I'm trying to run this demo, which opened a month ago, but now returns 2 issues in xCode: https://developer.apple.com/documentation/visionos/diorama
My goal is to better understand how to use Reality Composer Pro to develop visionOS apps for the Vision Pro.
BillboardSystem.swift:39:58 Value of type 'WorldTrackingProvider' has no member 'queryDeviceAnchor'
Cannot find 'Attachment' in scope. Preview paused shows.
Any thoughts on where I'm off? Thanks!
Hello!
This API was renamed to "queryDeviceAnchor": https://developer.apple.com/documentation/arkit/worldtrackingprovider/4293525-querydeviceanchor?changes=late__8_8
So, the following would be the replacement for the code that isn't compiling:
worldTrackingProvider.queryDeviceAnchor(atTimestamp: CACurrentMediaTime())
Also
let cameraTransform = Transform(matrix: pose.originFromDeviceTransform)
needs to become
let cameraTransform = Transform(matrix: pose.originFromAnchorTransform)
Attachments work differently now, as well, so that for example
} attachments: {
Text("Preview")
.font(.system(size: 100))
.background(.pink)
.tag("previewTag")
}
needs to become
} attachments: {
Attachment(id: "previewTag") {
Text("Preview")
.font(.system(size: 100))
.background(.pink)
}
}
