Every page in the current release follows the same pattern, so you can build the URL directly instead of fetching an index: a page at /api/swift/<page>/ is at /llms-api-swift/<page>.txt.

assetTrackingData

Declaration

func assetTrackingData(assetId: String? = nil) -> Vps2AssetTrackingData?

Summary

Gets the pose of a VPS asset's origin in the device's AR tracking space.
Polling is the demand that starts tracking: the first call for an asset
begins tracking its origin frame and returns nil while that spins up,
so keep polling. Data is only served while the asset is fully tracked;
nil covers never-localized, limited, and lost tracking alike, and a
nil assetId while the device is not localized. Content should not be
placed while this returns nil.

Returns

The asset's tracking data, or nil while none is available.

Parameters

Name	Type	Summary
assetId	String?	The identifier of the asset, or `nil` for the asset the device is currently localized to (see `Vps2Localization/localizedAsset`).
