Sensorkit

SensorKit is Apple's research-grade data collection framework, and this skill covers the whole setup: getting the special entitlement, configuring Info.plist keys, requesting authorization through the Research Sensor & Usage Data sheet, and actually fetching samples. It's restricted to Apple-approved studies only, so you'll need to submit a proposal and wait for the com.apple.developer.sensorkit.reader.allow entitlement before any of this works. The 24-hour data hold means users can delete recordings before your app sees them, which is a big deal for research ethics. If you're building a health study app and need accelerometer data beyond CoreMotion or want keyboard metrics and device usage patterns, this is your only route. Just know it's not for commercial apps.
