I have (had) the same issue as sfcoder describes. I recently purchased an M4 Pro, which is great as to the hardware, but not so great as to the forced development path. The M4 Pro meant a new OS (Sequoia), followed by a new requirement (XCode 16.3), and so forth and so on. As noted by bitsflew, NoHopeNoTop, raahimkhan_, and filipslepcev, downgrading to iOS Simulator 18.3 (from 18.4) did the trick. Fyi, my new hardware meant I could not move backwards to Xcode 16.2, as recommended by filipslepcev; and my particular code stack meant I could not try changes in session values, as recommended by kuba.libre. Otherwise, changing from 18.4 to 18.3 was all I needed. Cost me six weeks to find that answer, having traveled thru many a rabbit hole.
