Tangent to this but Swift is slow in surprising ways: json decoding and decoding strings into date objects are insanely slow. Both are common operations for an iOS app (eg client/server app that decodes a json encoded payload) and I have no idea why not solved years ago. Another surprise is that Apple’s protobuf generator is able to produce iodiomatic Swift, the same is not true for Kotlin :)
