I can attest that the quality in this domain has greatly improved over the years too. I am not always fan of the quality of the Swift code that my LLM produces, but I am impressed that what is often produced works in one shot, as well. The quality also is not that important to me because I can just refactor the logic myself, and often prefer to do it anyway. I cannot hold an LLM to any idiosyncrasies that I do not share with it.
