Why choose Swift for iOS app development?

Swift is a safe, fast, and modern language developed by Apple providing impressive features to make the iOS development process easier and better.

Faster and more performant

When it comes to business and markets, time is crucial. A minor change in the performance of your app is able to throw it back from 5 stars on App Store. Apple did its best to make Swift as fast and lightweight as possible.

In fact, Swift is 2.6 times faster than a not-so-modern Objective-C.

Built with security in mind

From a business viewpoint, advanced error handling is one of the best features in the Swift iOS development process. Thanks to the bugs-prediction system, it prevents common crashes in production along with the detection of bugs.

It's a big advantage for businesses as they can save their budget and time on security testing.

Feature-rich apps

Swift is the language of choice if you need to build an app with rich functionality. The programming language allows developers to fully utilize hardware features like gyroscope, camera, geolocation, and others much expected by users from a modern iOS app.

In addition, Swift's codebase is super concise, which makes adding new developers to the team much easier.

Enterprise support

Big-name corporations like Apple and IBM stand behind the Swift Language. The entire iOS ecosystem essentially depends on Swift, motivating Apple to invest the best effort in improving this technology for end-users and businesses. IBM actively explores the possibilities of the Swift iOS development as well.

This makes Swift a risk-free investment in the future of your mobile business.
