1. Designing Games with Swift

Why you will love Swift

Beautiful syntax Interoperability Strong typing Smart type inference Automatic memory management An even playing field

Are there any downsides to Swift?

Less resources Operating system compatibility

Prerequisites What you will learn in this book
