Introducing ObjectiveKit — Remember the big Dynamism-in-Swift debate of May 2016? If not, here’s a quick refresher: Dynamic Swift Brent Simmons (see archive for more): In case it's not clear: with recent and future articles I'm documenting problems…mjtsai.com In short, the argument is that there are many types of problems that developers are currently solving with the dynamic features of the ObjC runtime. …

Multi threading and concurrency are essential for the modern app …and yet Grand Central Dispatch, the system level library for managing concurrent operations, has one of the more cumbersome and unfriendly APIs in the iOS SDK. No more. Swift 3 brings with it many improvements to Grand Central Dispatch syntax…

Yesterday, the first day of WWDC, was full of exciting improvements to all of Apple’s platforms. For me, the most impressive update of all was to animations in UIKit. Meet the brand new UIViewPropertyAnimator. Until iOS10, performing gesture-based and interruptible animations on iOS was a pain — often requiring a…

Introducing FileBrowser — Last month I released an open source iOS framework for zipping and unzipping files called Zip. For Zip’s example project, I wanted a quick Cocoapod that will display the file system with a nice UI and will let users use and observe Zip in action. …

A brief tutorial — C is 44 years old. While that may sound like an ancient age for a programming language, C doesn’t care. It’s as energetic and as essential as ever. Yes, it might not be as ‘sexy’ as Swift or Go but it’s still often the best way to perform some low…

Introducing Zip, an iOS framework for working with Zip files. — One of my favourite Objective C frameworks is SSZipArchive - it’s a very useful wrapper on top of minizip, an open source C library for zipping and unzipping files. Last year I released a couple of Swift frameworks to help with phone number parsing and more general localization. For my…
