hi, I’m trying to make a sign in and up screen for most of my apps and i want the email domain to be specific. the thing is i don’t know is how to check weather the users entered email contains this domain or not. i tried a few thing but till now none worked. if any screenshot is needed to solve my problem then do ask 
You would need to check if the text input’s text contains “@domain” during the sign up process.
Yes, please post a screenshot of what you’ve tried.
