Dopo il rilascio la scorsa settimana della versione definitiva di iOS 11 e ieri di iOS 10.1, Apple ha reso disponibile agli sviluppatori anche la prima versione preliminare di iOS 11.1. Come conferma il change-log ufficiale, che riportiamo di seguito, iOS 11.1 risolve alcuni dei bug emersi in questi giorni.
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
