The mobile app development industry is a highly versatile and competitive field to explore. But if you think you have got the potential to stand tall in this domain then you can be highly profitable. You can be extremely lucrative by staying in this industry for good. After all, this industry has been evolving tremendously. The popularity of mobile apps among the users and the incorporation of advanced technology are just a few of the perks of getting into this side of the industry. Yes, there's no doubt that it has a bunch of complexities of its own but which industry does not. The Android and iOS app development in India, Japan, USA or anywhere in the world has seen major success over the years. But before diving into the world of iOS app development there are a few things to keep in mind. Here we present you a list of 8 fundamental principles for you to remember before you start developing iOS apps.

1. Developers ought to be critical

If you are just starting off in this field as a beginner then let us tell you this, that, the majority of work will be with the developers. The first phase in the app development will involve plenty of critical reviews from experienced iOS developers. All your concept, storyboard, app framework, coding, etc will go through your senior developers. Make sure to take notes of all the advice or guidelines delivered by the seniors as these will be of extreme help for you in the future. If you wish to thrive in this domain then you got to be prepared for facing the criticisms. There’s no escaping from this. You’ll learn and eventually grow to become better in iOS app development.

2. App development begins with a user interface (UI)

The real app development begins with the designing of the user interface (UI). You are required to create an intuitive UI for achieving success in this field. This part of the app development usually starts after you are done creating a wireframe for your app. The UI along with the UX (user experience) design lays out every user screen that will interact with the storyboards. This is also termed as views. Basically, the User Interface is developed along with the storyboards and interface builder. You have to understand this section of the development creates a base for the functionality of your app - the interactions among the database, UI and the user who make the app function.

3. Model-view-controller design is the core of iOS development

One of an integral parts of iOS app development is the model-view-controller (MVC) model. It is a code-breaking pattern that fragments the code in three essential operations. The three functions involved are -
  • User interfaces (views)
  • Data (model)
  • The software that interacts between the two (controller)
The MVC design is the top-quality procedure of developing a solid iOS app. Even though it is a high functioning framework for a successful iOS app design it is a complex procedure for adoption. However, you have to keep this in mind that you got to incorporate this framework in your app development. Since it is considered to be the core of iOS app development.

4. Every iOS app is backed by event-driven programming

Now, when we talk about the interaction between the UI and the data, you have to note that it is always caused by an event. By event, we technically mean that a user action that ultimately sends a request and manipulates with the app's data. Lastly, sending the response back. Therefore, laying down a clear definition of these interactions is vital for your app to function properly. Plus, this even builds groundwork for every code that eventually executes the app's logic. You have to understand that every app is powered by an event-driven program.

5. Building blocks with design patterns

One of the aspects of software design that resolve a specific recurring problem is known as a design pattern. Plus, in iOS app development, you get the option to choose numerous such patterns. You have to remember that the design patterns offer solutions for the daily issues related to coding. They gradually offer the developers the efficiency to write code which is more solid, extendable and simple to edit. Design patterns can essentially be creational, structural or behavioral. You need to keep a note that these patterns act as a frame for the written code in the following phase of your app development.

6. Front-end and back-end of app development

Both the front and back-end of app development has to be built in a series of synchronized activities. This phase of app development is essentially termed as software architecture planning. This part of the phase is worked upon simultaneously with the UI design framework. Plus, it even involves several iterations of edits on feedback. The developer has to ensure that whichever design is projected must also be supported on the back end. In a front-end app development, the following are included -
  • Synchronize database
  • Caching of database
  • Development of protocol designs and wireframes
  • Testing
  • UI design & development
  • Deployment
Whereas the back-end development includes the following -
  • Set up of back-end structure
  • Managing the user authentications and accounts
  • Maintaining the server-side functions
  • Customizing UX design
  • Integration of data with the third parties via social websites
  • Push notification service

7. Testing repeatedly

Since Apple is highly concerned about following the guidelines set up by the company, the testing phase of the app has a crucial role to play in iOS app development. If the app fails to abide by the guidelines set by the Company then all your effort would be for nothing. The reason why we tell you this is because not following them ultimately means your app will be rejected to feature in the App Store. It is an extremely essential pre-launch step that is mandatory to go through. Testing the app's functionality and user feedback will shape up the submission process. Make sure to run the test a number of times so that no stone remains unturned. In a typical testing phase the following steps are involved -
  • Preparation of test case
  • Automatic script detection and modification
  • Manual as well as automatic testing
  • Performance testing
  • Usability testing
  • Device testing
  • Compliance and security testing

8. Submission to the App Store

As we are closing towards the final steps in the iOS app development, the submission phase of the app is not as easy as it sounds. You may have been done with all the heavy work involved in the development process but one significant step still remains to be initiated. This is the submission of the app developed into the Apple's App Store. It involves the below-enumerated steps for getting your app live in the Store :
  • Creating the app id or identifier
  • Creating an iOS provisionary profile for app distribution
  • Configuring your target audience’s build settings using Xcode
  • Creating a listing for App Store
  • Creating a build for release
  • Filling the app version information
  • Submission of the app version for review
  • App launch

9. Maintaining the app with consistent updates

The above listed principles holds a significant position for iOS app development. However, a developers job is not over since he or she has finished launching the app. In fact it is just the beginning. If you aim for your app to remain on the track of success then you got keep an eye for maintaining regular updates of the app. You got to make sure that the app runs smoothly on the current iOS updates and developments. A developer’s expertise is needed even if the app has been coded and released in the App store. So now that you know these essential principles of iOS app development there is no question for you to not start off in this field with a kick. An iOS developer’s job does not end with the release of app into the App Store. In fact, the real responsibility begins from there. The companies in this field have evolved over the period and with these iOS app development has grown incredibly. Whether it is iOS app development in India or in any other place of the world, these principles are applicable for all. You will achieve the heights of success if you follow the above-mentioned fundamentals diligently. So don’t wait up! Don’t forget to incorporate these principles and you’ll be amazed to see how rapidly you prosper in this highly competitive and versatile industry.
