Apple has recently seen fit to release the final builds of iOS 15.5 and iPadOS 15.5 to the general public. The latest update could be the last update that Apple will release for iOS 15 before it seeds iOS 16 to developers next month. WWDC is scheduled to take place on June 6 where the company will announce its forthcoming updates for the iPhone, iPad, Mac, Apple Watch, and more. While the developer beta for iOS 16 will release shortly after the event, public beta testers would have to wait for a few weeks. It has been suggested by a prominent analyst that the first iOS 16 public beta will be available in July.

According to Mark Gurman from Bloomberg, Apple will release the first public beta of iOS 16 in July. The first public beta will coincide with the third developer beta. Typically, Apple releases the first public beta of iOS when it seeds the second developer beta. Henceforth, if the news has any heft to it, we can presume that the first public beta of iOS 16 will arrive a few weeks later than usual.
