Shortly after the beta 9 developers (cf. Beta 9 of iOS 12 developers available for download), Apple released the 7th public beta of iOS 12 for download.
This beta is identical to the developer version in terms of new features and improvements. No changelog accompanies it, which means that there are no major additions to report at the moment.
To install it on your iPhone, iPad or iPod touch, you will have to go through the beta.apple.com site and register if you have not already done so in order to retrieve the beta installation profile. Note that the final version of iOS 12 is fast approaching; she should be released next month.
