The Swift project is introducing new downloadable Swift toolchain images for Windows! These images contain development components needed to build and run Swift code on Windows.
For over a year now, there has been a significant endeavour to port Swift to Windows in conjunction with the developer community at swift.
The Windows support is now at a point where early adopters can start using Swift to build real experiences on this platform. Porting Swift to Windows is not about simply porting the compiler, but rather ensuring that the full ecosystem is available on the platform. This includes the compiler, the standard library, and the core libraries dispatch, Foundation, XCTest. These libraries are part of what enables developers to write powerful applications with ease and without having to worry about many of the details of the underlying system.
There are many technical details in the story of bringing Swift to a usable state on Windows, and if you are interested in them, I would recommend checking out my talk on the topic from the LLVM Developer Conference.
With these core libraries and the flexible interoperability of Swift with C, it is possible to develop applications on Windows purely in Swift while taking advantage of the existing corpus of libraries on the Windows platforms. This demo calculator is written entirely in Swift, with code seamlessly flipping between the application code written in Swift and the system libraries:. It will soon be possible to get the application building using swift build without needing CMake or Ninja.
Here you can see stepping through the application using lldb :. Early adopters like Readdle are experimenting with cross-platform applications written in Swift, easily bringing many of the existing Swift libraries to Windows to support their applications. We at Readdle started experimenting with Swift on Windows more than a year ago, in Q2 of Despite some functionality being unready as of yet, Swift on Windows turned out to be fully satisfying our needs.
All business logic of Spark is located in a separate Core module. A pack of modules, actually, but we refer to them as Core. So, basically, we had to port Spark Core on Windows. After all initial concepts were proved, it was mostly routine day-to-day work to bring it alive on Windows. Another challenge was to decide how to implement the user interface.
After extensive discourse we ended up with Electron as the front-end part of future Spark for Windows. That meant we not only needed to be able to build Spark Core on Windows but also use it as a loadable addon for Node. That appeared to be surprisingly easy. Swift perfectly imports N-API headers. We still need three lines of C code plus one small C header to define addon entry point, but all logic is in Swift. Due to the crossplatform nature of Node.
Since the first day we started, Swift on Windows did a giant step forward in terms of platform support and stability. If you are maintaining a small Swift library — you could easily add Windows support already!
Adding support for Windows to Swift is the beginning of a journey. The current support sets the first milestone where the language is usable. There is yet another even broader part of the ecosystem like lldb and the Swift Package Manager which still need more work to be as complete in their support for this different platform.
The Getting Started section has been updated with new information about using Swift on Windows! For the early adopters who are getting started and finding issues, please report them to the Swift Bug Tracker. There are many opportunities for those interested in helping push Swift on Windows forward. One of the things that makes Swift easy to use is libraries: publishing new libraries and packages for Swift on Windows or porting existing ones is another way to get involved and help make working with Swift an ever greater delight.
For the ones interested in working on core tooling, there is plenty of work to be done to improve the debugger and to improve the Windows support in the Swift Package Manager. We invite you to check out the Swift Bug Tracker for the current issues and to send patches to the GitHub repositories. There is also a new section on the Swift forums to discuss the development of Swift on Windows.
There the community can discuss issues or you can introduce yourself and let others know what area of the tooling you are focusing on. This is the perfect opportunity to become involved in the project and help it grow into a strong, vibrant, cross-platform ecosystem. We cannot wait to see what exciting things you build with Swift!

Swift is one of the hottest languages around right now, and for good reason. Mac and iOS apps take up a huge portion of the market.
Being able to build iOS apps natively is a big deal for folks who don't want to dip into the murky depths of Objective C. Since Swift is native to Apple, you need a Mac, right? While there is no "out of the box" method to compile Swift on Windows, that doesn't mean that Windows users cannot learn Swift.
Before beginning, let's look at what Swift actually is. Swift is a programming language designed by Apple. It's a relatively young language which was released to the public in , though it is already widely regarded. The TIOBE Index of top programming languages in placed Swift at number 11, making it one of the fastest growing languages of all time. In short, if you're programming for Mac or iOS, Swift is for you! For a more in-depth look at the uses for Swift, take a look at these reasons why Swift is worth learning.
Firstly, we are going to need an editor to write our code in. You can use any IDE you are comfortable with, though it isn't strictly necessary to use one and any text editor will also suffice. It mostly comes down to personal preference, though if you need help deciding what to use this guide may help you.
Lets get down to some coding! For our test project today we are going to create a simple program which will run on the Windows command line. We'll begin by printing a question to the screen, wait for the user to type their response, and then use this response to provide an answer.
This will display when the program runs. Now that we have asked a question, we should provide a way to let the user answer. For this, we use the readline method and store the answer as a variable called response. If you're already familiar with other programming languages you may notice a few small differences here. Firstly, we can store the data acquired from readLine as a var instead of having to specify that it is going to be a string.
Another change for those of you coming over from JavaScript or C is the lack of semicolons to denote the end of lines. Now that we have this information stored in a variable, we want to use it and display it back to the user. What could be nicer than wishing them a great day? Even if you have experience in other languages, you will see some differences here. Another feature of Swift is the use of Optional Values. These values are hard to understand at first glance, but add greater functionality to the use of variables within Swift.
In this instance, we simply want to display the value as it is, so we add an exclamation mark after the variable name response! An optional value is a variable that may or may not get assigned a value. It doesn't require one. If it isn't assigned a value, then it will be assigned nil.
A question mark? If your menu is missing the Swift file type, select all files instead, and add the. Now that we have a program, we need to be able to compile and run it. While there is no built in way to program Swift in Windows 10, there is a work around.
Han Sangjin has created a compiler for Swift which is available for download from Github. Download and install the Swift for Windows application using the instructions provided in the link. Once it is installed, open it up. Click on the Select File button and select your previously made program. Click Compile and wait for the program to compile.
For a program this tiny it should be nearly instant, though it can take time depending on how complex you made your code! You should receive a "Successfully compiled" message in the dialog box. If not, go back and check through your code to make sure you haven't made any errors.
Once the code compile, click Run to run your program. The program will open in the Windows Command Line, and should look like this:. It is worth noting that you must use the Swift for Windows application to run your code, the EXE file that's created will not work stand alone, even if the application is open. If you decide that Swift is for you, there are a wealth of tools out there to help you.
Once you've got a basic grasp of the environment, why not try a few beginner projects to bring your knowledge to life? Here's how to create a simple Swift program and compile and run it in Windows What Is Swift?
