Apple Professional Development: What should you know to build your own iOS app
- Charging users for the downloading the app,
- Implementation of a paid content and features for the premium access,
- Integrating in-app advertising.
Where to start with app development for Apple devices?
Target audience identification
Market researchHave a look at the market dynamics of the mobile app industry and distinguish recent tendencies and trends in mobile app development. Make sure that the program idea has something unique, something that will make users prefer your application to the others in the market.
Competitors analysisCompetitive landscape investigation can help to determine the most suitable strategy. Have a look at the key players in the app category you are interested in. Learn from the competitors’ mistakes and use their experience to succeed.
Target audience identificationFind out the user's needs. Keep to the user-centered approach and make people got interested in your offer by providing them what they need. For instance, you can find applications in the Apple App Store which will resemble yours and read users reviews. Among these reviews, you will find a lot of useful data on what existing apps lack and cover these weaknesses in your program.
Specification listWhat type of application would you like to develop? Determine whether it is going to belong to a social networking, finance, entertainment, navigation or any other category and identify its features set. It is better to start the development with a clear idea in the mind then to grope the way. First of all, such approach provides better control over the expenses and timelines. Secondly, it will help to determine the development cost if you approach the professional software developers.
What tools use professional developers?
Apple Developer Program
XcodeXcode is an Apple IDE with a suite of software development tools for creating software for Apple products including iPhone, iPad, Mac, Apple Watch and TV. An integrated development environment is a program that lets developers build software solutions with the help of source code editor, additional tools that automate some building processes and debugger. In the case of Xcode, IDE also contains the Interface Builder which lets developers create app interface by means of graphical user interface and without writing code. The latest version of Xcode was significantly accelerated with new editor extensions and runtime issues which alert about hidden bugs and let debug them in a static code. Whether you are a professional developer or not, you can’t build a native iOS software without this IDE.
Programming languagesInitially, to write applications for iOS platform developer should have known Objective-C as the only programming language for iOS software development. It is still considered to be the primary language when you deal with OS X and iOS as it provides a dynamic runtime and object-oriented capabilities. But in 2014, Apple released their own programming language called Swift. The purpose of this release was to simplify a code writing process making it feel natural. Swift is a combination of modern features and safe programming patterns backed by Cocoa and Cocoa Touch frameworks. The latest updates made it even more harmonized with system APIs such as Grand Central Dispatch and Core Graphics.
Apple’s APIsAPIs are application program interfaces which present a set of protocols, routines, and other tools that help developers build software solutions. APIs not only specify the interaction between software components but also used for programming GUI (graphical user interface) components. APIs also allow developers to integrate third-party software using existing functionality. In other words, APIs provide building blocks, and professional developers put them together creating an application. For example, you can use Google Maps API to integrate Google Maps functionality in the software product. In the Apple’s API References you can find full information about frameworks available for building iOS and OS X. There are mentioned six sectors which include: App frameworks, Graphics and Games, App Services, Media and Web, Developer Tools, and System.

Even if you decide to use only Swift, this course will be useful for the beginner who wants to become a professional one day. Read more about learning to code iOS applications in this article.
Should I use DIY platforms to build iOS app?
- The features set is extremely limited;
- The customization level is low, providing template designs;
- The performance is questionable. Even professional developer building software for several platforms faces problems caused by operating systems incompatibility which leads to bugs in performance. DIY app builders do not pay as much attention to the quality of the performance and, in the end, deliver an application that doesn’t even work on some devices.
