Implementation

To add SimpleSwiftCalculator import the SimpleSwiftCalculator.swiftfile into to your project and make sure that your receiving UIViewController class complies with the PushResultsDelegate protocol by adding the PushValueFromCalculator function:

    class ViewController: UIViewController, PushResultsDelegate {
         func PushValueFromCalculator(value: String){
            // value is a string value of the current operation's result
         }
    }

You can then display the calculator whenever you want:

     let CalcInstance = SimpleSwiftCalculator(frame: CGRect(x: 0, y: 0, width: YourWidth, height: YourHeight))
     CalcInstance.becomeFirstResponder()
     CalcInstance.isUserInteractionEnabled = true
     CalcInstance.delegate = self
     self.view.addSubview(CalcInstance)
