Building SimTag: A Deep Dive Through macOS Window APIs, CoreSimulator, DerivedData, and Git

Modern iOS development makes it very easy to lose track of what's actually running in the Simulator. It’s common to have multiple Claude sessions open at once, a few git worktrees or clones checked out side by side, and several Simulator windows on screen as a natural
