There are several benefits of using Swift on the server side. Some of them include:
- Being able to work on a feature as a whole: Being able to work on an entire feature helps deliver the feature on time and as expected. Traditionally, teams are divided into frontend and backend teams but if you have the same language used for both front and backend then it will help developers contribute to the entire stack. Developers working on building the app can create the API endpoints needed to avoid the unnecessary back and forth between developers and prevent an app developer from being blocked by the backend engineer and move the feature development forward.
- Working with familiar language and tools: Working with a familiar language reduces the biggest hurdle to working across different stacks. You can build both mobile and server-side components using the same language and tools. Swift developers can use their favorite IDE, Xcode, to build their backend server and do not have to learn new tools or install different IDEs.
- Sharing code base: Code shareability is another big win for using Swift as you can share models, validations, and business logic easily across platforms. Not having to rewrite the same logic in different languages saves times and helps avoid expensive bugs caused by inconsistencies introduced by different developers who might have worked on rewriting the business logic on a different stack.
- Leveraging great APIs: Apple did a great job building easy-to-use APIs on their platform and now being able to use those APIs server-side is a big benefit for developers as they do not have to learn new standard libraries or reinvent them on the Linux platform.
