Silver is a free implementation of Apple's Swift programming language.
Built on over ten years of solid compiler knowledge and technology, with Silver, you can use Swift to write code directly against the .NET, Java, Android and Cocoa APIs. And you can also share a lot of non-UI code between platforms.
RemObjects Silver supports four different development platforms.
Think of it not as "cross-platform development", but as Swift truly and natively supporting each of these platforms as a first class citizen and development solution.
Learn more about each platform below:
“Echoes” is the name for Elements' support for the Microsoft Common Language Runtime (CLR), also often referred to as .NET.
Elements lets you write apps for all flavors of the CLR, from the standard .NET Framework, over the open source Mono and Xaamrin platforms, to WinRT for Universal Windows apps, and even Silverlight. Of course Elements also supports ASP.NET for web development, as well. This website itself is implemented in Oxygene using ASP.NET.
No matter what language you choose, you have full access to the .NET class libraries, and you can seamlessly reuse any existing .NET libraries out there – from third parties to open source. And the executables you create will be pure .NET.
“Echoes” is our platform of choice for creating Windows apps, websites, and cross-platform servers and command line tools via Mono.
The “Cooper” platform encompasses Elements' ability to build apps for the Java Runtime (JVM).
This lets you build apps for every place that Java can run – from PCs to embedded devices, and of course includes extensive support for today's most relevant use of Java: creating native Android apps.
No matter what language you choose, you have full access to the standard Java class library and (on Android) all the standard Android libraries. You can also seamlessly reuse any existing Java and Android libraries (
.aars) out there – from Google Services over third parties to open source components. And the executables you create will be pure cross-platform Java byte code.
“Cooper” is our platform of choice for creating Android apps.
Under the “Toffee” platform, Elements lets you build native apps for the Apple platform, via Cocoa. This encompasses iOS, macOS, tvOS and watchOS.
Elements lets you create apps for all four of Apple's platforms, using the native Cocoa APIs and compiling to CPU-native code for the respective platforms (64-bit Intel for macOS, and 32-bit and 64-bit for iOS and its siblings).
No matter what language you choose, you have full access to the Cocoa class libraries, from Foundation up to AppKit/UIKit and all the frameworks Apple provides. And you can seamlessly reuse any existing Cocoa libraries out there – from third parties to open source, simply by importing their headers.
“Toffee” is our platform of choice for native apps for the Apple platform, including iOS, macOS and tvOS.
“Island” is the newest Elements platform, introduced with Elements 9.
Since we started Elements with just a single language (Oxygene) and a single platform (.NET) back in 2004, users have begged us to add support for creating CPU-native Windows executables, as well. Island offers that, and adds native Linux and Android NDK support to the mix, as well.
No matter what language you choose, you're able to create native apps and libraries for Windows (32 and 64-bit Intel) and Linux (64-bit Intel and ARM). You have full access to the platform's native C-level APIs such as the "Win32" API on Windows, and
glibc on Linux, and you can link to any existing libraries by importing their C headers.
Island also comes with its own minimal RTL and basic class library that gives you an object system, native String and collection types, and more.
“Island” is our platform of choice for creating small Windows and Linux utilities and server apps, and to implement highly-efficient bits of code to be embedded in .NET based Windows apps.
RemObjects Silver provides you with two choices for your development environment, depending on whether you work on Windows or the Mac. And with Water, we have an exciting third option for Windows coming, later this year:
If you develop on Mac, you will love Fire, our Mac IDE for Elements.
Three years in the making, we first introduced Fire in 2016, and it has instantly become a favorite among our users. With the latest Elements 9.1, Fire has gotten even better, and we're not stopping.
Fire was designed from the ground up to be a great Mac app, to be fast and lean, and to focus on letting you get your job done well. It is responsive, unobtrusive, yet vastly powerful with a sophisticated code editor, great debugger support and an innovative navigation model.
Fire also supports development for all of the Elements platforms, including .NET, Java and native Windows and Linux apps, right from your Mac.
If you're a developer on Windows, we've got great news for you!
Later this year, everything that is great about Fire, our lean and mean IDE for the Mac, is coming to Windows in the form of Water.
Water is the essence of Fire, re-imagined for the Windows environment. It takes our work from Fire for re-thinking what a modern and productive IDE experience should look like, and applies it to Windows. It's not a simple "port" or a cross-platform IDE, it is Fire, truly re-designed around a Windows-first developer experience.
Just like Fire, Water supports development for all of the Elements platforms, including .NET, Java, Cocoa and native Windows and Linux apps, right from your Windows PC. And Water co-exists with Visual Studio, so you can work with the same projects in any of our three IDEs.
Read more about Water, its development process, and when it will be available.
If you develop mainly on Windows, Elements integrates into Visual Studio, the open IDE from Microsoft which provides a sophisticated and extensive developer experience, including visual designers for creating Windows GUI apps in WinForms and WPF, and for ASP.NET.
Elements comes with its own copy of Visual Studio 2015, so you don't need to own or purchase a separate license – but if you already own and use Visual Studio 2015 or 2017, say with Visual C#, Visual Basic or Visual C++, then Elements will integrate right into that copy.
Even on Windows and in Visual Studio, Elements supports development for all platforms. For debugging and testing Mac, iOS, tvOS or Island-based Linux apps, Elements will seamlessly connect to your Mac or Linux machine via our CrossBox technology.
Whether on Mac, WIndows or even Linux, you can use your favorite external editor and Elements' command line build chain to work on and build your projects.
Elements 9 lets you use msbuild/xbuild or the standalone
Elements.exe command line compiler from terminal, your automated build scripts, or even friggered from within your favorite text editor.
Currently in beta and shipping later with Elements 10, there is also
ebuild, our new cross-platform opensource build chain that we're movig all Elements lagauges and platforms over to.
Silver in Action
The free "Community License" allows you to use release versions of Silver for all platforms and for any purpose – including commercial projects – at absolutely no charge.
The "Community License" version is provided "as is", and unsupported.
If you would like to help support the development of Silver, and all of the Elements eco-system, we hope that you will consider purchasing a paid "Full" license for Silver or the whole Elements package (with all four languages).
A Full Silver or Elements license gives you several benefits:
In particular the access to pre-release builds is a significant plus; our pre-release builds are usually production-stable(ish), and allow you to experience and help shape new features and benefit from the latest bug-fixes.
For Swift in particular, pre-releases give you early access to new language features as Swift evolves – often even before Apple Swift has implemented new proposals, itself & ndash; and lets you be on the cutting edge with, right now, Swift 4 and 5.
Your patronage is much appreciated.
