In this episode Alex and Sandeep react to WWDC 2022 Platform State of The Union. This is our very raw, unresearched reaction/opinion on what we heard on latest WWDC changes for iOS development. Some things are just emotions and unfiltered opinions, some are things we already looked into. We'll be doing deep dives in other videos into some of the stuff we covered that we're not sure or don't know much about or stuff that deserves more attention.

In this episode Sandeep and Alex showcase how mocks can be used in production code to substitute upcoming unfinished or unreleased backend changes. They use dependency injection and Liskov Substitution Principle to inject a service object implementation that uses local hardcoded data instead of fetching it from the network.

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!
