Jon Reid head shot

​Jon Reid

​Technical Agile Coach — Quality Coding, Inc.

​Jon Reid is a leading expert in unit testing and Test-Driven Development for iOS development. He has been practicing TDD on Apple platforms since 2001, and is the author of iOS Unit Testing by Example: XCTest Tips and Techniques Using Swift.


​Jon introduced Test-Driven Development to the team and led by example. I've never seen anyone refactor the large code-base that we had and contribute to new features at the same time.
​Bagath Pugazhendhi — ​Engineering Manager
​Jon showed me how to apply many of the concepts about unit testing to iOS. ​Jon is one of the few who knows the stuff and knows how to explain it. My customers value my knowledge about testing and it is always a differentiating factor with my competitors.
​Jorge D. Ortiz-Fuentes — ​Instructor & Consultant
​Jon demonstrated each TDD step, Red, Green and Refactor, with good and practical examples. ​It's THE best TDD session I ever have had.
