The Tuist support for the Xcode compilation cache is out!
The video I recorded to showcase setting the cache up is literally three minutes – that's how fast you can improve your build times by up to 50 %. What's not to like? 😄

There's no better way to build empathy with building for Apple platforms than having to go through the App Store review 😂
But, finally, Tuist is available on the App Store. If you wanna see it in action, I recorded a quick video showcasing its main features: videos.tuist.dev/w/dYZAKZqx75...

I'm having a lot of fun working on the Tuist iOS app – you'll soon be able to see your latest Tuist previews and download them directly from the app.

You'd think that any PNG file would actually align with the PNG standard. But no, a long time ago, Apple decided they would hijack the PNG file and make it "iPhone-optimized": and, for example, flip red and blue pixels: marekfort.me/blog/iphone-...

Do you know that when you go to tuist.dev, there is *no* cookie popup? These cookie popups are a *choice*. Businesses don't have to have these - unless they want to track you across sessions.

We're really excited about this one. For a long time, it has been way too difficult for organizations to measure and optimize their build times.

I feel really good about the foundations we're building - as the codebase grows, it feels *easier* to implement new features, not harder.
Wouldn't it be great if you would get the bundle size difference directly in your PR?
With the new Tuist GitHub app, you can catch regressions in your bundle size _before_ they even get into your main branch.

wooahh Figma's new Sites thing produces no semantic HTML at all. Every single element is a div. Incredibly inaccessible
