How time is consumed through the process of IOS app development?

Smartphones and mobile application development have revolutionized the manner we tend to consume info from the internet. Today, applications are evolving to become a lot of and more a utility that permits you to try to to something from managing your finances to booking your travel tickets and ordering food on-line. they're simple to use, quick and permit their users (and developers) to exploit the full potential of a smartphone.

To get a good plan of the huge quality apps are enjoying at this time, contemplate this: the world's most well-liked digital distribution platform, the Apple App Store has over 1.5 million unique apps, with one total transfer of a hundred billion apps to date! By the time you scan this sentence, concerning 1000 apps have already been downloaded and installed on the same number of iPhones. and also the numbers are rising exponentially.

 It's a huge market! And an extremely lucrative, at that.

But even with all its ease of access and ease of use, designing, developing and publishing an application is a terribly difficult process. From the development to the putting on line of your application on the App Store, the road that must go through an application is long and is by no means a bed of roses.

Wireframing and Concept Design

The process begins with the design concept. You have a great idea that you think works very well as an application; so you hire a team of developers and designers to make things happen for you. Once you've put all your ideas and projects on the table, it's time for the app development team to take over.

What is Wireframing? How Does it Work in iOS App Development?

A wireframe is an image or set of images that displays the functional elements of an application with all its screens, used to plan the structure and functionality of an application.

Once you have decided on all the possible screens to develop for your application, your mobile app developer freezes them and switches to wireframing. Keep in mind that once screens are frozen, they are not likely to change; you simply cannot add or subtract, without having to start the whole process again.

With wireframing, it's also where you discuss workflow with your developer. Workflow is the complete functionality of your application, and how different screens interact with each other, divided into a set of fixed steps. Any particular feature you would like your application to SHOULD be mentioned here.

Development

Native iOS apps are developed using the iOS SDK. Just like the Mac, iOS SDK is based on Xcode IDE and is programmed using Apple's proprietary coding language called Swift.

Why is Mac OS important for Developing Apps for iOS When Swift is Open Source Language?

Swift, being open source, is a program that can be run on any operating system. However, the available IDE, which is Xcode, is only supported on Mac OS. Swift can be used successfully to write basic applications that can be developed and tested on any operating system; but for the full development of the application, Mac OS is absolutely necessary.

That and iTunes Connect (Apple's platform for creating applications) works only with Xcode.

What all Factors can Affect the Development Process?

A number of factors come into play and can dramatically influence the time and effort required to develop a complete application.

-       Animations and Intensive Graphics: An application that relies heavily on visual elements is more complex to code than an application that only needs to display data in text or rich media format.

-       Communication between different screens: All screens you choose to have in your application must be perfectly synchronized with each other to ensure smooth transitions and consistent functionality. The higher the number of complex screens, the more information they share between them.

-       Resources and different iOS SDK APIs that must be integrated into the application. for example. Push notification API, photo API, master data, etc. (material) (gallery)

-       Memory and Performance Optimization: Have you ever noticed how an iPhone beats most other phones in terms of performance and RAM utilization, even with half of the technical specifications? This is mainly because each app on the App Store is optimized in terms of performance and use a minimum of memory during its operation. This is not optional, Apple has been known to refrain from publishing applications that consume too much memory or delay in terms of performance.

-   Management of the various state transitions of the application, for example when the application is active or running in the background or when it is in Standby mode.

-       Number of devices with which the application must be compatible.

-       Modes in the application (Landscape / portrait / both).

-       Make the app compatible with the Apple guideline.

-       Cache that the application keeps.

 All in all, how long does the development process take?

Again, it depends on the complexity and scope of the application, but the development time can be broken down into the time needed to develop individual screens (logical to display).

What is the Time Taken to Develop a Single Screen?

It depends on various factors. Things like the number of components, component types such as tabs, image views, map views, and the integration complexity of all of these components need to be taken into account. On average, it can take up to 3 to 4 days to develop a single screen for a moderately complex application.

Creatives must be created separately and integrated into the app.

Testing and Publishing

Having an iOS app developed and ready at your fingertips is a half done job. The real task is to publish it on the App Store. Apple is infamous for its strict application review guidelines and high rate of application rejection. The reasons are essentially the same: the application is buggy or does not do what it is supposed to do.

Before an application is submitted to Apple for review, it must be rigorously tested on all target devices. At SPA, we are testing an application for the 5 most recent iOS mobile devices: iPhone X, iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus and iPhone SE.

Does it also mean that the app is compatible with iPads?

Nope. For iPad compatibility, you always need additional coding to account for changing screen sizes and other variations.

How fast can an application be published after its development?

It takes about 10-15 days (minimum) to get your app published on the store.

Are unit tests a necessity?

Test-driven development is the recommended approach, but you should be aware that this can significantly increase the development effort. In addition, for test-driven development, the application must be architected in a specific format.

Unit tests are such that for each line of code written in the application, you add in another line that tests the code when it runs. It's almost double the development effort.

Beta testing is also important and can be done via Testflight.

What does the review process look like for publishing an app on the App Store?

Once your app is sent to Apple, it will be reviewed based on content, performance, design, and technical details. You should refer “Apple Revision Guidelines” page for a detailed overview of the different standards to follow for your app to be accepted by Apple. Apple also has a list of common reasons why apps are rejected here.

You must provide the following information for a successful review by Apple:

●     Website URL

●     URL of the privacy policy

●     Legal name of the company

●     Description of the App Store

●     Screenshot

What is the typical period of the review process?

It takes a minimum of 2 weeks of work to get an answer from Apple.

Well, if you are looking to build an app for your business, be prepared for the long run. Understand the process.
