I am very new to coding, therefore sorry if this question is really silly) I am making a program which will get users input through text field, multiply it by 2 and then return user the result. I need to check if user typed in the UItextField a number pr if he/she typed in some text. if it's a text then in a UILabel will appear " sorry, give me a number" if it's a number - program will multiply it and show result in a label.

So, how can I check if the users input in UITextField is numeric? I tried casting it to an Int but obviously I can't do magic outside Hogwarts and it didn't work(

Thank you very much!

Please add the code you have, trying to converting the text to an Int is one way to check if the text is numeric. – Joakim Danielson Aug 27 '21 at 16:44
