Swift Playgrounds - If you have a Mac or iPad, you can download and use Apple's gamified coding app for free, which makes it really fun and simple to learn Swift. This is a good entry point for coding even if you don't plan on using Swift long-term, as it'll help you build the logic and notation mental muscle needed across programming languages. There are lots of other free coding games and simulators with more direct real-life uses (like Tinkercad) but nothing I've used before drew me in quite like Swift did.
