It's condescension because you continue to refuse to believe what I'm saying, and you keep insisting that something difficult is easy.
Moreover, if I needed help with a Swift issue, I would go to my many friends and associates in the Apple developer community. In fact, I've discussed the issue with some members of the Apple Swift engineering team, and I have an open bug report that Apple hasn't addressed. The very last person in the world I would consult about a programming issue is a random, condescending HN replier.
