I placed 3d object to ARViewController after 3 seconds of placing object, then I want to rotate object by 90degree arView.scene.addAnchor(anchorEntity) DispatchQueue.main.asyncAfter(deadline: .now() + 3){ print("after 3 sec ! ") let radians = 90.0 * Float.pi / 180.0 anchorEntity.orientation = simd_quatf(angle: radians, axis: SIMD3(x: 0, y: 1, z: 0)) } it works very well but the problem is that I want to smooth rotation , as you can see short video, it suddenly rotate which seem weird. how can I do this ? https://youtu.be/Ixk2elm-bfU

I'm testing code with destination sample app but I really don't know how to add button beside of title in playbackcontrols. I can add button with customoverlay and customInfoViewControllers but it is not like apple tv's seat change button . how can I add button ?

reference : https://wjwickham.com/posts/refreshing-data-in-the-background-on-watchOS/ on init function , which mean, for every 5 min it should come to handle function in Extension Delegate.swift but it won't come to handle any anything else that I should do ? let preferredDate = Date().addingTimeInterval(60 * 5)// 5min later preferredDate, userInfo: nil) { (error) in WKExtension.shared().scheduleBackgroundRefresh(withPreferredDate: preferredDate, userInfo: nil) { (error: Error?) in guard error == nil else { print("Couldn't schedule background refresh.") return } print("Scheduled next background update task for: \(preferredDate)") } ExtensionDelegate.swift // // ExtensionDelegate.swift // Coffee Tracker WatchKit Extension // // Created by pedro jung on 2022/06/15. // Copyright © 2022 Apple.

there's position which is simd3 and there 's anchorEntity. I want to get distance between two. how I did is var distance = distance(position, ( self.modelentity.position(relativeTo:nil) ) var distance = distance(position, ( self.modelentity.position ) but both failed because it seems calculating distance between world origin anchor not distance between position to self.modelentity. how can I calculate distance ?
