THIS WEEK'S BLOG POST

Simulator Camera: Test your app without a physical device

It's the feature that shocked the most developers so far— how is this possible?!

It's also the feature that should've been built by Apple for years.

It's Simulator Camera support, testing camera functionality using your Mac's camera.

This is now generally available and this week's article tells you all about it.

WHAT I'M WORKING ON

A goodbye to #Pragma Conference

Pragma has been an amazing conference, with many impressive talks. One stood out: Arkadiusz Świętnicki is a sightless coder and delivered an amazing talk. If that's not enough, he also did a shoutout to Helm and RocketSim for making app development more approachable.

However — It's a sad way to end this newsletter issue — but I've been part of the last edition of #Pragma Mark Conference in Bologna. It's harder than ever to organize conferences. Costs are raising, sponsorships are more challenging to get, tickets no longer sell as fast as before.

I'm on a personal mission to find out how we can keep conferences alive. They're super important for the community, they bring us together. If you are a conference organizer or if you once tried to organize one, reply and let me know the hardest challenges.

p.s. my talk on Approachable Concurrency will be available on my YouTube channel in two weeks.

UNTIL NEXT TIME
