Big changes appear to be headed to iOS thanks to iOS 10. First party apps have begun appearing in the App Store, hinting at the strong possibility iOS users will be able to uninstall stock iOS apps. It also could potentially mean that users will be able to install and use third-party apps as default apps.

This could mean that users will be able to use an app like Gmail or Spark as the default email app. It could also mean that the stock Music app could be replaced by an app like Spotify.

Apps that we see thus far are Weather, Watch, Voice Memos, Videos, Tips, Stocks, Reminders, Podcasts, Notes, Music, Maps, Mail, iTunes Store, FaceTime, Contacts, Compass, Calendar, and Calculator.

More details will inevitably be revealed as the rest of the currently ongoing WWDC keynote continues.
