New Messages app: The Messages app now offers the ability to communicate with just a swipe. Tap to Talk feature allows users to share their voice and the same gesture also works for sharing videos and photos within Messages app. Users can choose to share their current location from within Messages.
Predictive text & support for third party keyboards: Apple has also introduced predictive typing for its QuickType keyboard, which is more personalised, and takes context into account, such as who the recipient is and in which app users are typing. The OS now also supports third party keyboards just like Android.
Family Sharing: Family Sharing allows users to communicate and share purchases, photos and calendars within the same household. Family members can browse and download each other’s iTunes, iBooks or App Store purchases. Up to six members can participate, each with their own Apple ID.
Continuity: With iOS 8 and OS X Yosemite, Apple has made switching between iOS and Mac devices more seamless for users who use both platforms. iPhone owners can answer phone calls on their Mac or iPad, and even send SMS messages from any of them. They can start writing an email on one device and seamlessly continue on another.
iCloud Drive: With iCloud Drive, documents of any type can be stored, accessed and edited across devices. Users can make edits on one device and the most up-to-date version of the documents will be available across all devices, including on iOS devices, Macs, Windows PCs or on icloud.com.
Improved Spotlight search: Spotlight has now become intelligent and gives users suggestions from Wikipedia entries, places nearby, trending news, iTunes Store and App Store, among others. It detects context and location to improve search results. It even works inside Safari browser.
