Apple makes fourth iOS 13.1 developer build available for iPhone 11, Pro models

At the same time as releasing iOS 13 to the public, Apple has made the fourth developer beta of iOS 13.1 available to trial participants using an iPhone 11, iPhone 11 Pro, or an iPhone 11 Pro Max.

Apple released the fourth beta build of iOS 13.1 for developer testing on Wednesday, alongside the fourth build of iPadOS 13.1 and the 11th beta of tvOS 13. That release was for currently-available iPhones and not the new models.

With today's beta update, Apple is making the same builds available to use on the 2019 iPhone models: The iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max.

Both iOS 13.1 and iPadOS 13 are anticipated for release on September 24, six days earlier than originally announced.

Both AppleInsider and Apple strongly suggest users avoid installing betas on to "mission-critical" or primary devices, due to the potential for data loss or other issues. Instead, the recommendation is to install betas onto secondary or non-essential devices, and to ensure there are sufficient backups of important data before making any major changes.
