+A busy two weeks: the long-awaiting Swift 5 was released, alongside Xcode 10.2.
+It took a while, but it is awesome to see this great release come to life.
+
+Furthermore, Swift 5.1 is already being worked on, and there are _tons_ of
+proposals ongoing, so you can expect a lot more interesting things to come!
