Characteristic	Swift	Crystal
Syntax	Swift has a syntax similar to Objective-C, with a focus on readability and simplicity.	Crystal has a syntax inspired by Ruby, with a focus on simplicity and expressiveness.
Paradigm	Swift supports both object-oriented programming and functional programming paradigms.	Crystal is primarily an object-oriented programming language, but also supports some functional programming concepts.
Typing	Swift is a statically-typed language with type inference, which means that variable types are checked at compile-time.	Crystal is a statically-typed language with type inference, which means that variable types are checked at compile-time.
Performance	Swift is known for its high performance, as it is compiled to machine code.	Crystal is designed for high performance, with a focus on efficient memory management and low-level optimizations.
