This guide is going to explain how to add a Context Menu to a view in SwiftUI.
What is a context menu?
A context menu is a collection of buttons that can trigger an action. Usually, a context menu is triggered by long pressing on an item on screen in iOS/iPadOS or right-clicking in macOS. It can be used for subsequent actions on a button or item.
The picture above is an example of a context menu in my iOS app, iHog.
How to add a context menu?
To add a context menu, we are going to be using the
contextMenu() modifier and passing it
Button()s to display.
Here’s a basic SwiftUI view with a Text view that has the font color set to red.
I made the font color a variable so that we can change it with the context menu.
To add a context menu to the
Text(), add the modifier
contextMenu() like below.
This will produce the error
Type of expression is ambiguous without more context since there are no buttons inside the
ContextMenu. Let’s add a button to change the font color.
By adding the two buttons, we now are able to long press on the text and change the color, as you can see in the GIF below.
In the first picture, the menu contains icons. These can be added into the
Button() by wrapping an
HStack around the Text and the image. Now, let’s do that.
Apple provides icons to use in your apps with SF Symbols.
That’s how you make a context menu in SwiftUI!
