Until very recently I would have championed how critical it is for tools like this to be native apps but honestly Figma has proven that wrong, it just blows Sketch completely out of the water in terms of performance, stability and collaboration.
To make matters worse Apple just doesn't offer a machine powerful enough for the 3D part of my work, even if I spent $7000 with Apple I'd still get significantly better performance paying around $3000 for a PC build so Figma is a godsend working across all the platforms I use and all the platforms my coworkers use.
This pitch seems even more surreal as Apple moves away from MacOS, these technologies that the Sketch team are talking about being so important are clearly considered the past by Apple and technology like catalyst being the future. I honestly can't shake the feeling that a not insignificant part of Apple considers the future of the Mac as the place you go to run multiple iPad apps and because of that the technology Sketch is built with will eventually be discontinued within 10 years.
Not to mention, they've had 4 years since Figma's launch to know they need a collaboration feature shipped, it's been "Coming Soon" for years now. I actually presumed they were just doing a full webtech rewrite but judging from this it's just that writing those kind of features into a native app is a gigantic task.
Really a professional tool in 2020 that doesn't have Google Docs style collaboration is a broken tool, it's very difficult to work with remote workers without having presence within the documents.
