Having developed shipping apps in swift 1.0, using GCD, it wasn’t any more awkward than using GCD with objective C, indeed generally it was easier because Swift is more concise. I guess in relation to your original statement, I am refuting it. They had a strong solution which was pretty easy to use, and as good as the language they were replacing, and well integrated with the platform. The idea that they ‘didn’t have a strong solution’ doesn’t really hold from my point of view. It was strong, and working which gave them the luxury of time to develop an idiomatic solution as the language matured. If there really hadn’t been a strong solution in place, I would have agreed with you.
