While fetching the contacts list using NSContactsUsageDescription, I am getting the below error.
This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSContactsUsageDescription key with a string value explaining to the user how the app uses this data.
Also it was taking very long time to fetch the entire contact list in swift and in swift 3 there is this error.
