Comment on Prevent Text Field from containing 2 decimal points in Swift

Note that your code should not crash, whatever input user does. You have to make it more robust. May be the reason is you are converting to Float, something like      let value = Float(textField.text!) If so, you should instead test for nil with:          let value = Float(textField.text!) ?? 0.0

Comment on Who's on top? Swift, nonSwiftUI

No, normally it is the order in the storyboard that matters. If you move Red View higher in list, it will appear below Green. Even if there is no IBOutlet created, just the views in IB.

Comment on [Swift] How to properly subclass UITextfield and work with its delegate

As a precaution you could add information header to the subclass (///) warning that it sets its delegate and this should not be done in calling method. Or use myTF.delegate = myTF

You did it perfectly by marking the correct answer. That "closes" the thread, showing readers that you got what you needed.

Comment on [Swift] How to properly subclass UITextfield and work with its delegate

The key point is that an object can have only one delegate ; so you cannot trigger textFieldDidBeginEditing() in both the calling code as well as the one inside the subclass by invoking the delegate. But notification as I described will allow to get a similar result.

Comment on Does Apple allow an app that has a log-in feature without a sign-up feature on App Store?

Sorry if that was not clear. You never have an obligation for a sign-in. But if you have some sign-in, you must also have Apple sign-in, except for few cases. So, in your case, with a simple login, without any sign-in to Google, Facebook, … you don't need any sign-in.

Comment on Need Help Transfer Data From Button

Note that you cannot have a segue from a button altogether with an IBAction. Segue would be executed directly and IBAction not called (that different from having performSegue in IBAction, because in this case, segue is not from button but from VC generally).
