View Original View Raw

Summary

SwiftUI continues to be a rapidly evolving platform with many updates for iOS 17, including advanced scroll view effects, container relative sizing, and Metal shaders. WWDC23 is offering 50% off all books and bundles to celebrate the new updates. Some of the new features include scroll view improvements, drawing and animation improvements, in-app purchases, inspector for views, haptic feedback, and color values from Color. There is also improved API for filling and stroking shapes at the same time, and new support for rounding some corners of a rectangle. Lastly, SwiftData is a dramatic and wide-ranging change to data management that is welcomed, but needs to be researched before writing about it.
