Android automation took 90 minutes by exploiting Chrome DevTools Protocol via ADB-forwarded WebView sockets. iOS took over six hours due to compounding Simulator restrictions: no CDP access, broken clipboard/keyboard input for email fields, undismissable native permission dialogs requiring direct TCC.db writes, and coordinate system mismatches requiring accessibility API probing to resolve. The post also covers an agent discipline failure where Claude committed unrelated in-progress changes to production, causing cascading test breakage. Key lessons: prefer CDP over UI taps, measure UI coordinates via accessibility APIs rather than guessing, respect git worktree isolation, and run tests before pushing. ## Full article daily.dev links to this article rather than hosting it.
