With the growing demand for Apple users, the demand for iPhone Programmer is also increasing with each passing day. Any company that wants to reach a large chunk of the market using Apple products need to avail the services of an iOS Development company. There are one billion users of the Apple products in today’s world according to the latest statistics released by Apple.
Apple watches, iPads, iPhones, Mac are in application in day to day life. But iPhones and iPads have been the important products and have observed a tremendous growth in the last ten to twenty years. An iOS Development Company works on the programming of iPhone and iPad. With all such kind of functionalities, becoming an iPhone Programmer is not going to go out of style.
For becoming an iPhone Programmer in any iOS Development Company, a developer needs to possess certain skills as follows:
Swift is a Programing language created by Apple specially for developing its apps. For any future development of iOS, this programming language will be necessary. Therefore, having knowledge of it is very important. The language is not a small and easy language but the programmer should know the basic syntax, the Control Flow, the standard library, etc. The Compiler is necessary for performance. Whereas, the language is necessary for the development with best results in each of them. Swift allows one with the experimenting of the codes and gets immediate results. It also helps in expressing the most complex ideas and functions in a very clear and precise manner thus making it easier for understanding.
Xcode is the development environment within which the iPhone apps are created. It is for the installation only on Mac and not on Linux or Windows. When one wants to develop apps for Apple, it is necessary having a Xcode on the Mac. It provides a platform for developing the apps for Apple.
The Interface Builder Built-in allows designing a user interface. All one has to do is to simply drag and drop windows, text fields, and other objects onto the canvas for creating a user interface. Hence, one can develop an effective user interface without writing.
It is a User Interface framework for developing software programs to run on iOS for iPhone, iPad, iPod, etc. Cocoa Touch is usually written in an Objective-C language. It offers the features such as app extension, multi-tasking, auto layout and much more. Cocoa touch also provides such features which are not available on Mac. Thus, it becomes unique for devices with iOS Operating Systems.
The ability to think about the objects in three dimensions and then drawing conclusions from it can be very useful for the iPhone Programmer. Looking at the app with different dimensions or visualizing it in a different method when rotated can be helpful in knowing how the users will perceive and interact with the product. Learning this ability can be useful for developing apps and for building relations between the objects.
There are specific guidelines one needs following for an effective outcome of the apps. There are guidelines for How the app should look alike? How should the components be there on the screen? How to store the data? and a lot more. One also needs understanding the way in which the app should interact with the user. In iOS, MVC (Model View Controller) is applicable for representing a structure of an application, for presenting data to the user in a defined manner, for the storage of data, updating as per the user interactions. It is also easy to use with the programming languages such as Java, C++ and others. Notifications are also necessary as a medium for passing on the information from the sender to multiple receivers. There are other guidelines as well which are easily usable in app development.
Core Data is the persistent framework provided by Apple for storing data on Apple devices.The persistence feature helps in storing data and retrieving it as well.It stores the data of the users so that the users don’t have to re-enter the data again and again when they open the application.In comparison to other ways of storing data, Core Data works out to be the best in storing complicated data. It is not a database but, it is more object oriented for mapping the objects easily in the applications.
Grand Central Dispatch is a thread tool pattern especially for distributing computations across multiple cores. It can distribute any number of threads as per the need and can work efficiently with multi-core processor devices. GCD works with blocks of code which are necessary for carrying out an execution in a specific order or queue in the background. While using GCD it becomes easy to focus on other tasks as it takes care of the multiple threads.
To be a good iPhone Programmer knowing programming languages such as Xcode, C+, C++, JSON etc. can be an additional advantage as well. But, these are the core things that an iPhone Developer must possess to be successful as an iPhone Programmer in an iOS Development Company.
