Today we are launching Xogot for iPhone, along with a free edition.
The iPhone has been a challenging process for shrinking the UI even further.

We could have asked him to reverse engineer iPadOS so it can finally run full-fledged Xcode. But we preferred asking him to join us in Paris instead.
Folks, this October let’s meet @inside.bsky.social in Paris!

With the ability to virtualize a Private Cloud Compute node on macOS, I was wondering if it could run Doom, of course. And yes, it can! 😅

iOS developer PSA: if you're having trouble compiling your app that uses ImagePlaygroundViewController, there's a workaround. Implement the delegate on a Swift class that's not exposed to Objective-C (by making it private, for example).
Here's what my delegate class declaration looks like:

So the reason I've been unable to update my Apple Frames shortcut for the latest devices is a bug in iOS/iPadOS 18's Shortcuts app that hasn't been fixed yet.
For the past few months, the Overlay Image action has always removed the alpha transparency of a PNG.
I have no idea how to work around it.

Excited that I can finally talk about this! Last year I discovered a security issue that allowed a third-party iOS application to access a user's location without their consent/knowledge. Not a great writeup, but more details here: https://github.com/biscuitehh/cve-2022-46718-leaky-location
