Continuous Integration

I was wondering if anyone has set up ci for a kotlin kmm application before. I have done circle ci with a pure kotlin android project but this would be my first experience with ios as well. I have looked into Circle Ci but I wouldn’t know how to get that started since there is only the one config.ym and I can’t see how that could be shared for two buildsl. Has anyone else configured a kmm app successfully? Would love to get other people’s insight!
