Front-end and Back-end Programming and Integration: How it Happens on iOS

iOS app programming is a complicated process that consists of two phases: front-end nad back-end. This is the most complex phase of the whole development process - several iterations are required and there is a continuous feedback loop between the designer and the developer. At this stage, the application's front-end and back-end architectures are created as coordination efforts. When you create the functionality of an app, your system architecture is under construction. The front-end interface and the back-end server support software depend on each other, and the process often involves many comings and goings.

Tools: Programming Languages and Frameworks

On the front end, our developers use code-calculation logic to determine how your app's functionality becomes a reality. Some of the techniques you should know when discussing options with mobile application developers include:

  • Xcode. During the development, your iOS programmer will use the Xcode-Apple integrated development environment to build your native iOS application and import any graphics created by the designer. This tool provides several features for creating native iOS applications such as designing user interfaces, editing source code, debugging, and even exporting applications to the App Store. Interface Builder is an alternative to front-end manual coding that allows developers to visually attach code to an application.
  • Objective-C. Cocoa Touch is based on the Objective-C programming language - this is a superset of the C programming language, adding a layer of object-oriented programming. The iOS app is a network of objects, and the object is an Objective C class. The class can be extracted from the Cocoa framework or written from scratch.
  • Swift. Apple's latest programming language, Swift, was released in 2014 and is quickly replacing the previous one. It's easier to learn, and Apple says it's 2.6 times faster. The Objective-C syntax is tedious for programming, but it's great for the first iPhones without the slower hardware and process RAM. The Swift comes with modern hardware and the encoder is faster, shorter, safer and easier to maintain.
iOS App Architecture

iOS apps are created using the Cocoa Touch framework, a version of the Cocoa framework that focuses on a touch-based interface. The Foundation framework provides applications with basic services written in Objective-C. Programming hybrid apps using a Bootstrap front-end framework, jQuery mobile and AngularJS and so on third-party platforms (such as Xamarin, PhoneGap or Appcelerator option), allows the developers to use a language other than Objective-C to write cross-platform applications .

At the same time, any backend works - the server-side components need to run your app, such as database, API and middleware - will be coded and integrated at this stage, and connect them to the front.

Programming Objective

The main objective is to create a full-fledged app that can scale and integrate all back-end software - running databases, mobile APIs, and other related infrastructures. If you do not have a scope to create a server-side infrastructure, you can choose to purchase a Back-end as a Service (BaaS) package. This includes a variety of options and storage features, but they are not completely "turnkey" - you still need to understand the integration of back-end engineering developers in your application. In addition, writing unit tests and running integration tests are important steps at this stage.
