The first thing I'd check is whether samples are being classified at recording time. The item.activityType
getter relies on either cached classifierResults
or on the classifiedType
of each sample within the item. So if you haven't explicitly touched item.classifierResults
to trigger full classifier results for the item, then item.activityType
won't do so either, and will fall back to modeMovingActivityType
/ modeActivityType
. Those two rely on the individual samples already having been classified, typically at time of recording.
As long as the TimelineRecorder
was initialised with a classifier, eg let recorder = TimelineRecorder(store: store, classifier: UserTimelineClassifier.highlander)
, and the device has an internet connection and valid LocoKit API key, the recorder will be classifying each sample at recording time.
Though item.classifierResults
also relies on the recorder having a valid classifier assigned, so that would be the second thing to check: whether you get sensible results by going direct to item.classifierResults
.
It'd also be worth printing the sample.classifiedType
of each sample within the item. eg for sample in path.samples { print("sample.classifiedType: \(sample.classifiedType)") }
. The results of that should give better insight into what's going on with modeMovingActivityType
/ modeActivityType
.
Let me know you get on!

@sobri909 .. actually I'm not using classifier
lazy var recorder :TimelineRecorder = {
let recorder = TimelineRecorder(store: store)
return recorder
} ()

Ah, without a classifier, samples and items won't have a activity types. That'll be the problem 😉
