Inside iOS Dev

In this episode I walk you through how to create an extension on Optional String type to default nil strings to an empty string. This little shortcut can greatly reduce the amount of ifelsing and if let unwrapping on optional strings in your Swift codebase.

I'm transitioning to Youtube! Don't worry, the podcast is not over :) I'll be making more and more screencast style videos instead of just audio podcast format. I'll still be having guest over and have conversations with them about the code and I'll be cross posting screencast episodes on the podcast as well.

This new direction will allow me to explain the concepts and showcase the code examples better as the audio format can only do so much.

Please hop on over to Youtube. You can find the channel here https://www.youtube.com/channel/UC6zcA3dAMUWN8E2_dlg_WyQ

Please share, like, and subscribe to it as it will greatly help me get this channel up and running. Hope to see and hear your feedback and have better content quality there. Let me know what you think and I'm looking forward to hearing from you!

Alex talks to Sandeep Aggarwal about Builder design pattern. They talk about use cases where the pattern is most applicable and how the implementation they made turned out.

Alex talks about unexpected bugs he encountered with the new iOS release and how replacing a 3rd party library with a built-in Apple implementation is not always the silver bullet.

Alex talks about unexpected intricacies and complexities he encountered trying to determine if a given view controller is visible trying to refresh data every time the user sees it.

Alex gives an introduction to unit-testing on iOS. He talks about what unit-testing is, how unit-tests are structured, and best practices on organizing your test code. He also touches upon mocking/stubbing and testing side effects as well.

Daniel Hall and Alex talk about protected visibility modifier in objective oriented languages and how they wish it was added to Swift language. They talk about reasons for why it is needed and what workarounds you could use to achieve semi-similar result.

Alex talks about why he’s been missing in action and haven’t published any podcast episodes in a while.

Alex talks to Tom Mornini about the Law of Demeter and asynchronous programming, Go language, inexperienced developers, SOLID principles, MVC, Ruby on Rails, naming things, polymorphism, and much more.
