I'm getting no console output for this line of code: println("To build an iPhone app we need to learn \ (modernProgra

Hi Brian,

If you are using an updated Xcode (v7 or v7.1) you will be given an error for using println.There should be a red marker to the left of that line of code in Xcode. Clicking that will give you a "fix-it" option of using print instead. Select that option.

Then, as Ghaith has pointed out, you have a space in between your backslash and the opening bracket.

The lines of code should look something like:

var modernProgrammingLanguage = "Swift"
print("To build an app we need to learn \(modernProgrammingLanguage)")

That works fine. The output may not appear in the 'Assistant Editor' as the course envisages. If you go to View | Debug Area and select Show Debug Area, you should see your output in there.

I hope that helps - else shout back.

Steve.

Neither the console nor the Debugger is reconizing my code. It says theres an invalid redeclaration of the var modernProgrammingLanguage. Any ideas?

var str : String = "Hello "

let modernProgrammingLanguage : String = "Objective C" // SRH This is duplicated below

var greeting = "\(str) + \(modernProgrammingLanguage)" // implicit type string or inferred type of String


var modernProgrammingLanguage = "Swift"   // SRH same variable name *declared* a 2nd time.
print("To build an app we need to learn \(modernProgrammingLanguage)")
