I would not be surprised if the percentage of Apple's code that is in Swift is more or less the same percentage of Google's code using Golang (with Golang having a slight advantage maturity wise). That could be true, but what it's being used for is perhaps more important than the percentage. Not to underestimate the importance of a calculator, but it is known that Google uses Go in: - dl.google.com - Kubernetes - Youtube's MySQL scaling infrastructure (Vitess) - Google's mobile data compression proxy (Flywheel) Of course, Go's first stable release was in 2012, so Swift still has some time to catch up ;).
