I've been making iPhone apps since 2015. My career has included working for a variety of companies - from a few lesser-known startups in San Francisco to well-known companies like Turo, Scoop Technologies, and Porsche. Ever since I created my first Xcode project, I've been maintaining a notebook where I documented everything I was learning. Whether it was a novel code snippet, a particularly challenging bug, or noteworthy insight from a more seasoned engineer - it would all go into the notebook. Now, 5 years later, it is filled with practical tips derived from my day-to-day experiences as a professional iOS developer. It's everything I wish I had known on my first day. Practical Tips for Junior iOS Developers is also a summary of everything I discovered as I transitioned from a Junior to a Senior iOS engineer. We will cover a wide variety of topics ranging from optimal build settings, architecture, and design patterns to Swift best practices and conventions. This book has been fully updated for Swift 5.3 + iOS 14. If you enjoy the free eBook, please leave a review and feel free to connect with me on Twitter at https://twitter.com/aryamansharda :)
