When the words Apple and Cloud come together I start to twitch.
It’s done to death that their web services are of dubious quality, and they have got better. However you don’t have to go very deep or use services for very long to find some very sharp edges.
Maybe I'm just seeing what I want to see, but I get the impression that Apple's approach to developing products can lead to very good highs but pretty poor lows considering the amount of money they could easily invest, I would also be somewhat hesitant with an Apple Cloud unless they had something actually new to bring to the market other than basically rent-seeking for people who want to develop (say) CI pipelines for their products.
