Too Long; Didn't Read
If you come from native development background, you might be aware of a feature that both Android Studio and XCode provide to create different applications from the same code. These are known as flavors in Android Studio and targets in XCode. The idea is to create different packages with same core functionality but with minor difference in features. This can include different color schemes, branding or some functionalities unique to a package. A common example is creating a free and paid version of a same application, wherein the paid version has same core functionality as the free version with some added functionalities and features. Since the major functionality is the same there is no need to create different projects, but handle flavor/target specific changes at run-time. I hope you get the idea.
