Option 1
let intNum = Int(Float(floatstring)!)
Option 2
if floatstring.rangeOfString(".") != nil {
let i = Int(floatstring.componentsSeparatedByString(".").first!)
print(i)
}

It should work like this:
http://swiftlang.ng.bluemix.net/#/repl/57bd6566b36620d114f80313
let floatstring : String = "23.24"
print(Int(Float(floatstring)!))

You can cast the String to a Float and then to an Int.
if let floatValue = Float(floatString) {
if let intValue = Int(floatValue) {
print(intValue) //that is your Int
}
}
If it does not print anything then the string is not a 'floatString'. Btw you can simply find the answer by combining the answers to these Questions.

1.For Swift 2.0
let intValue=int(float(floatString))
2.For Older version of Swift
let floatValue = (floatString.text as NSString).floatValue
let intValue:Int? = Int(floatValue)
3.For objective-C
floatValue = [floatString floatValue];
int intValue:Int = (int) floatValue;

Try This
let floatValue = "23.24".floatValue // first convert string to float
let intValue:Int? = Int(floatValue) // then convert float to int
print(intValue!)
print(Int(Float(floatstring)!))
