What is the correct naming for iOS & iPadOS apps when you are implementing AlternateIcons ?

In addition, do you need to delete assets catalogue when you offer alternate icons?

I have seen that it is enough to have 2x and 3x icons but what about settings and notifications?

Here is my file list and Info.plist section.

Code Block plist<key>CFBundleIcons</key>
<dict>
		<key>CFBundleAlternateIcons</key>
		<dict>
				<key>dark</key>
				<dict>
						<key>UIPrerenderedIcon</key>
						<false/>
						<key>CFBundleIconFiles</key>
						<array>
								<string>dark</string>
						</array>
				</dict>
				<key>original</key>
				<dict>
						<key>UIPrerenderedIcon</key>
						<false/>
						<key>CFBundleIconFiles</key>
						<array>
								<string>original</string>
						</array>
				</dict>
		</dict>
		<key>CFBundlePrimaryIcon</key>
		<dict>
				<key>UIPrerenderedIcon</key>
				<false/>
				<key>CFBundleIconFiles</key>
				<array>
						<string>original</string>
				</array>
		</dict>
</dict>
<key>CFBundleIcons~ipad</key>
<dict>
		<key>CFBundleAlternateIcons</key>
		<dict>

						<false/>

						<array>

						</array>
				</dict>
				<key>original</key>
				<dict>
						<key>UIPrerenderedIcon</key>
						<false/>
						<key>CFBundleIconFiles</key>
						<array>
								<string>original</string>
						</array>
				</dict>
		</dict>
		<key>CFBundlePrimaryIcon</key>
		<dict>
				<key>UIPrerenderedIcon</key>
				<false/>
				<key>CFBundleIconFiles</key>
				<array>
						<string>original</string>
				</array>
		</dict>
</dict>

Alternate icons cannot be in the asset catalog, they must be added directly to the app bundle. Here's a gist with an extract from an Info.plist I used in one of my own apps. I provided icons for both iPhone and iPad.
