And, coming later in React Native 0.83, you'll be able to profile and understand your app more intuitively, with native support for the Performance panel and Network panel in React Native DevTools.

The iOS queue times for Free plan users on @expo.dev were around 4 hours at this time last week.

We increased our Mac capacity today. We're seeing <10 min queue times right now. ⚡

Subscribers are seeing 0 min queue times.

Haha, yeah. Though in RN you don’t need to care about Xcode warnings. The RN team is doing a fantastic job keeping you away from any issues.

Also I’d recommend to use Expo as much as possible to reduce the amount of Xcode in your dev flow even more.

Haha, so it’s not just me! 😄

Also React Native used that shortcut for refresh until Apple started using it for recording a few years ago. But even though it’s been a while, it’s somehow still burned into my muscle memory 😅

11.86 GB – looks like video compression is doing a great job 😁

When you get back after the weekend and find out your iOS simulator has been screen recording ... since Wednesday 🤣
iOS simulator toolbar with the screen recording icon highlighted in blue, indicating active recording.

Expo is amazing! I was actually referring to the bit about apps feeling off.

Shaders are awesome! Looks great.

Did you build this with Skia or something else?

Would love to hear what stood out to you in particular.

In my experience, it’s usually not so much about the technology itself, but more about the level of detail that went into the project.

One workaround might be to initially render the WebView with opacity: 0 for the first few ms and set it back to 1 after the flicker.
Not ideal, I know. Just thinking out loud here.

Mmhh, I remember having a similar issue a while back.
In that case, the problem was actually inside the web content: it showed a white screen until the client-side rendering kicked in and set a dark background color.

Very cool! Interesting use case.

Love that it’s become so easy to build helpful tools like this nowadays 🚀

Also great to see more 🇩🇪 people building with React Native / Expo!

We thought the same at first and also tried a light blue, which looked a bit off. The difficulty in this scenario is that the app already is very colorful already and we need something that stands out.

Oliver Kwast @baumstumpf.bsky.social · Aug 1
Also, this is probably the one time I built a feature where I used the color "tomato", which is my go-to dev and debug color.
But I liked it so much this time… I just kept it 😄

What do you think, does it look too much like a warning?

It’s amazing how easy it is these days to build a custom flow for over-the-air updates.

Just take the useUpdates hook from Expo Updates and wrap a nice little UI around it.

Smooth banner → update check → ready state → tap → reload.

Awesome, isn't it?

What exactly do you mean by “the build”?
Expo Go just runs the JS bundle, so there’s no native build step involved. Curious what kind of bugs you’re running into.

Really cool! That can bring a lot of value to us all.

The same idea was already great with Flipper, but yeah you know Flipper didn't really work out 😁

Does that mean EAS iOS builds will also only cost one credit then? 😜
