Assigning a Double to a TextField in Swift.

Hi All,

I would like to take a Double value and place it into a UITextField. I understand I need to convert this Double into a String before doing that.

How do I do that? Is this possible?

Hope someone can help.

Thanks.

You can try something like this

let str = NSString(format: ".2lf", 3.1456)

try the following link to get more of an understanding of the format specifiers xcdoc://?url=developer.apple.com/library/mac/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html#

Thanks for your help. That makes sense.

My code would be this - 

var revenueString = String(format: "%f", revenueFloat)

Now the 'revenueString' variable is a string value of the 'revenueFloat'. But I want the 'revenueString' to be displayed in a UITextField.

What is the syntax for that?

Hope you can help me.

Thanks,
