Firebase FireAuthErrorCode when email address is empty - swift

Question

I'm implementing FireAuth error codes for firebase email and password signup, they all work except in 2 cases. When the email address field is empty, case .errorCodeInvalidEmail is called. When i type some letters (no valid email address), the default case is called. For the password field, it's the other way around. When i type one character the case .ErrorCodeWeakPassword" is called. When i leave the field empty, i go to the default case.
this is my code:
#IBAction func SignInButtonPressed(_ sender: LogInVcButton) {
if let email = emailField.text, let password = pwdField.text {
FIRAuth.auth()?.signIn(withEmail: email, password: password, completion: { (user, error) in
if error == nil {
print("Email User Authenticated with Firebase")
} else {
FIRAuth.auth()?.createUser(withEmail: email, password: password, completion: { (user, error) in
if error != nil {
if let errCode = FIRAuthErrorCode(rawValue: (error?._code)!) {
switch errCode {
case .errorCodeEmailAlreadyInUse: self.errorMessage(message: "Email address is already in use")
case .errorCodeInvalidEmail: self.errorMessage(message: "Email address is invalid")
case .errorCodeWrongPassword: self.errorMessage(message: "Wrong password")
case .errorCodeWeakPassword: self.errorMessage(message: "Password needs to be minimum 6 characters")
// TODO: A case for if the password field is blank
default: print("default")
}
} else {
print("Successfully Authenticated with Firebase")
}
}
})
}
})
}
}
I don't see which error code would handle the wrong email format or the empty password field in the docs. I can try to handle them my own, but i would think firebase would cover these cases ? https://firebase.google.com/docs/auth/ios/errors
Anyone can help me out ?
edit: after digging in some deeper i managed to print out the firebase descriptions of the errors.
if i pres sign in with emailAddress and password empty:
Optional(Error Domain=FIRAuthErrorDomain Code=17008 "The email address is badly formatted." UserInfo={NSLocalizedDescription=The email address is badly formatted., error_name=ERROR_INVALID_EMAIL})
case .errorCodeInvalidEmail is called. this is ok
When i write an invalid email address and empty password empty i get:
Optional(Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information." UserInfo={NSUnderlyingError=0x6080000565c0 Domain=FIRAuthInternalErrorDomain Code=3 "(null)" UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey={
code = 400;
errors = (
{
domain = global;
message = "MISSING_PASSWORD";
reason = invalid;
}
);
message = "MISSING_PASSWORD";
}}}, error_name=ERROR_INTERNAL_ERROR, NSLocalizedDescription=An internal error has occurred, print and inspect the error details for more information.})
NOK .errorCodeInternalError: It says missing password, but it should check the email address
When i type an invalid email address and one character in the password field i get:
Optional(Error Domain=FIRAuthErrorDomain Code=17008 "The email address is badly formatted." UserInfo={NSLocalizedDescription=The email address is badly formatted., error_name=ERROR_INVALID_EMAIL})
This seems ok
when i type a valid email address and no password:
Optional(Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information." UserInfo={NSUnderlyingError=0x6080000565c0 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)" UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey={
code = 400;
errors = (
{
domain = global;
message = "MISSING_PASSWORD";
reason = invalid;
}
);
message = "MISSING_PASSWORD";
}}}, error_name=ERROR_INTERNAL_ERROR, NSLocalizedDescription=An internal error has occurred, print and inspect the error details for more information.})
NOK. .errorCodeInternalError
when i type a valid email address and one character in the pw field
Optional(Error Domain=FIRAuthErrorDomain Code=17026 "The password must be 6 characters long or more." UserInfo={NSLocalizedDescription=The password must be 6 characters long or more., error_name=ERROR_WEAK_PASSWORD, NSLocalizedFailureReason=Password should be at least 6 characters})
.errorCodeWeakPassword is called. This is ok too. and should also be the case on point 5 imo
When i type no email and a valid password
Optional(Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information." UserInfo={NSUnderlyingError=0x600000053ce0 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)" UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey={
code = 400;
errors = (
{
domain = global;
message = "MISSING_EMAIL";
reason = invalid;
}
);
message = "MISSING_EMAIL";
}}}, error_name=ERROR_INTERNAL_ERROR, NSLocalizedDescription=An internal error has occurred, print and inspect the error details for more information.})
NOK Internal Error is called. Why not same as in point 1 ?
