How can i get the data from Swift based IBOutlet UITextField?

 @IBOutlet  var firstName:UITextField?
 @IBOutlet  var lastName:UITextField?

 let string = firstName!.text
 print(string)

The output is like as below:

Optional("ohh")

How can I get the data without optional text and double quotes?

Solution

  • Your issue is that the text attribute of a UITextField is an Optional - this means it must be unwrapped. To do that, you add a ! to the end, which produces a String instead of a String?.

    You can also conditionally unwrap an optional using the syntax if let, so here it would be

    if let string = firstName!.text{
print(string) //outputs if text exists
}else{
//text didn't exist
}
