App rejected due to missing usage descriptions (Xcode8)

I had the same issue, and it appears that if any framework you link against has code that asks this permission (even if your app never requests them), the usage descriptions are necessary. But according to my test, if you don't request them, they won't appear in the permissions list of your app.

You can add in your info.plist like :

<key>NSCalendarsUsageDescription</key>
    <string>Explain the reasons for accessing...</string>
    <key>NSPhotoLibraryUsageDescription</key>
    <string>Explain the reasons for accessing...</string>
    <key>NSBluetoothPeripheralUsageDescription</key>
    <string>Explain the reasons for accessing...</string>

etc.

Hope will help someone...

iOS 10 must add permission in info.plist just review this BLOG :- settings-in-ios-10 you get all idea.

Add permission in info.plist file base on your error log.

Note: Write proper reason for permission in string value otherwise apple reject app again.

The descriptions are mandatory for any content you or any frameworks you link against attempt to access. The errors are generated upon an attempt to access the content if a usage description was not supplied, so if you're getting those errors your app must be requesting them. You should discover why your app or its frameworks require these and add appropriate usage descriptions to your app's info.plist.

Or more ideally, if you don't need access, see if there's a way to not request it (or use frameworks that do unnecessarily).
