I am trying to make my in app content searchable with help of Core Spotlight. Everything works great, title and description comes but without thumbnail.
here is what I am trying:
CSSearchableItemAttributeSet *attributeSet = [[CSSearchableItemAttributeSet alloc]initWithItemContentType:(NSString *)kUTTypeImage];
attributeSet.title = @"My First Spotlight Search";
attributeSet.contentDescription = @"This is my first spotlight Search";
attributeSet.keywords = [NSArray arrayWithObjects:@"Hello", @"Welcome",@"Spotlight", nil];
UIImage *image = [UIImage imageNamed:@"searchIcon.png"];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)];
attributeSet.thumbnailData = imageData;
CSSearchableItem *item = [[CSSearchableItem alloc]initWithUniqueIdentifier:@"com.deeplink" domainIdentifier:@"spotlight.sample" attributeSet:attributeSet];
[[CSSearchableIndex defaultSearchableIndex] indexSearchableItems:@[item] completionHandler: ^(NSError * __nullable error) {
if (!error)
NSLog(@"Search item indexed");
}];
