With the inception of mobile technology, the whole world has adopted this high-end technology device that becomes the part of modern life. However, it goes without saying that the demand for mobile app developers is extremely high.

Almost all the people depend on this feature-rich device to perform their day-to-day task of booking tickets, paying bills, shopping, entertainment etc. Because of this, mobile app development is the extremely popular career choice for anyone, who is looking forward to breaking into the digital industry – from iOS to Android to BlackBerry.

The mobile app developer has been ranked near the top of just about every legitimate “hot jobs” list for the upcoming year. The U.S. Bureau of Labor Statistics projects incredible growth with estimates running above 20% in the next five years, and in the recent article in Inc., it noted 83,649 app developer jobs posted then people hired.

It means there are enormous opportunities for mobile app developers to make their career in the mobile app industry. As per the recently published article from TekPartners, it has been cleared for the market.

Do you know what it takes to become a successful iOS app developer? If no, you can go through this post and check out 6 top skills that you need to be an expert iOS app developer.

6 Skills to Be An iOS Application Developer

Swift

Since Swift was announced at WWDC 2014 By Apple, it has seen enormous improvements. Swift is the most powerful programming language that has been created by Apple especially for developing their applications?

Every single day, Swift becoming faster, more stable and more fully-featured. It is the language that is full of future development for iOS, so it is important to know it thoroughly.

Various experts have acknowledged it as it is not a small language; however, you don’t have to know everything to land a junior position. All you need to do is ensure that you are comfortable with:

• Basic syntax
• Optionals
• Control Flow (If and Switch Statements)
• Classes, inheritance and initialization
• Error handling
• Objective-C Interoperability

In case, if you are familiar with the programming experience, but want to become familiar with Swift, you can go through Udacity’sSwift Syntax course.

Learn Objective-C

Once you learn about Swift, you will feel Objective-C language as an alien language compares to most languages. As lots of iOS developers only love to get into Swift vs. Objective-C debates online. Here are the reasons why you should learn Objective-C language:

• Tons of GitHub repos written in Objective-C.
• Tons of Stack Overflow questions written in Objective-C.
• Tons of legacy code written in Objective-C.

Are you able to seeing a pattern here? At the time of first learning and you hit a roadblock, would you rather be able to find a time-tested answer with 300 upvotes and solve your problem, or waste precious learning time as you have decided to start with Swift?

If you your main aim is to ultimately become a full-time iOS developer, it is necessary that you learn Objective-C. There are many employers, who are expect you to know it, and a lot of them don’t even care about Swift right now as they think it is not stable to bet their hard-earned business on.

If you have learned Swift language, you can start with Objective-C as you will have an easier yet simple time with it. The language is not going to disappear anytime soon, so learning Objective-C is a goof choice.

Spatial Reasoning

It is highly critical for successful app developers to have an ability to think in 3-D and visualize the spatial relations between objects. You can simply keep at the time of designing interfaces for devices like the iPhones, Apple Watch or the new Apple TV.

You must be cognizant of how users will interact with your application. Therefore, you need to comprehend the different types of controls/inputs obtainable for the different platforms. It is also important to be a user of the devices, you are targeting so that you can reason about them.

Whereas some of the people may more naturally evidence this ability, rest assured it is a learned skill and it can be mastered with practice and through developing real projects.

Design Rules

As you know that successful and popular iOS apps are known and admired for being supremely intuitive. And the reason for this is that these are the apps that adhere to a strict set of design guidelines. How data is stored and showed to the user is handled in a way. To develop your own intuitive apps, it is important to know and comprehend these design patterns.

This is the reason, why you pursue becoming an iOS developer through different programs. The iOS programs can make you learn things like:

•  MVC (Model-View-Controller): It is the cornerstone of any iOS or OSX App, and it defines how data is stored and how it is showed to the user, and how it is updated in response to user interactions.
• Notifications: it is another way of passing information.
• Delegate Pattern: Being a very common way of passing information among objects in Cocoa.

Core Data

Here, you can find subject matter experts had to say about core data ““Learning Core Data is like exercising: the first few days feel like torture, but by the second week, you can’t believe you lived without it!” Core Data is importantly the persistence framework for Apple devices, so imagine if every single you are making use of the app, your data was lost.

It would be like the early days of video games where you had to beat Super Mario Brothers in one run since you couldn’t save progress. For storing data on Apple devices, core data is the most important framework. And you can find the best course on it, so you can attain course to get more information.

Grand Central Dispatch

GCD (Grand Central Dispatch) is also known as colloquially. It allows you to add what’s called concurrency to your apps, thereby making it possible for varied tasks to run simultaneously with ease. Do you know why it is important?

Today, apps are doing a lot like pulling data from a network, showing information on the screen, reading touch inputs from the user, running these things at one time would put incredible strain on the user’s phone. It would run either slowly or crash. Therefore, it is must that you learn more about concurrent programming, so you don’t cause crashes.

So, these are the top 6 skills to become a successful iOS app developer, who has ability to develop all types of iOS applications. If you have any iPhone app idea in your mind that you wanted to turn into reality, you can hire an experienced iPhone app development company that has a professional team of iPhone app developers.
