News: iOS 12 Beta 6 for iPhones Released to Apple Developers

iOS 12 Beta 6 for iPhones Released to Apple Developers

For the second time in a row, Apple pushed out a new iOS 12 developer beta on a Monday, and for the first time this round, they've done it only one week after the last one. While the August 6 release of iOS 12 developer beta 6 doesn't contain a wealth of updates, there are still a few things you'll want to know about.

Overall, the iOS 12 dev beta 6 doesn't seem to include anything huge, just minor bug fixes and security patches. However, Apple did remove the iOS "waves" wallpaper from the mix, then added three new colored wallpapers to the Home app. The Music app has a new splash screen promoting music video features, and AirPlay has a tweaked icon on the lock screen.

Dev beta 6 also solves some Bluetooth issues, as well as some Siri-related ones. See the full release notes below to see exactly what those resolves are. But stay tuned for more, though, as we will update this article with any new information we find as we dive into the software ourselves.

To update your iPhone to iOS 12 dev beta 6, you need to be a registered developer with a valid configuration profile. If you have iOS 12's new "Automatic Updates" enabled, you can let the software update overnight. To download the new beta right now, however, open the Settings app, tap "General," then "Software Update." Select "Download and Install," then follow the on-screen prompts to download and install iOS 12 dev beta 6.

While this update was for developers only, public beta testers received the same exact update as "iOS 12 public beta 5" later on the same day, which is quicker than in prior iOS 12 public beta releases; Public beta 4 came just one day after dev beta 5.

All the release notes below apply to both the iOS 12 dev beta 6 and public beta 5.

Resolved Issues

The following is a list of issue fixed in dev beta 6, according to Apple's release notes:
