Wood,

Just trying to summarize the steps for uploading images:

Step 1: Define the class :

    class Image : NSObject {    //all NSObjects in Kinvey implicitly implement KCSPersistable
        var entityId: String! //Kinvey entity _id
        var image: UIImage!
    }

Step 2: Override the hostToKinveyPropertyMapping & kinveyPropertyToCollectionMapping method:
   
        override func hostToKinveyPropertyMapping() -> [NSObject : AnyObject]! {
            return [
                "entityId" : KCSEntityKeyId, //the required _id field
                "image" : "image"
            ]
        }
       
        override class func kinveyPropertyToCollectionMapping() -> [NSObject : AnyObject]! {
           
            return [
                "image" : KCSFileStoreCollectionName
            ]
        }
   
Step 3: Initialize store object with KCSLinkedAppDataStore object.

        var collection = KCSCollection(fromString: "Images", ofClass:Image.self)
       
        var imageToSend = KCSLinkedAppdataStore.storeWithOptions([
            KCSStoreKeyResource : collection,
            KCSStoreKeyCachePolicy : KCSCachePolicy.Both.rawValue,
            KCSStoreKeyOfflineUpdateEnabled : true
            ])

Step 4: Upload the Object as follows:

        let imageSendingData = Image()
        imageSendingData.image = UIImage(data: UIImageJPEGRepresentation(image, 0.5)!)
       
        imageToSend.saveObject(imageSendingData, withCompletionBlock: { (objectsOrNil, errorOrNil) -> Void in
            if errorOrNil != nil {
                print("Error saving image: \(errorOrNil)")
            } else {
                print("Save image successful")
            }
        }, withProgressBlock: nil)

In the Console, you should see a new entry created in that collection (with image column storing the _KinveyRef and the newly uploaded file should appear under “Console->Data->Files (Select Files instead of a collection)”).

Thanks,

Pranav
