Can anyone make this line of swift into swift 2.0? currentNumber * 10 + Float(sender.titleLabel!.text!.toInt()!)

currentNumber = currentNumber * 10 + Float(sender.titleLabel!.text!.toInt()!) im making a calculator and this is the line of code stopping me.

Hello:

Quick question, what version of swift are you using ?

Try this 

currentNumber * 10 + Float(Int(sender.titleLabel!.text!)!)

My question is, why are you changing it from Int, to float ? I think you can do something like this, and skip the int casting. 

currentNumber * 10 + Float(sender.titleLabel!.text!)

Good luck let me know if it works.

The first line of code works for my calculator, but the second line doesnt let my buttons display anything on the label. And i was wondering if there are any good guides for making a calculator with all basic functions + more using swift 3? I cant seem to find any.
