Considering Apple's favourite language for app development, Swift, it has managed to gather far-reaching effects on all platforms, not just iOS, OS X, watchOS, and tvOS. Swift definitely sidelined Objective-C. While Apple has not announced any plans to shut-down the Objective-C language, since we can see that they are still updating Objective-C, Swift has rapidly taken over Objective-C and has become more popular on Apple's platforms.
iPhone app development or rather Swift app development services to be precise has come out as one of the most lucrative business ventures. Companies and service providers all over across the globe are hopping on to the platform. And this stems from Apple’s constant zeal to provide secured and some of the best native apps.
There are strict guidelines and stringent protocols put forth by Apple when compared to the industry standards and any company or developer must adhere to them at any cost.
Swift brings a lot of modern programming niceties to Apple's platforms. With the current upgrade, the ABI now remains stable on Apple platforms. This ensures, Swift libraries now will get incorporated into every future release of macOS, iOS, WatchOS, and TVOS. Developers involved with Swift app development services will no longer have to include these libraries. Hence, iOS applications will now be smaller and easier to build.
Here is everything new and updated in the latest version of Swift
- The new dynamically callable types have been enabled to improve the interoperability with other languages like JavaScript, Python, and Ruby.
- The latest version of the language Swift 5, defaults to enforcing exclusive access to memory for release and debug builds. This has been done so in order to enhance Swift’s overall safety.
- Swift 5 now has a reimplementation of String, new data types, and enforcement of exclusive access to memory during runtime.
- The latest Swift now leverages string literals delimiters for it to support the raw text. Single-line and multiline string literals have been enabled and can contain any content.
- When you will look at the standard library, you will find that String has been reimplemented with UTF-8 encoding instead of UTF-16. This now results in faster code. Objective-C interoperability is preserved.
- The library for single instruction, multiple data or SIMD vectors gets exposed as a subset of operations on the SIMD types supported by most processors in the library.
- The Unicode properties that support common and advanced text processing have now been added to the Unicode.Scalar type.
- Result type has been added in order to improve error-handling.
- You will find that Swift Package Manager has target-specific build settings, dependency mirroring, customized deployment targets, and an ability to generate code coverage data.
- The swift run command now has the ability to import libraries in a read-event-print loop (REPL) sans the need to construct an executable.
- Performance improvements have been made to Dictionary and Set.
Conclusion
iOS app development has a strong future and immense potential when it comes to the range of actions and abilities one can lend to the app on this platform and it becomes quite evident even with a cursory glance at the Apple App Store. When you compare on the number game, Android apps lead, but when it comes to the revenue earned, the iOS platform is the winner.
