Summary:
When unit testing code you often want to test whether an optional is not nil and has a specific value. Currently the only option is to use code like the following
// Given an optional a
if let a = a {
	XCTAssertEqual(a.value, 3, "Value should be 3")
} else {
	XCTFail("A should not be nil")
}

Steps to Reproduce:
Have a look at the attached sample project

Expected Results:
There should be an easy method to test that the object is not nil and performs the test if this is the case. An implementation could look like the following:

func XCTAssertEqual<T: Equatable>(expression1: @autoclosure () -> T?, expression2: @autoclosure () -> T, message: String) {
	let evaluated1 = expression1()
	if let evaluated1 = evaluated1 {
		XCTAssertEqual(evaluated1, expression2, message)
	} else {
		XCTAssertNotNil(evaluated1, message)
	}
}

Actual Results:
A method like the one described above has to be created by hand which shows the failure messages at the wrong line of code or the cumbersome if-else construct has to be used
