At Google I/O 2018 , Google announced a new way to present UI templates that can display rich, dynamic and interactive content from your app within the Google Search app and, later, in other places such as the Google Assistant . Those UI templates are called Slices . The templates are great for many reasons: Slices can help users to get information or take instant action outside of an app screen. Slices make your users re-engage with your app in a relevant context. Slices are built into Android Jetpack and can extend all the way back to Android Kitkat API 19. Slices are in beta release at the time of writing this tutorial, but you can get started developing with them today! Getting Started In this tutorial you are going to build a Slice template for a raywenderlich.com Bookstore app. The Slice will display some book covers with titles and prices, as well as a notification icon to enable or disable the app notification. Here’s what the end product will look like: Prerequis...

Hey, Swifties! The full release of our Data Structures & Algorithms in Swift book is now available! The early access release of this book — complete with the theory of data structures and algorithms in Swift — debuted at our conference RWDevCon 2018. Since then, the team has been hard at work creating a robust catalogue of challenges — 18 chapters in all — to test what you’ve learned and grow your expertise. The book is structured with the theory chapters alternating with the challenge chapters to keep you on track to nail down the fundamental and more advanced concepts. Why Do You Need This Book? Understanding how data structures and algorithms work in code is crucial for creating efficient and scalable apps. Swift’s Standard Library has a small set of general purpose collection types, yet they don’t give you what you need for every case. Moreover, you’ll find these concepts helpful for your professional and personal development as a developer. When you interview for a softw...

Update note : Ehab Amer updated this tutorial for Xcode 10 and iOS 12. Bjørn Ruud wrote the original. One of the coolest things about iOS apps is how animated they are. Views can nimbly fly across the screen, gracefully fade in and out, cleverly rotate around and rescale, and much, much more! UIView animation is everywhere in iOS, and it’s a big part of what makes iOS apps so much fun. Thoughtfully chosen animations look great, and they can really bring your own iOS app to life. Better still, they’re also a great way to draw a user’s attention any time new or additional information becomes available in your app. But maybe the best part about UIView animation is that it’s incredibly easy to implement. All it takes is a few lines of code, and you’re up and running! In this tutorial, you’ll get a chance to go hands-on with UIView animation! You’ll create a simple app with a picnic theme: You’ll use animation to open the picnic basket, animate an interloping bug that’s snuck into the ...
