My iPad 2 has iOS 9.3.2 but still Core Spotlight
doesn't work.
Want to know whether it is supported or not?
As per the Apple documentation :
NOTE
Although app search is available in iOS 9 and later, the search functionality of NSUserActivity and Core Spotlight is not supported on iPhone 4s, iPad 2, iPad (3rd generation), iPad mini, and iPod touch (5th generation).
