Apple's iOS 10 Lets Users Uninstall Some Preloaded Apps

— -- It's something Apple didn't mention during the jam-packed Worldwide Developers Conference in San Francisco.

Starting with iOS 10, which is set to be released this fall, iPhone and iPad users will be able to delete some of the preloaded apps on their devices, according to a support document posted on Apple's website.

"For people who appreciate a tidy screen or are sick of looking at apps they don't use, getting rid of unused Apple apps, such as Calculator, Compass, Stocks or the Apple Watch app may be welcome news, however it's worth noting the 23 apps are designed to be very space efficient, so all of them together use less than 150MB," according to Apple.

iOS 10

Expect other big changes from iOS 10, which Apple debuted during a keynote address on Monday.

Perhaps the most notable change is coming to iMessages, which are being injected with more utility and creativity. The new iOS is so smart it can highlight "emojifiable" words, giving users a heads up if they would like to change the word "pizza" to an image of a slice or find the perfect emoji face to express the word "love." Among the other options: add handwritten messages and special flair or even take over the entire screen with a note. Invisible ink also provides a dramatic reveal for surprise messages and photos.

Apple is opening iMessages to developers, allowing them to create more experiences for the platform, such as sending money to a friend.

The other radical change: developers will get a chance to tweak Siri's capabilities. This will allow even more utility for the virtual assistant, allowing Siri to work within apps to help with a command, such as transcribing a message to a friend within an app.

Siri will also bring more value to QuickType by suggesting more intelligent responses in messages based on what it knows you're doing, where you are, what's on your calendar or what you've been searching for.

Apple is also bringing more organization to photos by using deep learning to recognize people, places and scenes in a photo collection, making searching for a memory that much easier. The process is done locally on a device and maintains a user's privacy, according to Apple.

The new iOS can also transcribe all of those voicemails you never listen and will bring a more proactive approach to Maps. Also expect new options in Apple News and a cleaner user experience for Apple Music — which was launched at last year's WWDC.
