One of the most exciting parts of Swift being open-sourced is that it can be used as a more general purpose programming language. Server side Swift is an especially appealing platform given the web’s ubiquity. Recently, Apple began to support this initiative more formally by creating a working group dedicated to Swift on the server. We at Big Nerd Ranch are very excited to see Swift on the server.

This post was adapted from a talk called “String Theory”, which I co-presented with James Edward Gray II at Elixir & Phoenix Conf 2016. My posts on Elixir and Unicode were also part of that talk. IO Lists and Phoenix In my last post, I showed how Elixir’s IO lists enable us to build and write output with minimal work and memory usage. This is nice enough for writing files, but it’s absolutely kill

Elixir and Unicode, Part 2: Working with Unicode Strings This post was adapted from a talk called “String Theory”, which I co-presented with James Edward Gray II at Elixir & Phoenix Conf 2016. In my post on Unicode and UTF-8, I showed you the basis of Elixir’s great Unicode support: every string in Elixir is a series of codepoints, encoded in UTF-8. I explained what Unicode is, and we walked throu

[Updated] Splash Screens the Right Way Launching a Splash Screen Update Splash screens are a big deal for Android developers. In fact, BNR’s VP of Engineering, Chris Stewart, wrote our original Splash Screens the Right Way blog post over five years ago and it is still our most popular post. We’re aiming to update the implementation with modern Android practices and to fix a bug in the original pos

Code completion can improve your productivity by reducing how much you have to type, but there are situations when a more powerful tool is needed. Thanks to Android Studio and IntelliJ, live templates make it much easier to focus on just the things you care about. Live Templates Live Templates are code snippets that I can insert into my code by typing their abbreviation and pressing tab. They live

Building an iOS App in Rust, Part 1: Getting Started with Rust Editor’s note: This is the first post in our series on building an iOS app in Rust. The vast majority of apps that get developed for iOS and Android are written in the native languages provided by the platform: Swift or Objective-C on iOS, and Java on Android. I don’t expect that to change any time soon; however, sometimes there’s a ne

Triumph! Android Studio 1.2 Sneaks In Full Testing Support I’m calling it. We’ve been monitoring the state of testing in the Android world for some time now, waiting for the day when testing would be fully baked into the Android development cycle. Well, that day has finally arrived. I wrote about setting up unit testing in Android Studio back in January. If you were committed enough to get through

Our engineers’ brains in book format Outside of our bootcamps and corporate training classes, our guides are some of the best resources for programmers looking to jump into mobile app and web development. Designed like our classes, our books provide challenging, accessible, and amazingly practical training to get you writing code quickly and effectively. And what you learn will last you for years

Fragments have started to garner a negative reputation in the Android community, despite being officially supported by the Android team at Google, and there are a host of reasons why: We have to rely solely on default constructors, rather than custom constructors. Nested Fragments are prone to bugs and limitations. The Fragment lifecycle is complex. But perhaps most importantly, Android developers

Can’t get enough info about iOS 8? Join us for our one-day iOS 8 bootcamps in cities across the U.S. Core Data has had a polarizing effect within the development community. You’d be hard pressed to meet a Cocoa developer who is completely ambivalent to the topic. I won’t mask my opinion: I am a true fan. I believe that Apple has made significant improvements to the framework each year. This year w
