I have an app on the App Store for many years enabling users to post text into clouds in augmented reality. Yet last week abruptly upon installing the app on the iPhone the screen started going totally dark and a list of little comprehensible logs came up of the kind:
ARSCNCompositor <0x300ad0e00>: ARSCNCompositor (0, 0) initialization failed. Matting is not set up properly.
many times, then
RWorldTrackingTechnique <0x106235180>: Unable to update pose [PredictorFailure] for timestamp 870.392108
ARWorldTrackingTechnique <0x106235180>: Unable to predict pose [1] for timestamp 870.392108
again several times and then:
ARWorldTrackingTechnique <0x106235180>: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop]. Failed on timestamp: 870.413247, Last known timestamp: 865.350198, Delta: 5.063049, System timestamp: 870.415781, Delta between system and frame: 0.002534. }
and then again the pose issues several times.
I hoped the new beta version would have solved the issue, but it was not the case. Unfortunately I do not know if that depends on the beta version or some other issue, given the app may be not installed on the Mac simulator.
