If history is any guide, the next iOS 9 beta should arrive for developers early next week. The first iOS 9 beta was announced and released on June 8.
In 2014 and 2012, respectively, iOS 8 beta 2 and iOS 6 beta 2 arrived 15 days after the first. In 2013, iOS 7 beta 2 arrived 14 days later. This suggests that Tuesday, June 23 is the most likely day when iOS 9 beta 2 is released to developers.
First introduced during the Worldwide Developers Conference (WWDC) keynote last week, iOS 9 features a number of under the hood changes, including a revised Notes app. A universal News app is also launching with the release, as is multitasking for iPad. Apple’s iOS 9 should arrive for the public this fall alongside the 2015 iPhone lineup.
Non-developers should get their first taste of iOS 9 in July, when the first public beta is released. Most likely, the release will coincide with the unveiling of iOS 9 beta 3 for developers.
On June 30, Apple is expected to release iOS 8.4. This update will include the new Apple Music service, which was also announced at WWDC.
