Travel between C/C++ <-> ObjC/ObjC++ <-> Swift

This read me is a scratch paper, I am going to prepare more advance.

print("-- Go To ObjC --")
let calculate = CalculateWrapper()
print(calculate.multiply(5, with: 44))

print("-- Go To ObjC Then Go Back to Swift --")
calculate.greeting(withNumber: 100)

print("-- Go To ObjCpp --")
let person = PersonWrapper()
let name = person.printName()
print(name!)

print("-- Go To ObjCpp Then Go Back to Swift --")
calculate.greeting(withNumber: 500)

print("-- Go Directly to C --")
print(rectangleArea(3, 5))

print("-- Go To Cpp mm Extension Then Go Back to Swift --")
person.sum(ofThree: 3, 4, 5)
