Chiming in in case the Xcode team monitors these forums. My team is nearly unable to work because of Xcode 13 slowness. Files takes upwards of 10 seconds to open. The cursor lags behind typing. About 10-20% of our time is spent watching the mouse cursor beach ball. I'm left reeling at how shipping something like this is even possible -- the same people shipping the software are using it as well. We're having to reconsider our entire dev toolchain, and ultimately, platform choice as a result (we're using Swift on linux).
