iOS 11 sets a new standard for what is already the world’s most advanced mobile operating system. It makes iPhone better than before. It makes iPad more capable than ever. And now it opens up both to amazing possibilities for augmented reality in games and apps. With iOS 11, iPhone and iPad are the most powerful, personal and intelligent devices they’ve ever been.*

Swift 4 is now officially released! Swift 4 builds on the strengths of Swift 3, delivering greater robustness and stability, providing source code compatibility with Swift 3, making improvements to the standard library, and adding features like archival and serialization.

With everything you need to create amazing apps for Apple platforms, Xcode 9 is unbelievably quick and consistently smooth while editing even the largest files. It also understands your code better than ever, so you can select and edit the structure or even transform the selection directly in the editor. Powerful new refactoring tasks happen in place, renaming symbols across Swift, Objective-C, and even user interface files without skipping a beat. And with source compatibility in Swift 4, Xcode 9 uses the same compiler to build existing Swift 3 code and updated Swift 4 code, so you can migrate at your own pace.

In the past two days, I’ve worked on and finished update of one of my apps for iPhone X. There were a few challenges along the way, and that’s where this post comes in.

This post demonstrates an approach for writing reusable Swift code when working with UIViewControllers in an iOS app.

Core Data is not a first-class citizen in the Swift world. Its inherently dynamic nature is lurking at us through an attribute created specifically for it: @NSManaged. Let me show you how this dynamic nature caught me off guard. I ended up with a property having a value I’d never assigned to it!

Recently, I really got tired from MVC and started looking for a new architecture. After a short research, I have noticed the Clean Swift architecture and instantly fell in love with it! This architecture was exactly what I was looking for. 🚀

Continuous Integration (or CI for short) is one of those buzz words that have become really popular lately. It’s the idea that instead of having long-lived feature branches that you use to work on a new feature, you continuously integrate your new code into the project’s main branch (which is usually master or develop if you work with Git). Every time you do so you build the project and run its tests, to make sure everything is in order before merging the change in.

In this video I discuss 20 of the Xcode tips and tricks I use on a regular basis.

When you’re prepping for your technical iOS interview, it is important to understand what topics you could be asked about and what is expected from a seasoned iOS developer. This is a collection of questions a lot of Silicon Valley companies use to gauge the level of seniority in an iOS candidate.
