Swift - adding values captured in two textfields

I seem to have a problem with a very simple scenario.

I'm trying to add values captured by two text fields (called T1 and T2) and display their total upon pressing a button (GoButton) on a label (Label1).

I tried wording the syntax in multiple ways and it still doesn't work. I feel that some of the syntax I found on the web didn't work for me. I use Xcode 6.3 on Yosemite.

Is there a chance that there is something I'm missing with my Xcode to accept swift syntax? Please help.

Solution

  • Dante- There's still a chance the values could be nil. You've correctly !'ed the TextFields so they unwrap automatically, but the Int conversion is also Optional (the Int still thinks it may get a nil value).

    Label1.text = "\(T1.text.toInt()! + T2.text.toInt()!)"

    Helpful Hint- If you paste your code in here (rather than a screenshot) it's much easier for folks to copy and paste your code into their IDE and test it out.

    For those here smarter than me (everyone) I'm curious why Xcode doesn't complain about a single Int conversion:

    Label1.text = "\(T1.text.toInt())"  // no complaint from the compiler
