Hello Steven,

If I understood, in your first question you wants to name a variable dynamically based on an user input, right?

So, I think that it is not possible, because your variable name is defined before the app is compiled and the user input is provided in runtime.

For your second question, about store an UITextField string inputed by the user in a variable using Swift, I think that the code below will help you:

var userInput = self.myUITextFieldIBOutlet.text

If you wants to guarantee that the user has provided an input you can check if the UITextField is empty, try this code:

if (self.myUITextFieldIBOutlet.text.length == 0) {

println("The user not entered any text in the UITextField")

} else {

//You can store the user input in the variable
var userInput = self.myUITextFieldIBOutlet.text

}

I hope that my answer helped you!

Best Regards,

(Sorry if I made any grammar mistake, I'm just learning english :))

Thanks. When I click on a tableview cell, I made it so I am taken to another viewcontroller. Do you know how I can reference the value that was in the tableview cell in the other viewcontroller. Filipe Alvarenga
