Shouldn't call the println directly should be in the body of your function

func greeting() { let greeting = "Hello" println("greeting")

} greeting()

Getting an error that 'Should not call println directly should be in the body of your function.....error

The example code is very different and the exercise badly matches the previous video, can anyone help..... Functions

I don't think you need the quotes (") inside the println function.

func greeting() { 
    let greeting = "Hello" 
    println(greeting)
} 
greeting()

I am glad it did work on Xcode. In the end, that is what matters ;) As for workspaces, I have not tried Swift in it yet. Sorry that I can not help with that issue.

Sorry to be a bother... so I tried this

func greeting() { let greeting = Hello println(greeting) } greeting()

and now I get 'Your code could not be compiled'

swift_lint.swift:8:20: error: use of unresolved identifier 'Hello' let greeting = Hello

Thanks for any help ;)

This is really strange because this works fine for me in Xcode .....

func greeting() { let greeting = "Hello" println(greeting)

} greeting() greeting() greeting()

But it will not work on the treehouse site for the exercise???
