Execution Flow: Quiz I in Swift in Swift

Quiz: What would this code produce if we were to copy-paste it in a code editor and run it?

func welcomeUser() {
	print("Hey coder!")
}
func mainFunction() {
	print("Welcome back!")
	welcomeUser()
}

Important Note:

Do not use an actual code editor to get the answer! It would defy the whole purpose of the quiz!
