Notes and Known Issues

ARKit

Known Issues

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

AVFoundation

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. (34200225)

Workaround: Select an alternate capture format whose isVideoBinned property is false.

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

Resolved Issues

  • Stillcapturerequestsusingthe720p30videoformatwiththe depthDataDeliveryEnabled property of AVCapturePhotoSettings set to true now works correctly. (32060882)
