About

My name is Bart Jacobs and I run a mobile development company, Code Foundry. I’ve been programming for more than fifteen years, focusing on Cocoa development soon after the introduction of the iPhone in 2007.

Over the years, I’ve taught thousands of people about Swift and Cocoa development. Through my experience teaching, I’ve discovered and learned about the main problems people struggle with.

I created Cocoacasts to offer a roadmap for anyone interested in learning Swift and Cocoa development. Through Cocoacasts, I provide a clear path to learn the tools, the language, and the frameworks you need to master Swift and Cocoa development.

You can find me on Twitter. Follow me and say hi. You can also follow Cocoacasts on Twitter if you’re interested in what I teach on Cocoacasts.

I currently work as a freelance developer and teach people about Swift and Cocoa development. While I primarily focus on developing software for Apple’s platforms, I consider myself a full stack developer with a love and interest for Swift and Ruby development.

Testimonials

Don't take my word for it.

"I actually had several subscriptions prior to this, and I think they served me well as a beginner, but man, cocoacasts is really something else when it comes to introducing more advanced topics. ... Please keep doing what you're doing. You're the only subscription I kept alive because I'm getting so much out of it. Kudos!"

Christian Iñigo De Leon Alvarez

"I think Cocoacasts is the best online iOS Dev training, better than competitors with scores of trainers on their team. Bart manages to keep the videos clear and concise, with the written version alongside. I can't recommend it highly enough."

Andy Pye

"Even though I was already familiar with MVVM, Bart's course showed me a different perspective on MVVM by refactoring a complete application built with MVC. He illustrates how MVVM can improve a project's architecture and testability, and how reactive programming fits in."

Damian Esteban
Chief Technology Officer, betterPT

"Cocoacasts Plus is for me. The content is awesome and the commitment is great. I'm a Mobile Developer Advocate at AWS and my focus is on iOS. I use your best practices when providing samples, tutorials, or writing snippets of code for a blog."

Dennis Hills
Mobile Developer Advocate, Amazon

"It has been a pleasure to work with Bart. I've found him to be diligent, conscientious, and reliable. His own competence has made my job much easier. And his skill as an iOS developer continues to amaze me."

Adam Brown
Code & Mobile Development, Envato

"Bart helped me understand and implement MVVM in an existing project that suffered from Massive View Controller syndrome. We analyzed the problem, developed a strategy, and refactored the view controller, using MVVM and reactive programming. The result is a lean view controller and a focused view model that's easy to test."

Win Raguini
Director of Engineering, MasterClass

"This is one of the finest Swift material available on the internet. Thank you."

Rakesh Kusuma

"A big thank you. This has been the single most effective course I've taken about iOS. I put it into practice right away and our App Store app, and its testing, has benefited greatly."

Jake Young
Chief Information Officer, ACP Decisions

"This is by far the best explanation of Core Data I have read. After working on my first Core Data project for the last three days, I actually understand what you are saying here."

Gravity Zero Design

"Wow, I really love these tutorials. Great job. You are very good at explaining things from the ground up in a way that is both fast (not boring) and yet comprehensive."
