Xcode

Xcode is where a lot of Apple development starts, and it is also where a lot of it grinds to a halt over something small. This section gathers the tips, fixes, and notes I have picked up while building with it, so the next time the toolchain fights you, there is a clear way forward. I focus on the practical moments rather than a full tour of the IDE. One example is the fix for the maddening error where Xcode unexpectedly did not find the new dependency in the package graph, a message that can block a build for reasons that have nothing to do with your code. Another walks through installing macOS as a virtual machine, which is perfect when you want a clean, disposable environment to test an app, try a beta, or reproduce a bug without touching your main setup.
