a couple weekends ago i handed it the basic MLB api and asked it to create some widgets for MacOS to show me stuff like league/division/wildcard standings along with basic settings to pick which should be shown. it cranked out a working widget in like a half hour with minimal input.

i know some swift so i checked on what it was doing. for a quick hack project it did all the work and easily updated things i saw issues with.

for a one-off like that, not bad at all. not too dissimilar from your example.
