I'm attempting to create a form step where one of the form step items is an email input. For this I want to validate the email against certain domains i.e.
@gmail.com, @icloud.com, @me.com
I can see we have an email answer format in the form of this:
ORKEmailAnswerFormat()
However I can't see anywhere in this type that allows me to apply a validation regex. Looking into this I see we have the following
ORKAnswerFormat.textAnswerFormatWithValidationRegex(validationRegex, invalidMessage)
I suppose this is my best option? If so, would anyone know of a regex (my regex isn't the greatest!) in swift that would handle the 3 domains stated above?
I have something like this...(not the greatest i know!)
[A-Z0-9a-z._%+-][email protected]
[A-Z0-9a-z._%+-]+@(?:icloud|me|gmail)\.com
(or, if you don't care about capturing:)
[A-Z0-9a-z._%+-]+@(icloud|me|gmail)\.com
Now I made two modifications. I escaped the . and I made it so that the other two domains are options.
I suggest that you convert the whole thing to lower case. I don't know Swift, but you may be able to use one of its functions or the i modifier:
(?i)[0-9a-z._%+-]+@(icloud|me|gmail)\.com
