Advanced programming constructs and techniques in the Swift language

The thesis focuses on advanced programming constructs and techniques of the Swift programming language. At the beginning programming paradigms that are supported by the Swift design (object-oriented and functional) are introduced. Concepts of each paradigm are described and Swift is then evaluated by the level of support for these paradigms. Following programming constructs are described in-depth: working with variables, optional types, enumerated types, functions and closures. Creating of custom operators and subscripts. Operations with protocols, generic types and parallel program execution. Error handling with throwing functions. Detailed explanation of value types and their differences from reference type is given too. Thesis also explains nested types and all higher-order functions in Swift. At the end are described extensions; specifically extension of computed property, initialization function, function, subscript, nested type and protocol and generic types extensions. In the last section of the thesis these advanced programming techniques are described; function chaining and composition, structure saving, performance optimization of value types, reflection in the Swift programming language and how modules and namespaces work. At the end protocol-oriented programming is introduced
