Swift app development has long been associated with client-side applications, but what if we told you that this powerful language can also be used for server-side work? In a recent case study, Cultured Code demonstrated a four times performance gain at one-third the cost compared to their legacy Python 2 system. But before you start building your own Swift-powered servers, beware of slow builds and immature libraries.
The Power of Consistency
Swift is primarily known for its use in application development on Apple computers and devices. However, its versatility extends beyond client-side work. In fact, Swift's consistency across platforms makes it an attractive option for server-side development as well. By using the same language on both client and server, developers can simplify programming and reduce complexity.
A Case Study of Swift App Development
Cultured Code, the developer of a popular personal task manager for Apple platforms, recently replaced their Python 2 application running on Google App Engine with Swift running on Kubernetes, hosted by AWS. According to Vojtěch Rylko, responsible for development and operations, and Werner Jainek, CEO, the move improved average response time by four times while reducing average compute cost by three times.
The Benefits of Swift App Development
The new Linux application uses Vapor for building HTTP servers and APIs, which leverages Apple's SwiftNIO for asynchronous event-driven network programming. With around 30,000 lines of code, the application builds in just 10 minutes using Xcode for coding and debugging. The database is AWS Aurora MySQL, while Redis is used for ephemeral data. The application is deployed to a small four-node Kubernetes cluster.
Challenges and Considerations
While Swift app development offers many benefits, it's not without its challenges. One major issue is the lengthy build time, which can cause frustration for developers testing code changes. Additionally, Swift's server support may not be as mature as other languages. However, recent work on Swift-Java interoperability may make gradual adoption easier.
The Future of Swift App Development
The team at Cultured Code is encouraging others to explore the possibilities of server-side Swift development. With its potential for simplifying programming and reducing complexity, this technology has the potential to revolutionize the way we approach app development. So, what are you waiting for?
