SwiftUI isn’t native and here’s why SwiftUI apps may sometimes feel janky. It ditches the key element that made animations run so smoothly on iOS since the original iPhone: Core Animation.

We published new beta of react-native-ide today with a huge number of updates. One frequent issue was with the simulator getting a bit choppy. We found a way to speed the processing up 5x (with more updates incoming). Testing it with new useVideo hook from react-native-skia

The iOS Simulator has never had a camera. SimCam fixes that! Your simulator can use front, back or both cameras, each with its own source you control from the menu bar.
