Swift Chaining Commands

I'm attempting to chain some commands with casts in swift. Anyone know why the below happens? The variable assignment portion works fine, but if I try to chain them together, it produces compile errors that seem unfixable.

var tempArr = JSONDict["years"]! as [AnyObject]
var tempDict = tempArr[0] as Dictionary<String,AnyObject>
var tempString = tempDict["year"]! as String
var tempInt = tempString.toInt()
var year = (((JSONDict["years"]! as [AnyObject])[0] as Dictionary<String,AnyObject>)["year"] as String).toInt()

Thanks in advance!

Solution

  • You are missing ! after ["year"]

     var year = (((JSONDict["years"]! as [AnyObject])[0] as Dictionary<String,AnyObject>)["year"]! as String).toInt()
