I have to admit to the same suspicions over the years, but then the question is: what supported/reliable solution will they implement for iOS development? Sure, there are options for developing to the iOS platform outside of X Code/macOS, but something better would have to be introduced before EOLing macOS. Do they simply introduce macOS as an independent operating system and/or license vendors to produce hardware to a certain specification?
