Intro

EasySpotlight makes it easy to index contento to CoreSpotlight and handle app launches from Spotlight.

Requirements

CoreSpotlight is only available in iOS 9.0 or later

Installation

EasySpotlight is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "EasySpotlight"

Saving content to Spotlight

To use simply create a struct or class that implements the SpotlightConvertable protocol.

@available(iOS 9.0, *)
// implement to enable indexing methods
public protocol SpotlightConvertable:SpotlightIndexable {
    var title:String? {get}
    var identifier:StringLiteralType {get}

    //optional
    var itemType:String {get}
    var thumbnailImage:UIImage? {get}
    func configure(searchableItem item:CSSearchableItem)
}

Here is a simple example of a struct that implements the protocol and becomes indexable.

struct SimpleStruct:SpotlightConvertable {
    var title:String? = nil
    var identifier:String
}

You can now use all of the following methods:

let x = SimpleStruct(title:"Bob", identifier:"identifier")
EasySpotlight.index(x) { error in 
    handleError(error)
}
EasySpotlight.deIndex(x)
EasySpotlight.deIndexAll(of: SimpleStruct.self)
EasySpotlight.index([x])

If you want to further configure the CSSearchableItem and CSSearchbleAttributeItemSet properties you can implement the configureSeachableItem method in the protocol.

Retrieving content

In order to easily handle when the app is opened via a spotlight search, you must implement the SpotlightRetrievable protocol:

public protocol SpotlightRetrievable:SpotlightConvertable {
    static func item(with identifier: String) -> Self?
}

Now you have to register a handler for that type in application:didFinishLaunchingWithOptions::

EasySpotlight.registerIndexableHandler(SimpleStruct.self) { item in
   // handle when item is opened from spotlight
   assert(item is SimpleStruct)
   print("started with: \(item)")
}

Now all that is left is to implement the function called when the app opens from a spotlight search:

func application(application: UIApplication, continueUserActivity userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> Void) -> Bool {
     return EasySpotlight.handle(activity: userActivity) || handleOtherUserActivities(userActivity)
}

Usage

See the included example application for a sample that indexes and retrieves objects from Realm.
