Read moreWhy Swift is protocol-oriented programming?
Swift checks for protocol conformity issues at compile-time, allowing developers to discover some fatal bugs in the code even before running the program. Protocols allow developers to write flexible and extensible code in Swift without having to compromise the language’s expressiveness .
Read moreWhat is difference between object oriented programming and protocol-oriented programming?
In the object-oriented paradigm, we focus on what an object is, while the protocol-oriented approach allows us to focus more on what an object can do, its abilities and behaviours. Our simple game was meant to emphasise differences in structuring decisions during the development process using both of these paradigms.

Read moreWhy are optional Swifts good?
Swift’s optionals are one of its most powerful features , while also being one of the most confusing. Their core job is simple: they allow us to represent the absence of some data – a string that isn’t just empty, but literally doesn’t exist.
Read moreShould I use optional chaining?
