This is why we should add more extensions later, to make these operations easier. ScrollDismissesKeyboardMode.interactively will begin the dismissal process when you drag the keyboard down, and you can drag up to cancel the dismiss.

UnitPoint has an initializer for custom coordinates, however, scrollTo(_:anchor:) does not behave as expected for values that are not integer. For instance, I assumed that UITextView and NSTextView scrolls in the same way (spoiler alert - they dont). I was building a swift syntax highlighter app to use for my blog posts on www.theswift.dev, and a simple SwiftUI app for macOS seemed like a nice way for me to quickly paste in multi-line code and copy the result from a second TextEditor.

Fortunately, in iOS 14, SwiftUI ends it all by gaining automatic keyboard avoidance. Waldo helps teams like Rocket Money provide bug free experiences to their iOS users while saving time. To design SwiftUI for multi-platform use, we can also add a ViewRepresentable typealias that makes platform-specific views in SwiftUI easier to define within the library. Use text and symbol modifiers to control how SwiftUI displays and manages that text.
