To delete components, use the same procedure as with deploying components, but also include a delete manifest file that’s named destructiveChanges.xml and list the components to delete in this manifest. The format of this manifest is the same as package.xml except that wildcards aren’t supported.

To deploy the destructive changes, you must also have a package.xml file that lists no components to deploy, includes the API version, and is in the same directory as destructiveChanges.xml

The following sample destructiveChanges.xml file names a single custom object to be deleted:
<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">;
<types>
<members>MyCustomObject__c</members>
<name>CustomObject</name>
</types>
</Package>
+
package.xml
<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">;
<version>56.0</version>
</Package>...
