Email on iOS is not correct

[mattleibow]

Description

Sending an email on a device that does not have an email account set up fails. On my device, I am using Outlook and not the default mail client.

This means that MFMailComposeViewController.CanSendMail will return false. But in actual fact, this is not what I am expecting as a developer. We need to review the logic that determines whether or not an email can be sent.

Expected Behavior

The default email client opens - if this is something that exists on iOS.

Actual Behavior

Throws a FeatureNotSupportedException exception if I am not logged into the mail app.

I am thinking maybe other apps implement:

let email = "foo@bar.com"
if let url = URL(string: "mailto:\(email)") {
    UIApplication.shared.open(url)
}

Flow would be...

• 1 see if we can send mail in mail app... if so awesome
• Else see if mailto: works for uri
• else exception
