iOS

iOS is what started the smart-device revolution, and people who know how to work with it are in high demand. Here you’ll find stories on development, new products, trends and advice for those who want to break in.

How One Line of Code Forced a Full OS Release

Posted In C++/C#, iOS, Working in Tech
iPhone Update
It’s not often that Apple ‘fesses up about a bug, but the release iOS 7.0.6 came about because somehow an extra line of code got added to a function and broke it. Normally a bug would probably not warrant a complete release, but unfortunately this one-liner broke SSL connection verification. This is the code that checks that the connection is talking to the correct destination and uses SSL and TLS to verify it. You can take a look at the… continue…

Amazon Offers Developers Better Cross-Platform Tools

Amazon Analytics
Amazon wants integration with its services to be easy for developers and consumers alike, so it’s enticing developers to create better cross-platform experiences by opening GameCircle, Whispersync, Analytics and in-app purchasing to new platforms. So now developers can take advantage of Amazon services on mobile (Android, iOS) and desktop apps (Mac, Windows). iOS is limited to GameCircle, Whispersync and Analytics. The hoped-for result: Developers have a stable back-end platform while Amazon consumers get a frictionless buying process. Extending Amazon’s application… continue…

Programming for iOS With Xamarin Studio

Back at the start of July I began a contract to develop an iOS app for a Taxi firm. I decided to invest in Xamarin Studio so that I could develop the app in C#. The development took a bit longer than expected due to issues with the server, but it’s now very near completion. Xamarin, while appearing to have come out of nowhere, is actually a renamed and rebranded version of MonoTouch, so it’s a couple of years old… continue…

Can Mobile Move Beyond Hardware and Software?

We’ve seen smartphone and tablet specs ramp up sharply lately, with quad-core processors, gigabytes of memory, continuously evolving — even open — operating systems and ever larger physical dimensions. So the question is: What’s next? If you’ve purchased a smartphone lately, the changes are ho-hum. Developers have picked up where enhanced performance left off by introducing a steady stream of new applications and services. We seem to have an app for everything now. Yawn. Fortunately, manufacturers are breaking out of… continue…

Video Conferencing Has Potential for Mobile Developers

Video Chat
Look around your office and tell me how many people are using video conferencing on their smartphone. How about in the park or at the coffee shop down the street? I’d guess not that many. You’d have thought that by now — with all the hype from Skype, Google, Apple and Samsung about multi-mega pixel back and front cameras on smart phones — that we’d have abandoned the old “cell-phone to the ear” method of talking to someone in favor… continue…

Tech Interview Questions for iOS Developers

Dice Interview Qs Icon
While some managers ask code-oriented questions to assess a developer’s proficiency with iOS, others like to explore their knowledge of advanced algorithms first. So how do you know which type of test you’ll receive? “Ask if you’ll be taking a computer-based exam,” suggests Eric Schweitzer, guide of the Dice iOS Talent Community. “If so, you should refresh your knowledge of algorithms and be ready to write some code.” To help you prepare, we asked Schweitzer to share a few code-oriented… continue…

Apple Hiring Engineers for Maps App

Posted In C++/C#, iOS, Looking in Tech
Apple Thumb
Apple’s throwing more weight behind its effort to douse the firestorm of criticism that erupted over its mapping debacle. It’s currently looking to hire C++ and Linux engineers who’ll be tasked with integrating transit routing information into its Maps services. Although Apple is currently looking only for a Maps C++ software engineer for its public transit team and a Maps Public Transit Engineering Manager, it notes that the manager’s time will also be spent on “expanding the team.” According to… continue…

The Challenge of Flat Design

Apple iPhone iOS 7
Like just about every iOS developer, I’ve starting working on updating apps to be consistent with Apple’s latest Human Interface Guidelines (HIG). All previous versions of the HIG strongly recommended skeuomorphic design elements. The latest strongly encourages flat design and strongly discourages skeuomorphism. The reason for encouraging skeuomorphic design was to make the use of an unfamiliar device – a handheld computer with a phone or a tablet computer – more obvious by mimicking devices users would be familiar with.… continue…

Is Developing in Xamarin Better Than Xcode?

Posted In C++/C#, iOS, Working in Tech
Dice News Hangouts
Apple makes its Xcode IDE available for free to iOS and Mac developers. Should experienced C# developers use the cross-platform Xamarin Studio instead? Talent Community Guides David Bolton and Eric Schweitzer discuss considerations such as GUI developers, debuggers and learning curve, as well as the speed of cross platform development, in this Dice News Hangout.

Backend as a Service is Burgeoning

Servers-Thumbnail
Anyone doubting the viability of Backend as a Service (BaaS) only needs to look at Facebook’s acquisition of Parse.com this year and the growth of BaaS over the past eight years. Facebook’s acquisition of Parse.com, for example, allows the social media giant to provide their own backend services for games and applications. Close integration of Parse with the Facebook platform should lead to reduced server latency and greater responsiveness. Parse.com has been described as both BaaS and XaaS (Everything as a Service).… continue…
