Swift 'NSArray?' does not have member named 'count'

ios, swift

Solution

`NSArray(contentsOfFile: dataFile!)` returns an optional array. So you have to use like

ropes?.count

Or you can unwrap the `ropes` array first

if let array = ropes{
       for i in 0..< array.count {
       }

    }

Problem

I'm pretty sure `.count` returns the length of an array but for some reason when I used it, it threw a weird error. Heres my code: ``` let dataFile = NSBundle.mainBundle().pathForResource(RopeDataFile, ofType: nil) let ropes = NSArray(contentsOfFile: dataFile!); for i in 0..<ropes.count { } ``` `RopeDataFile` is a constant of a property list that I made earlier. For some reason it gives this error on `ropes.count`, 'NSArray?' does not have member named 'count'. I'm new to swift and sorry if the problem is really simple.
