Why Swift

Swift is a powerful programming language that brings about numerous benefits.

A safety mechanism

The Swift language has an inbuilt error-handling mechanism that helps to early detect bugs and prevent crashes in production. The ability to identify errors while writing code also saves time and money on future maintenance and bug fixing.

Unparalleled performance

Under the hood, Swift has an optimized compiler that promotes faster code generation both for release and bug builds. Swift was designed with a view to outperform other mobile programming languages and is famous for the speed at which it runs app logic.

Reusable code

Hire Swift developers at Altoros to build a single codebase responsible for executing the same business logic across the entire Apple ecosystem, as well as Windows, Linux, etc.

Faster updates

Achieve ease of maintenance by synchronizing and deploying updates across multiple platforms, minimizing manual effort.

Low memory footprint

To minimize memory usage, Swift utilized dynamic libraries instead of static ones. The latter are locked into the code, increasing the size of executable files and prolonging loading times. In contrast, the dynamic Swift libraries are loaded on demand. Swift also relies on its native ARC technology to track and automatically manage memory resources.

Ease of maintenance

Swift’s concise, easy-to-read syntax coupled with automation of routine tasks helps developers to focus on improving the app and delivering new functionality.
