  • Swift is part of Xcode. developer.apple.com/swift I don't use it so idk how many instances are supposed to run, or what size they should be.

  • @Tetsujin, thanks, but I know swift as a programming language, and I believe that this processes referring to code compilation, but why it is so large and kill the whole operating system, and how I can solve this problem ?

  • More data, I've had several crashes with Xcode 11 that seem to be related to Swift code-completion (they usually happen when I'm typing to fast for the completion to keep up), and on the last one I noticed a couple of 'swift' processes were jammed up with huge memory and ongoing CPU consumption.
