If you submitted your app to iTunes store or plan to submit, you might be getting this notice
This app attempts to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSCalendarsUsageDescription key with a string value explaining to the user how the app uses this data.
This issue is related with admob, based on our test with your test app submission. But other SDK can also potentially have this issue.
To solve this issue you need to add the following to your Info.plist
<key>NSCalendarsUsageDescription</key>
<string>Advertisement would like to create a calendar event.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Advertisement would like to store a photo.</string>
<key>NSBluetoothPeripheralUsageDescription</key>
<string>Advertisement would like to use bluetooth.</string>
We’re working on upgrade the SDKs currently, hopefully it will be resolved soon.
