Swift 5.7 come with major additions to its standard library and compiler to offer an enhanced iOS app development experience. So, what are the new features in Swift 5.7 which make it more intuitive and useful for iOS application development? Let us explore the top latest features of Swift 5.7 programming language.

Overview of Swift 5.7

Swift 5.7 is the latest updated version of Swift 5 programming language. Swift 5.7 is part of the Swift 5 family which consists of similar functionalities but with some added new features. Swift is Apple’s native programming language for building iOS apps for macOS, iPhones, watchOS, iPadOS, and tvOS. It allows developers to write simple and concise code. Therefore, Swift is widely preferred by the iOS developer community. Businesses mostly look to hire iOS app developers with Swift programming capability.

Top new features in Swift 5.7 for iOS app development

The latest Swift 5.7 comes with many enhancements and new features. It is the culmination of numerous contributions from the Swift developer community. However, the new Swift 5.7 offers various improvements. Here we will take a look at some of the prominent features.

New Generics Implementation

The type checker’s generics implementation is now updated in the new version of Swift 5 language. With this updated feature, developers don’t find difficulty in handling the complex same-type requirements in programming. It is because the latest update fixes various long-standing bugs related to managing same-type requirements. As a result, it improves accuracy and ultimately performance.

Code completion

Code completion has also got substantial improvements. The latest update enables the code completion to offer more accurate results inside ambiguous code. It is much more accurate and faster than its previous version. Therefore, it improves iOS developers’ accuracy in iOS app development.

Improved SourceKit-LSP

SourceKit-LSP has got many improvements. The new updated SourceKit-LSP support Sowft’s Visual Studio Code extension. This updated feature enables compiler arguments to be recomputed after changes to the Package.swift, compile_commands.json, or compile_flags.txt. So, as a result, it makes sure that semantic functionality like code completion continues to work seamlessly after these changes. If there are several SwiftPM projects are open in the same Visual Studio Code workspace. Then, the new SourceKit-LSP can handle them in a single server instance.

Improvements In Automatic Reference Counting

In the new Swift 5.7 language, ARC (Automatic Reference Counting is now more user-friendly, performant, and predictable. It specifically new rules to reduce the lifetime of variables when optimization is enabled. The updated ARC protects iOS app development from complex-type bugs which only appear at runtime in optimized builds. This also supports the introduction of heavy-size optimization without disturbing the existing source.

Wrapping Up

The latest Swift 5 version offer various updated and improved features for building iOS apps with better accuracy and efficiency. Swift 5.7 primarily focuses on improving the overall developer experience and enhancing the quality and speed of iOS app development services. However, since these features are relatively new in the market.

Hence, only experienced developers as of now can help you take better advantage. Therefore, if you want to utilize the latest Swift 5 programming language in your iOS app project, then you should try to hire iOS app developers who have solid experience with the previous Sowft version and the latest tools.
