It depends on what you want to do. * If you want to be able to generate native Windows binaries with Swift than yes, it will take some time to build the tools (because Swift is not officially supported on Windows). * If you just want to be able to learn and try Swift there is a simpler approach if you have Windows 10: 1. Install Windows System on Linux (WSL). 2. Go to swift.org and follow the instructions to install the latest binaries for Swift 4. Use the Ubuntu 16.04 instructions (this will work in a WSL window). You don't need to build Swift from sources in this case. 3. Use Swift under WSL.
