When updating and reloading, or scrolling, a UITableView with data from multiple HKQueries of different HKSampleTypes some rows are non-destructively overwritten (i.e. data combined) and the Xcode debug console shows a message [UIWorkIntervalTiming] workIntervalStart: startTimestamp > targetTimestamp; rolling forward by 0.033336
I can find no documentation relating to UIWorkIntervalTiming, in Apple documantation or the wider Web. Has anyone come across this message and under what circumstances?
