Right, which is the point of the post I originally replied to and also my point. They cannot use that DevOps pipeline to build iOS apps, sign iOS apps or deploy to the Apple App Store. Shopify detailed the hoops they had to jump through a few years back (https://shopify.engineering/scaling-ios-ci-with-anka https://shopify.engineering/scaling-ios-ci-with-anka) where they specifically say that CI for iOS has to be done entirely differently to the rest of their infrastructure: It’s the only piece of infrastructure at Shopify that doesn’t run on top of Linux. We can leverage the same Google Cloud infrastructure we already use in production for our Android build nodes. Unfortunately, Cloud providers such as Amazon Web Services (AWS) and Google Cloud Platform (GCP) don’t provide infrastructure that can run macOS. You benefit from using these tools almost immediately when you're >1 developer and that's where XCode Cloud may be helpful, the 1-5 developer team size. But you're still in trouble if you are using something like React Native/Flutter/Kotlin to build iOS and Android apps and don't want to maintain separate CI processes.
