Jak se zdá, vývojáři Applu se neflákají. V pondělí jsme tu měli příchod třetí bety nadcházejících operačních systémů iOS 11.1, watchOS 4.1 či tvOS 11.1 a dnes tu máme verzi další. Je to zhruba hodina, co Apple vydal již čtvrtou vývojářskou verzi, tentokrát však jen pro iOS a watchOS. Verze pro tvOS by mohla dorazit později.

Stejně jako vždy není takto krátce po vydání jasné, co nového Apple do tohoto vydání připravil. Dá se očekávat, že budou opraveny nějaké bugy a přidána nějaká ta funkce. Jakmile se na webu objeví informace o tom, co je v této čtvrté betě nového, budeme vás o tom informovat. Pokud máte vývojářský účet a nainstalovaný aktuální beta profil, můžete si čtvrtou betu stáhnout klasickou OTA metodou. Níže se můžete podívat na oficiální changelog (v angličtině).

Notes and Known Issues

ARKit

Known Issues

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

Audio

Resolved Issues

  • Fixed an occasionally occurring issue with audio latency or distortion on iPad Pro (12.9- inch) (2nd generation) and iPad Pro (10.5-inch). (33844393)

AVFoundation

Resolved Issues

  • Still capture requests using the 720p30 video format with the depthDataDeliveryEnabled property of AVCapturePhotoSettings set to true now works correctly. (32060882)
  • Depthvaluesinthenondefault160x120and160x90depthdataformatsnowreturnthe correct values. (32363942)

Known 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.

Certificates

Resolved Issues

EventKit

Known Issues

  • Initializing an EKCalendarChooser from EventKit can result in an app crash. (34608102)

Foundation

Resolved Issues

  • Clients of NSURLSessionStreamTask that use a non-secure connection fail to connect when an error occurs during PAC file evaluation and the system is configured for either Web Proxy Auto Discovery (WPAD) or Proxy Automatic Configuration (PAC). A PAC evaluation failure can occur when the PAC file contains invalid JavaScript or the HTTP host serving the PAC file is unreachable. (33609198)
