Apple has begun releasing beta versions of watchOS 6.1.1, tvOS 13.3, iPadOS 13.3 and iOS 13.3, which developers can use for app testing purposes.
These builds can be downloaded at the Apple Developer Center by individuals who have signed up for the Developer Beta program or via OTA on beta testing-specific hardware. Public beta versions are usually released shortly after developer versions and are available to download at the Apple Beta Software site.
Both iPadOS 13.2 and iOS 13.2 have HomeKits Secure Video, Siri improvement options, Deep Fusion photography, 70-plus brand new emojis and other changes. Other than that, there’s currently no information on feature additions for the aforementioned software builds.
Beta versions are not recommended for public use as they may still contain bugs and may crash often. Apple says that beta software may cause data loss and other concerns, so use it at your own risk. If possible, only install on non-essential and secondary devices.
