Description
This rule encourages the use of the first(where:) method instead of chaining filter followed by first when searching for the first element that matches a condition. Using first(where:) is more efficient because it stops iterating as soon as it finds the first matching element, whereas filter evaluates the entire collection before extracting the first element.
To comply with this rule, replace code like bar.filter { $0.containsString("baz") }.first with bar.first(where: { $0.containsString("baz") }). This not only optimizes the code but also enhances readability and maintainability.
