", action: rename)
        Button("Delay", action: delay)
    }
    Button("Cancel", action: cancel)
}

If you wanted a customized label using some text and an icon, you could use this:

Menu {
    Button("Order Now", action: placeOrder)
    Button("Adjust Order", action: adjustOrder)
} label: {
    Label("Options", systemImage: "paperplane")
}
