How to open native mail in osx app

To open the native Mail app in macOS from your app, you can use the following methods:

Method 1: Using the open command

You can use the open command in your app to open the Mail app. The syntax is:

open -a Mail

This will open the Mail app and create a new window.

Method 2: Using the NSWorkspace class

You can use the NSWorkspace class to open the Mail app programmatically. Here's an example:

import AppKit

let workspace = NSWorkspace.shared
workspace.open([URL(fileURLWithPath: "/Applications/Mail.app")])

This will open the Mail app and create a new window.

Method 3: Using the NSWorkspace class with a URL

You can also use the NSWorkspace class to open the Mail app with a specific URL. For example, to open the Mail app with a new email composed to a specific address:

import AppKit

let workspace = NSWorkspace.shared
let url = URL(string: "mailto:[email protected]")!
workspace.open([url])

This will open the Mail app with a new email composed to the specified address.

Method 4: Using the LSOpenFromURLs function

You can use the LSOpenFromURLs function to open the Mail app with a specific URL. For example:

#include <LaunchServices/LaunchServices.h>

CFArrayRef urls = CFArrayCreate(NULL, (const void **)&url, 1, NULL);
LSOpenFromURLs(urls, NULL);
CFRelease(urls);

This will open the Mail app with a new email composed to the specified address.

Note that these methods require the Mail app to be installed and configured on the user's system. If the Mail app is not installed or is not configured, these methods will not work.
