Hey :

Ok so the challenge wants you to create a function, with a println method in it. Remember that when creating a function you have to start with the "func" word, then whatever parameters are required IF any, and a return type.

This challenge does not require parameters nor a return type. 

func greeting(){ // NO parameters, and no return type.
println("Hello")

}

// The body of the function, is where you implement it's functionality. 
// So anything that goes in between the curly brackets, is what makes the function work. 
// In this case, it's just a println() method.

Good luck.
