Xcode constantly phones home
Building StopTheMadness Pro in Xcode is usually very fast, because my project doesn't use any Swift. It's a combination of Objective-C, which compiles much more quickly than Swift, and JavaScript, which doesn't need to be compiled. However, sometimes the builds were very slow for some strange reason. Checking the…

Yes, Claude Code can decompile itself. Here's the source code
These LLMs are shockingly good at deobfuscation, transpilation and structure to structure conversions. I discovered this back around Christmas where I asked an LLM to make me an Haskell audio library by transpiling a rust implementation.
