Swift Convert number to text

Question

let winddir  = jsonResult["deg"]? as? Double
var val = ((winddir! / 22.5) + 0.5);
var arr = ["N", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW"];
return arr[(val % 16)]
println(arr)

Results in 'String' is not convertible to '()' with the line return arr[(val % 16)].
I am sure I am just missing one simple thing but I am stumped.

Answer 1

One certain problem and one likely—you need to use an Int for your array index:

return arr[Int(val % 16)]

The error message sounds to me like you didn't declare a return type for your function:

func getWindDirection() -> String {
    // ...
}
