I left iOS/MacOS development a few years ago for the same reasons. It was never ending soul sucking battle with AppStore reviewers' bs, bureaucracy, everbroken tools (in order to develop for new iOS you have to update xcode, which requires updating macos, go buy a new macbook that supports it), total absence of CI/CD, troubles with testing, the list goes on, and on, and on. I hated it, eventually moved to backend development and never looked back.
