Today’s article is all about facial recognition technology. Despite all of the limitations of facial recognition, such as variations in posing, lighting and image quality, the technology is gaining in popularity and eventually will become a part of users’ everyday lives. In this article, Nataliia Kharchenko and Illia Chemolosov decided to share their experience of dealing with facial recognition algorithms and engines and things they’ve learned.

Air quality is a serious and complicated issue. It’s not as easy to understand as the weather. However, by creating a variety of quick iterative prototypes — regardless of how fake — Geof Crowl was able to find straightforward answers to design and program my iOS app Air Lookout.

Developing for macOS using Swift has a lot more in common with iOS development than you realize. To prove this, Marc Vandehey will walk you through building a simple screen-annotation application. Once completed, you will realize how easy it is to build applications for macOS. This app is pretty short and sweet, but you will learn a few things. By the end of this article, you will become an Apple developer. Congratulations, and happy programming!

In the previous article, David Tucker introduced the concept of user management and how complicated it is in our current digital landscape. If you regularly create new web or mobile applications, then Amazon Cognito is a powerful tool that can cut 90% of the time it usually takes to set up a custom user-management solution. David believes that whether you are a web, iOS or Android developer, this toolset will prove to be a valuable one. Feel free to use the sample code to help you in that process. Happy coding!

As a developer, David Tucker often runs up against one hurdle that can slow down the initial build of a mobile hypothesis: user management. Cognito is a tool for enabling users to sign up for and sign into web and mobile applications that you create. In addition to this functionality, it also allows for storage of user data offline, and it provides synchronization of this data. In this article, David will walk you through the process of configuring a user pool for your needs. Then, he will integrate this user pool with an iOS application and allow a user to log in and fetch the attributes associated with their user account.

With iOS 10.3, Apple has gifted the world powerful new features, as well as fixes for critical security holes. For your typical iPhone user, it’s a really nice upgrade. For a software developer who is responsible for either a mobile website or a native app, it can be a huge pain, because Apple changed the confirmation alert into a new non-blocking dialog. For developers, there is a hidden change that has more important implications: the App Store had always received a special exemption from the old version of this alert, but that exemption has now been removed.

Evgeny Khrolenok and Igor Mikheiko thoroughly studied the features of the human visual apparatus and the technical details of stereoscopic photography. They decided to develop an iOS app to shoot 3D videos and upload the videos to YouTube. The idea behind the app was to facilitate the shooting of 3D video by mounting two iPhones to a special frame — and they did it! In this article, Evgeny and Igor share their lessons learned while developing an app to help folks create their very own 3D stereo videos.

In the past 10 years, a big portion of the Apple’s Worldwide Developer Conferences has been devoted to iOS. This is where we learned about the first iPhone SDK, notifications, share and today widgets, the iOS 7 redesign, iPad multitasking, and other iOS milestones. I was genuinely surprised with some of the announcements this year. In this article, Lou Franco brings you his overview of what happened this WWDC season, with code samples. If you want to try out any of the sample projects, you are going to have to update your Mac to macOS Sierra 10.12.5 (the latest point release), and have Xcode 9 installed.

Imagine that you get up to get a glass of water, but the exact reason why you did that at that particular time isn’t easy to explain. It was “too hot” and you were “somewhat thirsty,” but also maybe “a little bored.” Each of these qualities isn’t either/or, but instead fall on a spectrum of values. In contrast, software is usually built on Boolean values. You set isHot to true and if isHot && isThirsty && isBored, then you call getWater(). If you use code like this to control your game characters, then they will appear jerky and less natural. In this article, Lou Franco will show you how to add intelligent behavior to the non-player characters of a game using an alternative to conventional Boolean logic.

Apple’s GameplayKit has several algorithms and data structures that make it easier to follow game development best practices. When you develop a game, you need to sprinkle conditionals everywhere. If Pac-Man eats a power pill, then ghosts should run away. GKRuleSystem, lets you build up complex conditional logic from smaller pieces. By structuring your code around it, you’ll create rules that are easier to change or reuse for new levels. In this article, we’re going to take typical game logic code and learn how to represent it as a rule system.
