What Albert said plus… At a technical level: Swift’s debugPrint(…) and print(…) default to printing to stdout. When you launch an app as a user would — from the Home screen on iOS, from Finder on the Mac, and so on — the system connects stdin, stdout, and stderr to /dev/null. For a lot more links and information about the system log, see Your Friend the System Log.
