3. Dealing With Email Composing Results

To handle the email composing results, provide a closure as argument to the result optional parameter. The closure's argument is a Result<EmailComposerResult, Error> value. See the discussion about the EmailComposerResult symbol for more information about the possible values on success.

Here is an example of determining the result:

Button("Send email") {
    showEmailComposer = true
}
.emailComposer(isPresented: $showEmailComposer) { result in
    switch result {
        case .success(let value):
            if value == .deviceCannotSendEmails {
                print("Device cannot send emails.")
            }
            print(value.description)
        
        case .failure(let error):
            print(error.localizedDescription)
    }
}

The EmailComposerResult/deviceCannotSendEmails value is treated separately above in order to highlight that the case of a device unable to send emails is among all possible cases of a successful result. The other cases are: sent, saved, cancelled, and failed. For each one there is a textual description provided.
