One thing I like to do in my free time is answer popular interview questions in creative ways. These are a couple examples that I have created over time to solve the FizzBuzz interview question in a Code Golf esque style. These solutions are intentionally hard to read so be prepared! I added comments to explain the code a little at least a little bit.
// function to check if input i is divisible by 3
This solution is also in my Swift Playground Repository
// Loop through numbers 1 to 100
