Run this Terminal command to upgrade/reinstall WakaTime for Xcode, and skip re-signing the Xcode app:
curl -fsSL https://raw.githubusercontent.com/wakatime/xcode-wakatime/master/install.sh | sh -s nosign
Note: Xcode disables plugins every time it updates, so you may need to run the full re-install in those cases curl -fsSL https://raw.githubusercontent.com/wakatime/xcode-wakatime/master/install.sh | sh
