It appears Apple is sticking to its traditional schedule of releasing iOS beta updates every two weeks with the release of the fourth developer beta of.
In previous iOS release cycles, Apple has typically released an update every two weeks with bug improvements, new features, and enhancements leading up to the eventual official release in September.
Developers can download the update over the air, or through Apple's developer portal.
Apple first announced iOS 13 and iPadOS during WWDC in early June, giving the iPad its own operating system for the first time. The new OS adds better multitasking features, a desktop-class Safari experience, and it even adds support for connecting a mouse to the tablet.
Both the iPhone and iPad also gain a dedicated dark mode, a revamped Mail app, improvements to Messages, as well as performance improvements.
