Swift Programming Language – Guide for Those Familiar with Other Languages (2026)

This Czech-language book introduces Swift, Apples modern object-oriented programming language, to programmers who already have basic knowledge and experience with another object-oriented language, such as Python, Java, C++ or C#. It highlights the differences between Swift and these languages without lengthy explanations of basic concepts such as variables, conditions or objects. The book offers a concise, practical look at Swifts approach, explaining why the compiler prevents even basic implicit conversions, why Swift has neither abstract classes nor a traditional garbage collector, and what it means to work with a rigorously strict type system. It also explains protocol-oriented programming, the advantages and potential difficulties of value types, and why arrays and dictionaries behave differently in Swift than in other languages. Finally, it presents Swifts key strengths and weaknesses and shows how the languages historical development has influenced its current position among modern programming languages.
