Creating custom operators in Swift
Blog post from LogRocket
Operators in Swift are fundamental constructs represented by symbols, used to perform various operations such as logical, computational, or assignment tasks. These operators can be categorized into unary, binary, and ternary types based on the number of operands they act upon, and their notation can be infix, prefix, or postfix. Swift also prioritizes operator execution through precedence and associativity rules. Common Swift operators include assignment, arithmetic, logical, comparison, ternary, nil coalescing, and range operators. Furthermore, Swift allows the creation of custom operators for specific needs, such as defining a new operator symbol, extending functionality for custom classes or structs, or overriding existing operators to tailor their behavior. Custom operators can have specified notations and precedence, ensuring flexible and expressive coding solutions. Understanding and utilizing both built-in and custom operators effectively is essential for mastering Swift programming, as they are integral to the language's functionality.
