Most developers say that it’s fun and rewarding to build iOS apps! But for novice developers it would be ideal to initially follow a roadmap where they can get a perfect starting point to lead the way for iOS app development. As you proceed through this blog, you will obtain the right tools, the best practices, major concepts and approach for developing iOS app.
This roadmap will apparently guide you the pathway to iOS application development using the iOS SDK, Xcode and Apple’s tools. To be a proficient iOS app developer, getting finely acquainted with Objective C is essential, because it is vitally important in all iOS apps and frameworks. In the following parts of this blog tutorial, you will come to learn – how to create simple iOS app and then test it on a device. You will also learn how to submit your app to the Apple App Store.
Highlighting the things that we are going to discuss in the tutorial
- Set Up
- Fundamentals (Tools, Languages & Basis Drills)
- Development (Framework, Design Patterns, Human Interface Design And App Design)
Getting Started For Set-Up
Everything that you require to begin with iOS app development comes in this ‘Set Up’ phase. IOS Software Development Kit (SDK), Integrated Development Environment (IDE) and Xcode are the most crucial things that you need to get conversant with, in order to create outstanding apps for iPhone, iPad and iPod Touch. Xcode is considered to be everything in iOS app development, as it possesses smart features like graphical user interface editor, source editor, workspace window (where you carry out the codes, designing the UI and debugging). To extend the toolset of Xcode, we employ iOS SDK for framework and compilers.
Before you begin with your development, installing the latest of Xcode becomes mandatory. Once the Xcode is successfully installed, you will know that iOS SDK comes preloaded with Xcode.
Nitty-gritty for iOS development
- Tools: You need to be familiar with the leading role of Xcode in the iOS app development realm. Xcode bestow tools that empowers your entire development workflow, i.e. designing the user interface to building your app, optimizing, testing and even for launching your app to the App store. A proficient iPhone/iPad developer knows how to customize Xcode to shape the app.
- Objective C Language: Almost every developer should be acquainted with this object-oriented language C which strengthens all iOS applications. To make the best use of this language, understanding it language in-depth is essential. Even learning this language won’t take much time as it uses syntax and conventions which make it simple to grab. Although you can even learn other programming languages like C++, Java etc., but creating an iOS app without Objective C wouldn’t be possible.
- Basic Drills: Once you are well familiar with Objective-C, you can write basic codes. When you are creating iOS app, you need to know to build objects, relate objects, query objects and access objects. Since Objective-C teaches about objects, you should think about objects in the real world when developing an iOS app. Think about what an object comprises of, the features and scope of it (like what it can do) and how it is connected to other objects.
- Framework: When we talk about core development then coding is what you write. However, if you have a question, the Framework provided by Apple is where you will find the answer to it. For those who are not aware of Frameworks, they encompass a library of methods that can be useful in creating your app. You can get the benefits of a framework through its API (Application Programming Interface). Using a framework not only saves a coder’s time but his or her efforts too!
- Design Patterns: Don’t construe Design patterns as complicated codes but abstract designs which give you a better idea and understanding for creating an app. Design Patterns help you in making more effective use of the framework.
- Human Interface Design: Creating an iOS app is more than an application. This means that it needs to be interactive, appealing and intuitive. The interface should be designed to interact effectively with users to boost the chances of making it a big hit.
- App Design: When constructing the design of your iOS app, you need to be very specific. For example, do you want an app that should run across all iOS devices or any specific device? All these decisions need to be firmly made in the App design phase.
Once the application has been developed, then what? A great app is always tested on actual devices to make it free from flaws and errors. Once the application has been rigorously tested then you can submit it to Apple App Store to get approved.
