Before Beta 5 I could use 

var str = "Hello, playground"
str.bridgeToObjectiveC().containsString("Hello")

But this is not longer supported, is there a nice workaround for this, or does Swift already offer it now?

you can use:

var str = "Hello, playground"

if str.rangeOfString("Hello") != nil {
    println("exists")
}

Just cast it explicitly to NSString:

var str = "Hello, playground"
(str as NSString).containsString("Hello")

However if there's a pure swift way to do that, I would use it - it's always better to avoid bridging unless really needed.

In Swift is it called rangeOfString

"hello".rangeOfString("ell")

returns a range

{Some "1..<4"}

You can write extension contains:

extension String {

    func contains(find: String) -> Bool{
       if let temp = self.rangeOfString(find){
          return true
       }
       return false
     }
}

Example:

var value = "Hello world"

println(value.contains("Hello")) // true
println(value.contains("bo"))    // false
