iOS: Everything You Need To Know About Coding Apps

iOS: Everything You Need To Know About Coding Apps

September 12th sees the unveiling of the new iPhone. Currently, there is a lot of speculation as to what new features the specification will include, and rumours are flying around on what the new handset will look like

. The latest release is also set to see the upgraded version of iOS. iPhone’s software, iOS, is currently in its tenth generation and, over the course of its evolution, has become one of the front runners for mobile software, second only to Android.

The powerful operating system of iOS runs exclusively on Apple hardware, and currently has over 2.2 million applications that written for it. Used on the iPod touch, the iPad, the Apple Watch and the Apple TV, iOS has sold over 1.75 billion units since its conception in 2007. In addition to this, the operating system has also generated over $1 trillion in revenues over the past ten years. With the applications written for iOS collectively downloaded over 130 billion times, it is a crucial piece of software for potential application developers to get to grips with.

Developing and creating iOS applications wasn’t something that was originally going to be enabled. With the release of the first iPhone back in 2007, Steve Jobs, Apple’s then-CEO, had no intention of allowing third party developers to create content for the device. Instead, he proposed that would-be developers create web applications for users, rather than build native apps for the system. Naturally, this caused a backlash amongst the community of developers, forcing Apple to reconsider.

A year after the announcement of the first iPhone, the Software Development Kit for iOS was released as a free download for Mac users. Today, the iOS SDK allows developers to build applications for use on any Apple device running the operating system, although it is still unavailable for use on a computer running Microsoft Windows.

One of the most common pieces of software that is used in collaboration with the iOS SDK is Xcode, an integrated development environment that includes a host of different tools to aid developing apps. When using the two together, they allow the creation of applications using scripting languages, however, Apple’s own coding language, Swift, is recommended.

Although Swift has been developed by Apple, its open source nature means that it is now available on a variety of different systems, such as Linux. Ted Kremenek, Senior Manager, Languages and Runtimes at Apple says: “A big part of doing that [making Swift open-sourced] was not just to shove out a bunch of sources to GitHub, but to create a fully open community that drives the evolution of swift going forward. Swift 3 is the first major update to Swift that is intended to a product of that community.”

The clear syntax of Swift is one of the benefits of using the coding language to create applications. The language requires less script in order to run simple tasks, which means that it is easier for developers to learn to code with. Those with prior experience in other coding languages, such as Java and #C, will find that the interface of Swift is easy to navigate around, but will also recognise that it is similar to Python.

So how do you go about building native apps for iOS? For those who already have experience coding and, for example, are looking for a range of Java jobs in Ireland, then getting stuck into building apps using Xcode and iOS SDK will be met with ease. With guides on the Apple website about how to familiarise yourself with the tool, you can learn how to undertake a variety of tasks, including creating a simple user interface to defining a data model, before discovering how to design app interfaces.

Have you ever developed an app in iOS before? If so, we would love to hear more on our social channels, so reach out and tell us how you found the development process.

Very professional organisation who have well established relationships with many international companies and Irish public bodies. I discovered they were well regarded by the companies that they deal with. Plenty of support provided for interviews for set up as contractor. Always seem to have a selection of interesting contracting roles.

Brilliant experience with Eolas. Sean Prendergast contacted me with an opportunity. It was a smooth experience from that moment until the end when I landed the offer. Sean swiftly responded to any doubts or concerns I had during the process; made sure everything was transparent and unambiguous all the way through. I would happily recommend Eolas Recruitment for new career opportunities.

Had the pleasure of working with Caroline recently in regard to a new job opportunity. Caroline was professional, attentive, responsive and always kept me up to date through out the application process. Always checking in to see if I needed anything before interviews and following up after. I never experienced this level of support from a recruiter before. It was a lovely personal touch. I highly recommend working with Caroline and Eolas.

I have been working database related contracting jobs with Eolas for a good number of years now. All well done from their end, with no waste of time: Each single interview arranged by them always lead to the next contract - they have always picked the right jobs for what I can do, and they kept me away from what I cannot do. All paper work done immediately. All my questions have been answered straight away. Warmly recommended!

COVID lockdowns in Ireland and the UK might have made the enrolment process more challenging. It didn't! Even a last-minute change to the contract was seamless. Good communication and a simple yet precise set of instructions.What I look for in an employment agency is an invisible partner where everything just works. No trauma. No excuses. Just a bunch of people who know what needs to be done.

I would highly recommend Eolas Recruitment. Sean reached out to me with a role that turned out to be a perfect fit. He knew all the right questions to ask and information to give to establish if the role was right for me at the very start. I found Sean honest, knowledgeable and professional from start to finish, making the process that bit easier. It was a pleasure dealing with Eolas and I would be more than happy to use their services again in the future.

Super prompt, effective communication, transparent and guiding, is what comes to mind while summarising my experience with Eolas Recruitment.It is rare to come by recruitment consultants with a genuine drive to ensure the candidate and the role (vacancy) are a perfect match. I had the pleasure of being guided by Peter Kirby and Caoimhe Cronin trough the hiring process for EY. I see my connection with Eolas to be a longterm and collaborative engagement.

Had a great experience working with Peter. He helped me land my first job in Ireland! Would definitely recommend to anyone who needs help finding a job. Peter was very responsive, and made sure to always check in with me if I had questions or he had any updates on jobs I had applied or interviewed for. Not all recruiters take the time or put in the effort like Peter did. 5 stars all around!
