The iPhone has been a game-changer in the world of smartphones. It has set a benchmark that others in the industry look up to when developing their technology ecosystem and the hardware. Because of its stringent quality check and high user expectations, even the apps that are put up on the Apple App Store are nothing short of innovation at work. Only the best iPhone app developers can profess total competencies in programming languages such as Swift and Objective-C. Using these programming languages, Apple ensures that its loyal fan following gets the best possible user experience.

How Did Swift And Swift 3 Come About?

The earlier app development scenario relied heavily on Objective-C. However, with fierce competition and technological advancement, the increasing user demands meant that Objective-C started to fall short of delivering on these expectations. The iPhone app development community felt the strong need to come up with a disruptive solution that would ease their programming efforts and be able to incorporate all the modern day features that the new age iPhone users would demand from Apple.

This is where Swift was born – to bridge the gap between mounting demands for a better user experience delivery and the shortage of means to meet this demand from the existing bunch of programming languages available. While initially, the learning curve was steep, Swift was able to deliver immense value once it was mastered by top app developers.

Swift 3 is a result of the continuous efforts put in by Apple team of engineers, who want to make the lives of developers easier, simpler, and more productive. All the problems that made Swift counter-productive are more or less taken care of with Swift 3 – the version that was formally launched on 3rd December 2015. The need for this change was simple. Apple wanted to maintain its smartphone dominance when it launched the iOS 9 and 10. For this, it was necessary to come up with an improved version of Swift. And this is what Swift 3 promises to deliver – better portability, streamlining code results, and a brand new code library

What Is New In Swift 3?

The short answer – pretty much everything!

In fact, developers looking to migrate their old code (from Swift 1 or Swift 2) will find it practically impossible to run their code on Swift 3 unless you make the desired changes. It is critical to first familiarize yourself with XCode 8 that has the necessary coding to let you migrate from the older versions to Swift 3 without much hassle. With Swift 3 the top app developers can develop high-performance apps that are relevant for today and ready for tomorrow. The Swift 3 programming language has the necessary fuel to fire up your app development process in the right direction. Let’s explore how Swift 3 enables this tremendous advantage to the best iPhone app developers:

1.Feature packed: The world is constantly demanding something fresh and new from their mobile apps after a period of time. The functionalities built into the Swift 3 language provides top app developers with ample avenues to hone their innovative skills and develop apps that look fresh and provide an elevated user experience.

2.Syntax improvement: With a range of enhancements made to the coding syntax, Swift 3 will definitely ease out development pains. In addition to eliminating unsafe codes, memory management becomes smarter and more evolved than before.

3.Saves coding time: Writing complex programming codes is now a thing of past. Swift 3 provides easy coding experience and drastically reduces the time taken for coding. The developer can instead use the time to build in innovative functionalities within the app.

4.Better feature list: Swift 3 has a lot of distinct features like the omission of unnecessary words in method names or the need for function parameters to have labels. Adding these functionalities on top of the previous versions means that Swift 3 is bigger and better than before.

Best Practices To Ensure Smooth Migration To Swift 3

Only two steps are needed to ensure successful migration of code to Swift 3. One is the pre-migration validation that happens prior to the actual migration taking place. Make sure that your code is passing each and every pointer in the pre-migration preparation phase. You can also utilize a migratory assistant to help with the necessary modifications to be made.

The second step is to do a migration pass. This facility is available with XCode 8 and lets you initiate the migration process from the previous versions (i.e. Swift 2.3), by calling the migration assistant.

The best iPhone app developers never shy away from learning as a part of their responsibilities. Hence it is these top app developers that will be a good choice to help businesses reap the benefits offered by Swift 3.
