Your logic is reversed. Once it hits the first if statement it holds true because the e-mail IS missing. You need to reverse your statements to check for both first. You've also set it to check if either e-mail or password is blank. 

if (self.textFieldEmailOutlet.text == "") && (self.textFieldPasswordOutlet.text == ""){
        GenericFunctions.showAlert(title: "Alert", message: "Please enter your email id & password")
    }else if textFieldPasswordOutlet.text == ""{
        GenericFunctions.showAlert(title: "Alert", message: "Please enter your password")
    }else if textFieldEmailOutlet.text == ""{
        GenericFunctions.showAlert(title: "Alert", message: "Please enter your email id")
    }

This checks if the e-mail AND password are missing, and gives the result you were looking for. If either one of them is filled out, however, it will fail the first if clause and check to see if there is a password. If there is a password it will move on to check the e-mail address where it would (logically) fail and send the alert about needing an e-mail address.
