The action of tapping a button triggers the function “did tap app icon,” allowing for the changing of the app icon based on the button’s tag. The code snippet also introduces how to define app icons in the info.plist file and talks through the structure of the CFBundleIcons dictionary. Additional icons can be added by following a similar format in the plist file.

In this segment of the video, the speaker demonstrates changing app icons in a UI application. They show how to set icons for Facebook, Uber, and Google using PNG files, noting that JPEGs may not appear correctly on buttons. The process involves editing the view controller, setting up tags for each app icon, and updating the info plist accordingly. The speaker runs the app to show the changes, emphasizing the importance of using PNG files for app icons to ensure they are displayed correctly.

In this segment of the video, the speaker explains how to have multiple app icons by making simple entries in the info.plist file and using the function off of UIApplication.shared to set alternate icon names. The icons should be PNGs in the project itself, not in the xcassets. This feature allows for offering different icons for light and dark modes, themes, or even hiding easter eggs like the original Instagram icon. It is considered a gimmicky but engaging feature that users appreciate. The speaker urges viewers to like, comment, and subscribe for more content.
