Gui Rambo

This update finally does what I always intended! 🎉

V1 had the right idea but the platform wasn't ready. visionOS 26's persistent widgets finally make my original vision possible – and the new 2D-to-3D API for photos is a cherry on top! 🤌

Please take a look! 👀

Gui Rambo (@inside.bsky.social) gave a great talk where he took a deep dive into how Liquid Glass was implemented by Apple. 💦🔎

Super interesting insights thanks to his rare skills of disassembling & reverse engineering private APIs:

Make Games Anywhere: Introducing Godot for iPhone and Xogot Lite Since the beginning of time, or at least since the launch of Xogot for iPad, developers have asked: “But can you put Godot on the iPhone?”

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.

Check the details on @josephhill.bsky.social blog post:

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!

There are a few significant changes coming with Swift 6.2.

Here are some thoughts on SE-0466. This one is about controlling the default isolation and it has some pretty big implications.

That’s probably because your old phone is running a version of iOS that doesn’t transcribe the audio message. The transcription is done by the sender, but the problem manifests itself on the recipient once it receives the message with the transcription.

TIL: /usr/bin/sips on macOS

"sips" stands for scriptable image processing system, and can be used to convert image from the command line without

"It also supports executing JavaScript to either modify or generate images" 🤯

TIL you can have a bindable declared in the body. Thanks for the tip 😄

Looks interesting, I’ll check it out. Thanks!

Are you using any specific tool to build the templates? I know nothing about email templates but I’ll have to design some soon…

[Video] Swift Argument Parser with Guilherme Rambo Insights on building a CLI for your own packages, and a hands-on example with the argument parser

In today's video we discuss command-line tools in Swift with
Guilherme Rambo @inside.bsky.social, including a hands-on refactor, and adding a CLI target to macOS apps.

Learn how to go beyond the basics of the Swift Argument Parser, using PathKit and custom types.

I’m completely useless the next day if I sleep less than 7 hours 😳

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! 😅

Xcode screenshot of the following code snippet: @available (iOS 18.2, *) private final class CameraToolImagePlaygroundDelegate: NSObject, ImagePlaygroundViewController.Delegate { }

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:

AFAIK they do not

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.

The image shows a cozy, modern workspace with a MacBook running Xcode, a monitor displaying an ARM64 virtual machine, and art supplies for creative projects like anime sketches. A dog sits by the desk, and shelves in the background hold tech books, gaming consoles, and a framed BSD mascot. The space is warm, organized, and inviting.

You can tell that I ask a lot for help with ChibiStudio and arm64 assembly 🤣

A screenshot of Apple's iOS 16.2 Product Security updates with the following text: TCC Available for: iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later Impact: An app may be able to read sensitive location information Description: A logic issue was addressed with improved restrictions. CVE-2022-46718: Michael (Biscuit) Thomas Entry added May 1, 2023

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
