Verify that Xcode is coming from a regular channel

Because of the recent Xcode Ghost event, it is necessary to verify that it comes from a formal channel when Xcode is installed.

Run the following command on the terminal system to enable detection:

Spctl--assess--verbose/applications/xcode.app

Enter Finish press ENTER, then wait for verification, about a few minutes or so.

Then return the validation result information:

The first type:

/applications/xcode.app:accepted

Source=mac App Store

The second type:

/applications/xcode.app:accepted

Source=apple

The third type:

/applications/xcode.app:accepted

Source=apple System

All three of these show that Xcode is from a formal channel, otherwise it is informal channel, there may be tampered with the content of the situation.
