How To Develop An Application On IOS?

The iOS market is less important than that of the Android application. But that’s not a reason to ignore it, quite the contrary. This OS occupies an important part in certain developed countries. The owners of iPhone and iPad are a high social category target. In addition, since early 2019, the iOS Store has generated 1.8 times more revenue than Android.

Creating an iOS mobile application therefore remains relevant under a few conditions. But how do you develop an iOS application ? Depending on the method used to produce it, the costs will be different. Some tools allow you to create an iOS application easily .

What are the main languages for developing a mobile application ?

To create an app that allows targeting the iOS market, you have two solutions. Produce a native application or turn to a web application. What are the differences between these two types of mobile applications ? Let’s take stock.

The native iOS application

What determines that an Android or iOS application is native ? It is native when its coding language is the same as that of the OS. The two main types are the iOS and Android applications. Android and iOS apps are the most numerous on the market. They offer rendering and functionality that is currently unequalled.

IOS or Android apps are exclusively distributed on Apple and Google Stores. These brands have made native development easier. For the iOS operating system, the most used development environment is Xcode. This tool offers a Graphic User Interface (GUI). It contributes to the simplification of the development of mobile applications. He also embarks on a SDK (Software Development Kit) dedicated to iOS. What are the programming languages to be mastered to produce native applications ? Knowing how to use a development environment is essential. But you also have to be able to write code. Objective-C is the historical programming language, it is an extension of C. Its weak point is its complexity.

Swift, created in 2014 and worn by Apple, is intended to simplify coding. It’s Objective-C without C, its syntax is clearer, it’s easier to learn. Many online resources (moo, tutorials and certifications) exist. They allow you to improve your skills in mastering programming languages.

The Web application

The web application works on all operating systems. Currently, the Progressive Web Application (PWA) is the best. It’s a very successful web app. It has a number of qualities previously held by iOS and Android apps.

What are its advantages ?

PWA is produced with a specific framework that adapts to Android and iOS operating systems.
It is performed by browsers and Telephone Services Workers.
It is available via a URL, without going through the Stores.
Once installed, it displays your logo on the iPhone and iPad home screen.

It operates offline and accesses certain internal functions of iOS or Android smartphones.
It is coded in HTML5, CSS3 or JavaScript. A web developer does not need to learn new language. It is a considerable time saving. An option to consider if you want to create a mobile app.

How to develop well for iOS applications

The App Store has toughened its filters for publication. The design of an application for iOS meeting Apple criteria is possible. The brand’s guidelines must be taken into account. The developer must start from the specifications provided to him. This describes the environment and the functionality of the iPhone and iPad app to develop. It will also include models. A major application design phase for iPhone will follow. This consists of :

• The choice of patterns (or design pattern). They provide a framework for the development of mobile applications. They describe a recurring arrangement of roles and actions played by software modules.
• Tools usable within the programming language (the necessary external APIs).
• Bookstores for native applications. The external libraries necessary for the operation of the iPhone application must be listed.
• The evaluation of each user-stories allowing the development to be carried out.

The mobile application development phase comes after. That of iOS is based on Xcode, it includes :

• The Storyboard tool (design of views of mobile applications)
• The simulator and the debugger (test of developments as they go along).
• Static analysis (verification of code quality).
• Memory measuring instruments. You have to be very vigilant about the CPU and the ARC.
• The version manager (GIT can be used).

The test phase after designing an application immediately follows. It is crucial, especially at Apple. This amounts to :

• Perform unit tests or “trades.
• Analyse the code to remove obvious errors.
• Check the use and solicitation of memory.
• Observe the consumption of the battery: watch out for dust uses such as GPS, camera.
• Perform functional tests. We must ensure that the specifications are respected.

Develop its application for Android

If you want to develop an application yourself, it is possible. For Android, developing applications for mobiles is simpler. The Kotlin and Java programming language are the languages used to code an Android app. Android Studio is the development environment (or FDI – Integrated Development Environment) that will have to be controlled.
Don’t you want to waste time in learning ?
The App Builder allows you to create yourself without learning development. The digital agency is the ultimate solution.

Simply create an application for Android

Android and iOS are the two major families of native applications. Android occupies 80% of the world smartphone market. It has generated twice as many application downloads as iOS. It is present on most major smartphone brands and has its programming language.
Creating an Android application without a code is possible with the App Builder. Against a subscription, you create your app yourself without coding. Prices are accessible. They include technical support, maintenance, publication. You create native apps, and web apps (PWAs).

Integrate a database into its app iOS and Android

How to create a database for mobile application? Internal solutions exist with an App Builder. Specific plug-ins are offered. They allow you to connect your app to a database. Results will be returned based on a request typed in the app. External solutions are also available. MySQL is an SGBDR (Relational Database Management System) which can connect with an Android and iOS app. According to the OS, the solution can be complex to develop.
