−
−	~~The equality operator == checks if two instances have the same values for their properties. In order for this to work, the class must conform to the Equatable protocol and implement the == operator:~~

−	~~let instance2 = MyClass(property: 1)~~
−	~~let isIdentical = instance1 === instance2 // false~~

−	Note: It is recommended to use the === operator if you need to check if two instances are the same instance, and use the == operator if you need to check if two instances have the same values for their properties.

		+
		+	In Swift, you can check if two instances of a class are the same by using the equality operator (==) or the identity operator (===).
		+
		+	The equality operator == checks if two instances have the same values for their properties. In order for this to work, the class must conform to the Equatable protocol and implement the == operator:
		+
		+	<syntaxhighlight lang="swift">
		+
		+	class MyClass: Equatable {
		+	let property: Int
		+
		+	static func == (lhs: MyClass, rhs: MyClass) -> Bool {
		+	return lhs.property == rhs.property
		+	}
		+	}
		+
		+	let instance1 = MyClass(property: 1)
		+	let instance2 = MyClass(property: 1)
		+	let isEqual = instance1 == instance2 // true
		+	</syntaxhighlight>
		+
		+	The identity operator === checks if two instances refer to the same memory address. It checks if two instances are the same instance.
		+
		+	<syntaxhighlight lang="swift">
		+
		+	let instance1 = MyClass(property: 1)
		+	let instance2 = MyClass(property: 1)
		+	let isIdentical = instance1 === instance2 // false
		+	</syntaxhighlight>
		+	Note: It is recommended to use the === operator if you need to check if two instances are the same instance, and use the == operator if you need to check if two instances have the same values for their properties.
