Suggested approach: As always, start with a simple definition that clarifies the difference between regular ranges, then provide a practical example.
So, you might say that one-sided ranges are ranges where you don’t specify the start or end of the range, meaning that Swift will automatically make the range start from the start of the collection or the end of the collection. They are useful when you want to read from a certain position to the end of a collection, such as if you want to skip the first 10 users in an array.
