Swift - Operators and Expressions

You want to overload the == operator for a struct Person to compare two persons by their id. Which implementation correctly achieves this?

Afunc equals(lhs: Person, rhs: Person) -> Bool { return lhs.id == rhs.id }

Bfunc == (lhs: Person, rhs: Person) -> Bool { return lhs.id == rhs.id }

Cstatic func equals(lhs: Person, rhs: Person) -> Bool { return lhs.id == rhs.id }

Dstatic func == (lhs: Person, rhs: Person) -> Bool { return lhs.id == rhs.id }

Step-by-Step Solution

Solution:

Step 1: Recall operator == overload syntax
It must be a static function named == with two parameters returning Bool.
Step 2: Check options
Only static func == (lhs: Person, rhs: Person) -> Bool { return lhs.id == rhs.id } matches correct syntax and naming conventions.
Final Answer:
static func == (lhs: Person, rhs: Person) -> Bool { return lhs.id == rhs.id } -> Option D
Quick Check:
Equality operator overload = static func == [OK]

Quick Trick: Overload == as static func returning Bool [OK]
