Apple introduced CloudKit in 2014. Since then, it has received many improvements, like the ability to use it outside Apple’s platforms and to use it on apps distributed outside the App Store on the Mac.

Scripting and Compiling Swift on the Command Line

Apple’s Swift programming language is most widely used for iOS and macOS development in Xcode, however, it can also be used in a manner more like a traditional Unix shell script or even compiled into an executable using the command line. Below, I give some examples of these alternative uses.

Anonymous nil

Anonymous nil is a subtle code smell that is present in many codebases. What is it? Why is it a problem? How can we solve it? Let’s take a brief, made up and very contrived example. Let’s say there is a method in your codebase that shows view with an animation.

Break Out of reduce

reduce is a very useful method in Swift Standard Library. It works like a for in loop (it is the one in fact), but it’s designed specifically to calculate a single value out of the elements in the collection… There is only one difference.

Stupid Swift Tricks: Sleepsort

Was chatting today about the freestanding old style partition function and the new one that’s part of SE-0120. One thing led to another and I was writing sleepsort in a playground.

iOSCon 2017 - The conference for iOS and Swift Developers

You can watch all talks in the conference here.

Everyday Reactive

In this talk, we’ll walk through some practical uses of reactive programming in app development, using examples from my daily experiences. We’ll explore tips and tricks for determining when reactive programming can be a potent tool, as well as scenarios to avoid that might threaten code quality and performance. The talk will focus on concepts in reactive programming, the code will show off different Swift reactive implementations.

Reduce Build Times and Get Home Eariler

In this session, I will show you how to improve Swift’s build times and gain productivity in three parts: Measurement, Improvement, Avoid building all together!
