why is this incorrect... var todo: [String] = ["Learn Swift", "Build App", "Deploy"] println; "todo.count"

Stuck here... Could you explain what I am missing?

thanks, Christian

arrays.swift 
var todo: [String] = ["Learn Swift", "Build App", "Deploy App"]
println; "todo.count"

var todo: [String] = ["Learn Swift", "Build App", "Deploy App"]
print(todo.count)

By putting " " around todo.count you're making it a String, meaning it does not work. Also println was replaced in Swift 2.0 with print()

Am I helping at all :D

thanks for the quick reply!

I realized println is now print —from errors in xcode.

looks like I was missing the "()"

Thanks again
