While they share many similarities – both can define properties, methods, initializers, and conform to protocols – their fundamental difference lies in how they handle data: structs are value types, and classes are reference types. Understanding this distinction is crucial for writing robust, predictable, and efficient Swift code, especially in iOS development.
Choosing between a struct and a class isn't just a matter of preference; it impacts…
