Apple releases iOS 11.1 to developers

Apple on Wednesday released iOS 11.1 to developers, which appears to include several bug fixes and enhancements. The new software arrives just a day after Apple introduced iOS 11.0.1 to consumers.

The release notes for iOS 11.1 highlight a number of known issues and incoming fixes. There’s no mention of the “crackling” noise Apple said is affecting a small number of iPhone 8 users, but expect a fix to be released soon.

Apple released iOS 11 earlier this month, though it was missing some of its biggest features, including Apple Pay Cash and Message in iCloud. Hopefully, iOS 11.1 will be the release that makes those features available—expect the software to line up with the iPhone X’s release in November.

You can read the full release notes down below.

Known Issues

  • ContinuingfromabreakpointwhiledebugginganARSessionmayresultinVIObreaking. Any visual objects placed in the world/anchor are not visible. (31561202)

New Issues

  • When using the TrueDepth front-facing camera on iPhone X, setting the capture device’s activeFormat to a binned video format (see AVCaptureDeviceFormat isVideoBinned) for capture and enabling delivery of camera calibration data causes the resulting AVCameraCalibrationData to contain invalid information for the intrinsicMatrix property.

Note: Configuring a capture session using a session preset never selects binned formats.
