How to use CoreSpotlight categories?

No clarification on this? Wondering the same thing

I tried with CSSearchableItemAttributeSet(itemContentType: kUTTypeMessage as String), but the results returned are just *authorNames* no textContent or recipients were displayed.

As per Apple documentation :

For navigation use @property(copy, nullable) NSNumber*supportsNavigation of CSSearchableItemAttributeSet Class Reference

When an item includes

latitude

and

longitude

properties, these properties can be used for navigation to the location represented by the item. For example, it makes sense to set

supportsNavigation

to

1

for an item that represents review for a specific restaurant, but not for an item that represents a photo of a person.

For phonenumbers use @property(copy, nullable) NSNumber*supportsPhoneCall of CSSearchableItemAttributeSet Class Reference

When an item includes the

phoneNumbers

property, the phone number can be used to initiate phone calls. You can use the

supportsPhoneCall

property to indicate when making a phone call is appropriate and likely to be a primary action for the user. For example, you might set

supportsPhoneCall

to

1

for an item that represents a business, but not for an item that represents an academic paper that lists the phone numbers of the authors or the institution.

@guhan0, I also noticed the addition of supportsNavigation and supportsPhoneCall in a recent beta. However, this still doesn't answer the question which contentType should be used and which of the properties in the various CSSearchableItemAttributeSet categories are actually displayed.

Also, it seems that supportsNavigation and supportsPhoneCall are mutually exclusive.
