Apple declined to comment ahead of WWDC. Here's what Apple will talk about during its keynote at 10 a.m. PT on Monday. Tune back to CNET for a live blog and full coverage from the event. Apple's mobile operating system gets revamped every year and launches when its newest smartphones hit the market, typically in the fall, but WWDC acts as a preview for iOS. Jony Ive, Apple's head of design, started overseeing the software with iOS 7 in 2013. iOS 8, which Apple revealed at last year's WWDC and launched September 17, added much-desired functionality such as iCloud improvements and third-party app notifications. But it also was hurt by bugs and other problems.

This year's update isn't expected to include drastic changes but instead should refine what Apple iphone screen protector installation has been doing over the past couple of years: making its various devices, including mobile and computers, talk to each other and make everything easier for users, iOS 9 could add support for Apple's Force Touch feature, which mimics feeling the screen respond or click when you push on it -- an illusion created by a small motor generates a small vibration, Some other areas that could see improvements are the keyboard in iOS, and Siri, the company's digital voice assistant..

Google in May showed off updates to its Google New feature, called Now On Tap, that predicts what you want to do such as showing gas stations along your route to the car rental office before you even ask. Apple is expected to respond with its own offering that seeks to provide you with relevant information from your calendar, contacts and other apps. Along with updating its mobile operating system, Apple will show off new features for its computer software, Mac OS X 10.11. The operating system had a big revamp last year with Mac OS X 10.10 Yosemite, making it likely this year's update will largely be a refinement instead of a major overhaul.

Yosemite included features that allow you to "hand off" tasks, That includes letting you start a program -- such as writing an email or composing a text -- on an iPhone and then finish it on an iPad or Mac, Apple could show off other similar actions with the new operating system, and it's also expected to talk up the security features of its software, Apple hasn't done much with Beats since buying the headphone maker and streaming music provider for $3 billion last year, That's about to change, Apple likely will introduce a new music service that directly competes with Spotify, allowing users to stream songs instead of buy tracks and albums like in iTunes, It's expected to cost $10 a iphone screen protector installation month and feature celebrity DJs..

Apple revolutionized the music industry by letting consumers buy digital songs through iTunes, but people aren't purchasing music like they used to. That makes it important for the company to offer a streaming service that goes beyond iTunes Radio, Apple's basic streaming radio service that generates revenue from advertising. The new service, which should also be available on Android, likely won't offer a free, ad-based streaming option, though Apple is expected to keep iTunes Radio going. Apple just introduced Apple Watch in April, but it's already working on software updates. Apple at WWDC will detail a developer kit preview that will let app makers write software directly for the smartwatch, Jeff Williams, Apple's senior vice president of operations since mid-2010, said at the Code conference in late May. That will make it easier to create more-powerful, so-called "native" apps that work on the device itself, which should improve the experience for Apple Watch users. It also should allow developers to take advantage of more Apple Watch features.
