i would like to know how to calculate SHA1 fingerprint in ios swift, i am trying to calculate it on runtime to have some potential checking of integrity of my application. I know macos has some direct APIs to get it but i dont know how can we achieve this in iOS as well. P.S. I am new to iOS development , so please bear with me if i ask some naive questions in this thread.

Is there a way to check your app signature to verify if any one has tampered with the ipa file. I want to know specifically how to determine and handle this type of situation. How can i do a check for this in code(swift).
