I present an implementation of a a double-ended queue type (deque) in Swift and look at what is required to implement copy-on-write in an optimized way so that this double-ended queue is faster than Array when used as a first-in-first-out (FIFO) queue.

This is a quick look at the changes I needed to make to bring Cocoa with Love up to date for Swift 3 and the latest iOS 10 and macOS Sierra.

A concrete look at the languages studied by the Swift developers when designing Swift's approach to error handling. By comparing these to Swift, I'll try to better understand what balance the Swift developers sought on the topics of feature complexity, syntactic efficiency, abstraction, information signalling and safety.

In this article, I'll discuss the `Result` type in Swift as well as common variations in implementation and approach used for this data type. I'll also look at *why* the type was rejected for inclusion in the standard library and what effect that rejection is likely to have.

I look at usage patterns around timers including some problematic approaches that can make refactoring more difficult, cause strange bugs and otherwise create problems for maintainability.

One of the most annoying problems in Swift is when the compiler gives an 'Expression was too complex to be solved in a reasonable time' error. I look at why this error occurs, how to avoid it and talk about how this should be solved in a future compiler update.

Fun with a pushdown automaton (implemented as a single mighty switch statement) for parsing whitespace in Swift source files. The result is an Xcode 8 Source Editor Command extension for detecting and correcting whitespace issues in Swift files.

I'm going to talk about the absence of any threading or thread synchronization language features in Swift and the concurrency proposal for Swift's future. I'll also try to get a wrapper around different mutex machinery to perform optimally.

I present a few random number generators in Swift and investigate their quality versus performance. I also look at performance implementations and see if I can make a C algorithm run as fast as Swift.

I present an implementation of Swift's Demangle.cpp, rewritten in Swift and use the two versions (the original C++ and my Swift version) to compare the C++ and Swift for writing parsers.
