Apple has done a lot of work with widgets in recent years. A new class of SwiftUI-based iPhone widgets debuted in iOS 14, were added to in subsequent years, became interactive in iOS 17, and have made their way to the Lock Screen, StandBy, and more.
But as the new widgets have evolved, Apple’s old widget system has continued to live on. All the way through iOS 17, you could use legacy widgets as part of your iPhone’s ‘Today’ view.
That’s changing in iOS 18, which officially ends support for legacy widgets on your devices and will disable them once installed.
