Building and shipping Mac and iOS apps without opening Xcode

Use Xcode's CLI tools (xcodebuild, notarytool) and XcodeGen to automate Mac/iOS app builds, avoiding Xcode GUI entirely via scripts like release.sh. LLMs like Claude Code streamline setup, handle certificate management, and generate workflows for signing, notarization, and deployment without manual GUI steps.

The Git history command deserves more attention

The user struggles with Git's complex parallel workflows and explores jj but finds Git's new `history` commands (fixup, reword, split) promising for painless history rewriting without switching tools. While limited by merge conflicts and stateful operations, these atomic, branch-aware features reduce the need for jj's advanced conflict handling, offering incremental improvements within Git's ecosystem.
