How to associate CSV file to my app in iOS 7

Question

Good day, everyone.

I followed these two tutorials line by line, try to associate my app to the csv file (email app attachment), but I after I added these down below changes to my app's plist file, then build my app and run it my device (iPhone 4, iOS 7.0.4), nothing happens, I mean when I clicked on the .csv file in the email, my app still does not show up in the open-in available application list, I just don't know where I did wrong, or iOS 7 has different way doing this?

this is what my plist changes (the new entries added followed by the tutorial) looks like:

here's the app setting screen:

and here's the xml version:

You're missing the UTI type in your CFBundleDocumentTypes definition:

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeName</key>
        <string>CSV Document</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSItemContentTypes</key>
        <array>
            <string></string>
        </array>
    </dict>
</array>

should be:

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeName</key>
        <string>CSV Document</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>Damian-s.${PRODUCT_NAME:rfc1034identifier}</string>
        </array>
    </dict>
</array>

I tried this on iOS 12 and is working fine. But not working with iOS 13. The app does not appear in the list shown on tapping "Share File via...". Am I missing anything? – Daedal
