Adding file icon to custom file type in Xcode

I'm trying to add an icon (a PNG named "FileIcon") to a custom file type in Xcode 13, but can't seem to actually add it via the interface in Xcode:

Any other way to do this?

Solution

  • Per Apple's article Setting Up a Document Browser App, there is a snippet in there for the plist:

    <key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array/>
        <key>CFBundleTypeName</key>
        <string>Text</string>
        <key>LSHandlerRank</key>
        <string>Alternate</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>public.data</string>
        </array>
    </dict>
</array>

    Is this set up correctly in your plist?
