Difference
Simple way to identify what is different between 2 instances
Better way to identify what's different between 2 instances. Have you ever written tests? Usually they use equality asserts, e.g. XCTAssertEqual, what happens if the objects aren't equal? Xcode throws a wall of text at you. This forces you to manually scan the text and try to figure out exactly what's wrong, what if instead you could just learn which property is different?
