Just get the first element from the array?

self.Email = self.EmailArray.first!

(this is the same as self.Email = self.EmailArray[0])

NB: first! or [0] will both crash if the array is empty. The original question uses as! so obviously just need this to work. However, if you wanted safety you would use something like

if let email as self.EmailArray.first {
    self.Email = email
}

or

self.Email = self.EmailArray.first ?? "no email found"
