associate file types with iOS application in swift

Question

I am new to iOS development. I designed a custom attachment to send through mail. When I receive the attachment in mail, I want to open the attachment in my app. Here is my info.plist

<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.data</string>
        </array>
        <key>UTTypeDescription</key>
        <string>pvt file</string>
        <key>UTTypeIdentifier</key>
        <string>com.pryvateBeta.crypt.pvt</string>
        <key>UTTypeTagSpecification</key>
        <dict>
            <key>public.filename-extension</key>
            <string>pvt</string>
        </dict>
    </dict>
</array>
<key>CFBundleDocumentsType</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array/>
        <key>CFBundleTypeName</key>
        <string>pvt file</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.pryvateBeta.crypt.pvt</string>
        </array>
    </dict>
</array>

And here is my Appdelegate

func application(application: UIApplication, openURL Url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    let encrypteddata = NSData(contentsOfURL: Url)
    

    return true
}

I have asked the question before in this LINK. It was a possible duplicate of this QUESTION. But, I didn't get the solution and could not find where the problem is.

What is missing in my code? Any help is appreciated
