If there were a single pinned page "Is my question on-topic or off-topic" that listed examples of on-topic and off-topic questions and explained the reasons as well as pointing to other forums for the off-topic questions that would prevent some of the off-topic questions. It could also more easily be the response to off-topic questions.
Look at this thread: https://forums.swift.org/t/problem-xcode-emulator/37843 OP got angry when told (politely) that his question was off-topic. How is he supposed to know? His question probably agrees with that brief description of Using Swift.
