import Foundation

operator infix =~ {}


func =~ (input: String, pattern: String) -> String[]? {
    let regex = NSRegularExpression(pattern: pattern, options: .CaseInsensitive, error: nil)
    let results = regex.matchesInString(input,
        options: nil,
        range: NSMakeRange(0, countElements(input))
        )! as NSTextCheckingResult[]

    if (results.count > 0) {
        var values:Array<String> = []

        for result in results {
            for i in 0..result.numberOfRanges {
                let range = result.rangeAtIndex(i)
                
                values += input
                    .substringFromIndex(range.location)
                    .substringToIndex(range.length)
            }

        }
        return values
    } else {
        return nil
    }
}

if let matches = "123alksdjfladskfj3234" =~ "(\\d+)a" {
    for value in matches {
        println("Found \(value)")
    }
}

Thanks! By the way, just to let you know, you should update it to the new array syntax (I.e. [String], not String[] and "..<" not "..").
