BIG HEART APPS
Whether you're first starting out or a seasoned professional, I highly recommend getting your hands on a book that will teach you the fundamentals and principles of software development. SwiftUI Essentials will get your started with the latest version of Swift and the newest technologies. It's one book that I can't put down because it's easy to read and contains practical examples, guaranteed to help you progress as a Swift developer.
The Clean Coder is also another one of my favorites. As engineers, we strive to become better and efficient programmers as well as time managers. We want to learn to write clean and testable code, provide accurate development estimates, to commit to the right amount of work, and to learn when and how to say no to work that is too far-fetched. Robert C. Martin teaches what he's learned throughout his years as an engineer and provides great inside on what it takes to become a truly professional engineer.
