There are no doubts about the fact that iOS app development is getting popular as  compared to other app development platforms like Android, Blackberry etc. We completely owe all the popularity of iOS smartphones or iPhone to the amazing features that an app in an iPhone can have.

Right from the 3D game apps to robust AR/ VR apps, the immersive user-experience is giving chills down the spine. With new features introduced in every other launch of the iPhones there is no doubt about the fact that the iOS developers need to keep up with the trends that are most liked by the users of iOS app development.

A professional iOS developer is always in need of the rules and principles that lead to better iOS application development. Even, every iOS development company should follow the following 8 principles that will vene ease out the mind-boggling process of developing variety of iPhone apps for their clients.

How important is it to be aware of the principles of iOS app development?

Without knowing the basics of developing apps for iPhone, it is not possible to make continuous improvement. The base should be such that there is no use of going over the issues over and over again.  
 
So, a professional iOS development company should make sure that the developers who create the apps in the company are certified and experienced enough that they are aware of the principles that we are going to discuss below:

1. Analysis or Pre-research with professionals:

A professional in developing the apps for the clients knows it well that he has to work with the iOS app designer to build several components of an iPhone app.  
There are many processes that take place with the combo of the designer as well as the developer- wireframing, storyboarding and presentation of the ideas. The UI Model, coding as well as programming for the app. A certified professional in developing iOS apps is the only person that can help you achieve the business goals with an app.

2. Follow MVC guidelines to the core: 

There is a vital programming model that helps the apps to work as expected or when an action is assigned.  
 
Functioning of an iOS app:
 
1.UI or UX of an app (a user views)
2.Information (demonstrates)
3.The channel that conveys between the two. (controller).  
 
An MVC framework lets the developers in iOS application development create actual functioning of the app and how the app will work in response to the action of the user on the app.

3. Stunning UI is the fundamental block of an iOS app: 

When you are developing an app working in an iOS development company, you have to make a wireframe first, which contains the ideas, the UI/ UX of the app, all the screens of an app and most importantly, all the codes. It is to be noted that a wireframe is laid out according to the storyboards. UI- Storyboards and the Interface Builder makes the UX of the app.

4. Occasion-driven programming is the key: 

In iOS app building, it is the collaboration or communication between the various elements discussed above that take place when you activate the action. When an app user clicks on the option on the app, an occasion-driven programming takes place. An occasion is activated by a user activity, which sends a command, it controls the app’s information, and at that point sends the response back. This functioning of the app should be well-known by the iOS developer.

5. Back-end development aka. Coding part:  

When the UI part or the graphic designing of the app has already been designed with the collaboration of a designer and developer as well as the clients, now is the time to make coding part a reality. The coding helps in making the designs come to life with Xcode as the environment for Integrated development in Swift coding language for iOS.

6.Various revisions and simulator testing: 

Reconciliation testing, unit testing as well as other debugging and troubleshooting issues come to this part of iOS application development. There should be and is, always a room for improvement when it comes to building any app.

Conclusion: 

If any iOS development company follows the principles above, there will be marked difference in the development processes for sure.
