Swift is a programming which is mostly used to develop iOS, OS X, watchOS and additionally it is available for developing Android apps. It is considered very safe than C and Objective-C, various added features helps in easier and flexible programming. For iOS developers, it is plain sailing to use Swift instead of Objective-C. Its very easy and fast to write codes with Swift.
Apple introduced SWIFT as its World Wide Developer Conference. Swift makes use of Objective-C runtime which allows C, Objective C, C++ and Swift code to run together. Swift is also considred as the future of iOS Development.
1. Picking an IDE to start: The first thing is to determine which IDE (Integrated Development Environment) to make use of. The Swift code couldn’t be directly plugged into Android Studio. So it can be done with Xcode 6. For making Android apps by Swift, it is best for future solution to build a compiler for Swift code that could be plugged into Xcode and that compiler will be able to translate Swift into ready-t-run Java byte-code and an Android Package (APK) ready to install.
2. Swift to Java Source code compiling: To start with something to work quickly the best option is to take Swift code and compile it into Java Source code- and then it must be taken into Android development environment for finishing it building into an installable app. And then it must be tested, running it into an iPhone and then ran a customized compiler that parsed the Swift code and output Java source code (to adjust any necessary syntax, and substituting appropriate Android calls for any iOs native ones). And then it must be moved to Android Studio to finish the build process and produce Android APK.
Both Xcode and Android Studio must be there on the desktop to follow this approach. You will see a faster efficiency gain by being able to use the same base code and overall benefits of using Swift is attained by using this method.
3. Single User Interface Layer development: There is a need to have a UI abstraction or conversion layer, so something can be visible on screen. In IOS, user interface can be created by writing code that displays UI features or Interface Builder or Storyboards can be used. With Android, you can write custom code or define UI by using XML or visual layout tool.
Xamarin will help you in taking logic and carry it over across platforms, which saves a lot of time. But it also require development of 2 native Uis. Xamarin has recently introduced Xamarin.Forms which allows developers to create their UI once. This particular approach is for apps that provide the same experience regardless of platform.
You would like to take advantage of UI features specific to Android and IOS-but in this method UI had to be developed for Android withing Swift. And this is very possible, by using native IOS UI calls made in Swift, then to be translated them to corresponding Android UI calls, and it all worked very beautifully.
