There's a long interview with Rick Beato and Pat Metheny. My opinion is that among "younger" jazz musicians, Metheny has a rare gift for writing catchy melodies. He can write melodies that sound like folk songs, or like the most advanced deep jazz tunes, or both at the same time, pretty much on demand.
He said nobody teaches how to do this. You can study composition and arrangement, but they won't teach you how to create a melody. I don't know if he was implying that it can't be taught. But it's certainly valuable.
I know someone who wrote tunes on speculation, and one of his melodies was chosen as the year's jingle for a major brand. It made him enough money to pay cash for a house. Of course this was many years ago.
