How to use

Getting the list of supported clients

let clients = ThirdPartyMailClient.clients

Testing the client availability (i.e. if the app is installed)

⚠️ In order to test the client availability, your app needs to declare the relevant URL scheme in its Info.plist file, by adding a LSApplicationQueriesSchemes array. You can find an example here, or check out the documentation.

if ThirdPartyMailer.isMailClientAvailable(client) {
    // ...
}

Opening the client (with optional message recipient, subject, body, cc, and bcc)

ThirdPartyMailer.openCompose(client, recipient: "[email protected]")

ThirdPartyMailer.openCompose(client, recipient: "[email protected]", subject: "Hello", body: "Good morning…", cc: "[email protected]", bcc: "[email protected]")

🆕 Using the system default mail client

If you don’t specify a client, the openCompose(…) function will use .systemDefault, a client defined for the standard mailto: scheme. By default, it will open Apple Mail, but if the user has selected a custom mail client (iOS 14), it will automatically open it instead.

ThirdPartyMailer.openCompose(recipient: "[email protected]")
