Beginners Guide to Learning iOS App Development

When you scroll through the numerous applications on an iPhone, the thought of developing an iOS App would definitely cross your head. iOS mobile Application development is not rocket science, all it takes is little patience, and some enthusiasm to finish it to the podium. However, statutory warning, it’s not that simple either.

Before we start, spend some time on ideation; Why do you need this Application? This is the first and most important step before jumping into developing a mobile App. Think through why you really need to build a iPhone App. Will the mobile App really help the user? Are there similar iOS Apps that does the same thing? It could be very simple or we would require to re-think the way problem is perceived and we need to think from scratch. The whole purpose to ideate before developing a mobile App is to have a clear problem statement and findings of research so that you are always focused on a central problem and user centered.

Once you’ve decided on the Mobile App,

Here are 7 basic steps to start with iOS App Development:

1. Get Familiar with Mac:
iOS development definitely needs a Mac machine. If you are not somebody who hardly never used a Mac machine, you definitely have to get acquainted with one. It will take a couple of days to get really familiar with it. Once you are comfortable, you’ll feel like a rockstar!

You will also require a developers account to get started. It’s a one time cost of 25$. Also, if you want to submit your app to the App Store, you’ll need an iTunes Developer account which will cost you 99$/year.

2. Learn Objective C:
Objective C is the main programming language used by Apple for the OS X and iOS operating systems, and their respective Application programming interfaces (APIs). It’s a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language.

Like C++, Objective-C is designed to add object-oriented features to C, but the two languages accomplished this using fundamentally distinct philosophies. Objective-C is decidedly more dynamic, deferring most of its decisions to run-time rather than compile-time. This is reflected in many of the design patterns underlying iOS and OS X development. Objective-C is also known for its verbose naming conventions. The resulting code is so descriptive that it’s virtually impossible to misunderstand or misuse it.

Here are some links to good books to learn Objective C:

3. Learn IDE – Xcode
The Integrated developer environment (IDE) for iOS App Development is Xcode. You can download it for free from the App store. When you open it for the first time, you will be asked if you want to start a new project or open an existing project or open a random editor to code whatever you feel like. Start with the basics of Objective C. Play around with simple input output programming lines. Gradually move to strings, numbers, arrays, conditional functions, etc.

To learn Xcode, here are couple of links to learn Xcode:

4. Start With Simple Projects
Do simple projects on Xcode. Start with simple programs like calculator, average of a student, emi calculator, area of a quadrilateral. Once you accomplish these simple programs, you’ll slowly grow on confidence. Get excited in writing codes for the everyday things that you see around. Once you start mastering it, you’ll feel that you can write almost everything that you see around into a programming code. That’s the level that you need to grow into. You have to breath it.

5. Learn to Design The User Interface:
Developing a mobile App is not, like I said earlier, rocket science. With basic intelligence, almost anybody can do it. However, becoming the best iOS App developer is an art that you need to master. Only think of how the App looks like for a user. The thought process of the user, the colors that are used, the placement of buttons, the number of pages, the level of details of colors, the art of simplifying the content, providing content that is only necessary for the user, etc. This is definitely a long list, but, you’ve to think only from the perspective of a user; the factors that gives a user the best mobile experience! When it matters, go micro level of detailing and perfecting the user interface. Be perfectionist when it matters for User Interface. And that’s how you can eventually give the best user experience to your iOS mobile App users!

6. Database:
This is where the coding gets serious. You will have to start using database to store data. Storing data has always been challenging. Be smart in matters to databases while making your mobile App. Store content in a simple way without complicating it so that when you need to use them or access it, it’ll be super easy for you. Get acquainted with SQlite, Plist, etc.

Once you build your mobile App, do a good quality analysis of it. It’s necessary to test your App to ensure that there are no bugs, and no coding errors. Use Xcode Instruments to test your iOS App. It’s very easy to use, and you can test the performance, memory usage etc of the App.

Here is a tutorial for using Xcode Instruments:

In short, take it slow and get excited when you want to build any mobile App. Keep the enthusiasm going whenever you want build a mobile App. Start with small projects and small Applications and master all off it. Build more exciting and challenging Applications. Read developer forums, share ideas, and learn what other iOS developers have to say. There might be simple hacks for lengthier code lines. Learn, share and care to become the best iOS mobile App developer. Go get ‘em champ!
