Apple Seeds Fourth Beta of iOS 10.3 to Developers for Testing

Apple Seeds Fourth Beta of iOS 10.3 to Developers for Testing

Apple on Monday seeded the fourth beta of iOS 10.3 to developers. The new update comes only one week following the third beta release.

Apple Seeds Fourth Beta of iOS 10.3 to Developers for Testing

Registered developers can download the new iOS 10.3 beta – Build 14E5260b – from the Apple Developer Center, or over the air with the correct configuration installed on their device. (If you’re a developer, you know what that means.)

Fixed in this Release

Find My iPhone

Find My iPhone now supports Location and Play Sound for AirPods.

  • Location and Play Sound should now work as expected.
  • Play Sound emits a noise from the AirPods that reaches a high volume after a few seconds. Please remove both AirPods from your ears before testing this feature.

iCloud Analytics

During setup, users should no longer reach the “iCloud Analytics” page if they have not yet signed in.

iCloud Backup

Nightly backups should no longer fail with the error message “Some files were unavailable during the last backup.”

LAN Asset Cache

LAN Asset Cache functionality should now work as expected.

Lightning Video Adapters

Lightning video adapters should now work as expected.

Managed and Shared Devices

  • On managed devices, users should no longer be able to override the current iCloud Document Sync setting.
  • Shared iPad settings should now work as expected.

Xcode Simulator

  • The legacy iCloud button in Settings has been removed. iCloud settings are now available within the new Apple ID settings pane.
  • Scrolling in the Today View should no longer crash.
  • Attempting to enable iCloud Drive through the iCloud Drive app before the user is signed into iCloud should no longer cause Settings to crash.

Notes and Known Issues

Managed and Shared Devices

The ability to update devices from a remote server is in development and may not yet work as expected.


When a third party application invokes openURL: on a tel://, facetime://, or facetime-audio:// URL, iOS displays a prompt and requires user confirmation before dialing.


The new SiriKit car commands are still in development and may not yet work as expected.


SOS is only supported in India.


Safari now supports the prefers-reduced-motion media query. This query allows a web developer to provide alternate page styles for users who are sensitive to large areas of motion. Users can change their preference for reduced motion in the Accessibility section of System Preferences.

The iOS 10.3 update removes support for SHA-1 signed certificates used for Transport Layer Security (TLS) in Safari and WebKit that are issued from a root Certification Authority (CA) included in the operating system default trust store. All other TLS connections will continue to support SHA-1 signed certificates until late 2017. SHA-1 signed root CA certificates, enterprise distributed SHA-1 certificates, and user-installed SHA-1 certificates are not affected by this change.
