The following features are added in iOS 9 :
* Intelligent search : It is an excellent mechanism to learn user habits and act on that information—open apps before we need them, make recommendations on places we might like, and guide us through our daily lives to make sure we’re where we need to be at the right time.
* Siri : It is a personal assistant to the users that is able to create contextual reminders and search through photos and videos in new ways. Swiping right from the home screen brings up a new screen that houses ‘Siri Suggestions,’ putting favorite contacts and apps right on our fingertips, along with nearby restaurant and location information and important news.
* Deeper search capabilities : It can show results such as sports scores, videos, and content from third-party apps, and we can even do simple conversions and calculations using the search tools on our iPhone or iPad.
* Performance improvements : The following built-in apps have been improved:
* Notes including new checklists and sketching features
* Maps now offering transit directions
* Mail allowing for file attachments
* New ‘News’ app that learns our interests and delivers relevant content we might like to read
* Apple Pay being improved with the addition of store credit cards and loyalty cards
* ‘Passbook’ being renamed to ‘Wallet’ in iOS 9
* San Francisco font
* Wireless CarPlay support
* Optional iCloud Drive app: It is a built-in two-factor authentication system with optional longer passwords for better security.
