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

Use the Info tab of the app target editor to set up your document types and exported UTIs. It will set up the Info.plist properly. — matt, Aug 19 '15 at 04:07
Is there anything missing in the plist? So that i could add it in the way you mentioned @matt — Mohammed Janish, Aug 19 '15 at 04:19

Unfortunately, no changes yet @Shebin – Mohammed Janish Aug 19 '15 at 04:19
What does the really contains? Should it be the Bundle ID + file extension? – Mohammed Janish Aug 19 '15 at 07:14
It really works.. I would like to know one more thing. How can I handle this file? – Mohammed Janish Aug 19 '15 at 07:22
I want to open this in one of my veiwcontrollers. – Mohammed Janish Aug 19 '15 at 07:25
As you mentioned in ur question. that delegate will invoke.. the parameter url contain ur file (path) – Shebin Koshy Aug 19 '15 at 07:27
It is an encrypted document. – Mohammed Janish Aug 19 '15 at 07:31
@MohammedJanish you know how to present details from a file that already in ur phone local document directory? – Shebin Koshy Aug 19 '15 at 07:54
@MohammedJanish if yes, then u just convert the url to normal path by Url.path! – Shebin Koshy Aug 19 '15 at 08:35
Of course, But how can i take the obtained url from AppDelegate to my view controller?. @Shebin – Mohammed Janish Aug 19 '15 at 08:42
@MohammedJanish is that viewController is ur first page? u use navigation bar or tab bar? – Shebin Koshy Aug 19 '15 at 08:43
Not the first one. I use navigation controller – Mohammed Janish Aug 19 '15 at 08:44
@MohammedJanish ok..good.. u have to create "var detail :DateToBePassedToThisViewController?" //appdelegate – Shebin Koshy Aug 19 '15 at 09:02
"detail?.functionCallFromAppDelegate(Url.path!)"//paste in that delegate(method) in ur question – Shebin Koshy Aug 19 '15 at 09:03
in the page u use to display " extension DateToBePassedToThisViewController { func functionCallFromAppDelegate (filePath: NSString) { NSLog("path %@", filePath) //here u do ur stuff } }" – Shebin Koshy Aug 19 '15 at 09:05
I got another way. I just declared a global variable to store the path, and it's working fine. I was struggling on this issue and now it's fine. Ur help is really appreciated. – Mohammed Janish Aug 19 '15 at 09:52
