The Feb 2019 update to Civilization VI added support for multiplayer “Play by Cloud” games. These are long-running asynchronous games where the save file lives on the cloud and everyone take their turn when it comes up. It’s useful to be notified when it’s your turn to keep the game moving.

Preview: I figured out how to define modules for static libraries, so you can import them into Swift or into other module-defining frameworks. This solves a common build error: “include of non-modular header inside framework module“, as it allows you to turn that non-modular header into a modular one. You just have to define a…

I recently came across this question on Twitter: Hey #swiftlang peeps: How do you create an var that holds an immutable Array? As in a var that you can assign different immutable Arrays to?— Mike R.
