This means that you can use Swift for free, for any purpose, without any royalties or licensing fees. You can also modify and redistribute Swift, as long as you keep the original copyright and license notices.

The Runtime Library Exception allows you to use the Swift standard library and runtime libraries in your own projects, even if those projects are not licensed under the Apache 2.0 license. This makes it easy to use Swift with other programming languages and frameworks.

The Swift license is designed to be permissive and open, so that anyone can use Swift to build great software. If you are interested in learning more about the Swift license, you can visit the Swift website.
