Here is a UIBarButtonItem I have:
@IBAction func doneButtonPressed(_ sender: UIBarButtonItem) {
print("doneButton Pressed")
// Guard statement ensures that all fields have been satisfied, so that the JumpSpotAnnotation can be made, and no values are nil
guard let name = nameTextField.text,
let estimatedHeight = estimatedHeightTextField.text,
let locationDescription = descriptionTextView.text else {
nameRequiredLabel.isHidden = false
heightRequiredLabel.isHidden = false
descriptionRequiredLabel.isHidden = false
print("User did not put in all the required information.")
return
}
The code below it in the IBAction is irrelevant since this is a guard let problem. It won't trigger even when I literally set the values to nil. In my viewDidLoad I put:
nameTextField.text = nil
estimatedHeightTextField.text = nil
descriptionTextView.text = nil
And when I press the button, without changing the values of these texts, the guard let statement still doesn't trigger, and the rest of the function below executes. Any ideas why? Thanks.
