Fun optimization: when you open an app on an iPhone, the OS has a hardcoded check for if it’s the camera app, and if so, grants it its own special memory pool (“secluded memory”) for faster start up times: github.com/apple-oss-distrib…

I may or may not have spent a *bit* of time this morning recreating the new iPhone Duo folding animation. I’m using the MacBook’s screen hinge sensor (found by @samhenrigold), ScreenCaptureKit, and whole load of private CoreAnimation API… 🫠

I've been awarded a $1,000 bounty and credit for a CVE (CVE-2025-46308) by Apple Security for a vulnerability that leaks sensitive user data!

Little known fact: Swift Package Manager actually has homebrew-like functionality to install CLI tools from a Swift Package with the command `swift package experimental-install` (proposed and implemented by yours truly!). Here's an example of me installing a tool called unxip

This is why the Sandbox allows apps to run on iOS whether or not they’re “detected” as malicious, but restricts and contains ALL apps from doing anything that could harm the user

It's mathematically impossible to stop malware. Due to Rice's Theorem, it's impossible to write a program that can perfectly determine if any given program is malicious. This is because "being malicious" is a behavioral property of the program.

Rust is genuinely such an unfun language to work with, just a new thing that blocks whatever you're doing at every turn, made a big mistake of writing a backend in it, next time I'll just use Swift again like always...

The package/internal API of swift framework can be easily hacked by adding it in swiftinterface. But what if you want to call some non-inlined private API directly in Swift? (Not by load/dyld stuff) The answer is _private(sourceFile:) which is also used in SwiftUI.Preview.
