If you’ve used UIKit before, many of the classes you know and love map pretty much directly to their SwiftUI equivalents just by dropping the
UI prefix. That doesn’t mean they are the same thing underneath, just that they have the same or similar functionality.
Here’s a list to get you started, with UIKit class names followed by SwiftUI names:
UICollectionView: No SwiftUI equivalent
isSecureTextEntryset to true:
UITextView: No SwiftUI equivalent
UIStackViewwith horizontal axis:
UIStackViewwith vertical axis:
NSAttributedString: Incompatible with SwiftUI; use
There are many other components that are exclusive to SwiftUI, such as a stack view that lets us build things by depth rather than horizontally or vertically.
