Flow's latest release is out, and you can now ship Lottie and Animated SVG Files! It's an awesome tool for UI Animations (or animations in general), it's easy to use and really powerful.
Flow is a powerhouse for motion design. Start from FIGMA, Sketch, Illustrator, Afffinity, wherever your own creative work lives. Then, export to: GIF, aPNG, aSVG, MOV, MP4, LOTTIE, iOS/Swift, Web Animations, React...
I animated 50 loading spinners in 48hrs and shipped the whole collection as an open-source github project. These are all native iOS animations, written in Swift and Core Animation.
