I am currently working on creating a virtual interior design app. Can an app made with the Room Plan API be used on iPhones without LIDAR? If so, how much accuracy would be lost compared to iPhones with LIDAR?

Can an app made with the Room Plan API be used on iPhones without LIDAR? If so, how much accuracy would be lost compared to iPhones with LIDAR? If not, is there an API similar to RoomPlan that works on iPhones without LiDAR?

Hello everyone! I'm developing an app with this amazing RoomPlan API, so far everything works great, however I want to render a customized viewer and I don't want draw default 3D geometry, the line shapes are very helpful so I want to keep them. Is there any way to disable the 3D geometry shown on the viewr? I could just render another viewer ontop of the room capture viewer however I want to save as much resources as possible.

We're developing an iOS application that integrates RoomCaptureSession with ARSCNView for room scanning. Our implementation differs from the standard RoomCaptureView because we need custom UI guidance with 3D dots placed in the scanning environment to guide users through the capture process. Bug Description: The application crashes when users attempt to scan multiple rooms or apartments in sequence. The crash specifically occurs with the following pattern: User successfully scans first room with multiple hotspots (working correctly) User stops scanning, moves to a new room In the new room, first 1-2 hotspots work correctly Application crashes when attempting to scan additional hotspots Technical Details: Error: SLAM Anchor assertion failure in SlamAnchor.cpp:37 : HasValidPose() Crash occurs in Thread 27 with CAPIDetectionOutputFwdNode Error suggests invalid positioning when placing AR anchors Steps to Reproduce: Start room scan Complete multiple hotspot captures in first room Stop scanning Start new room scan Capture 1-2 hotspots successfully Attempt additional hotspot captures -> crashes Attempted Solutions: Implemented anchor cleanup between sessions Added position validation before anchor placement Implemented ARSession error handling Added proper thread management for AR operations Environment: Device: iPhone 14 Pro (LiDAR equipped) iOS Version: 18.1.1 (22B91) Testing through TestFlight Crash Log Details: Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Triggered by Thread: 27 Thread 27 Crashed: 0 libsystem_kernel.dylib 0x00000001f0cc91d4 __pthread_kill + 8 1 libsystem_pthread.dylib 0x0000000228e12ef8 pthread_kill + 268 2 libsystem_c.dylib 0x00000001a86bbad8 abort + 128 3 AppleCV3D 0x0000000234d71a28 cv3d::vio::capi::SlamAnchor::SlamAnchor Question: Is there a recommended approach for handling multiple room captures with custom ARSCNView integration? The standard RoomCaptureView implementation doesn't show this behavior, but we need the custom guidance functionality that ARSCNView provides. Crash Log Code and full crash logs can be provided if needed.

Hi everyone, I’m currently developing an app using Apple’s RoomPlan framework, and so far, everything is working great! However, I’d like to extend the functionality to include scanning smaller objects, such as light switches or power outlets, in addition to the walls and larger furniture that RoomPlan already supports. From what I understand, based on the documentation, RoomPlan doesn’t natively support the detection or measurement of smaller objects like these. Is that correct? If that’s the case, does anyone have suggestions or ideas on how this could be achieved? Perhaps by integrating another framework or technology alongside RoomPlan? I’d appreciate any insights or advice from those who have worked on similar use cases. Thanks in advance!

When using RoomPlan to collect data and processing it with StructureBuilder, the app crashes. Crash thread: RoomScanCore.offlineFloorPlanGeneration How should I deal with this issue? I’ve already implemented crash capture, but no crash was logged—the app just crashes directly. RoomScanCore.offlineFloorPlanGeneration

Lately i got a lot of crashes on iOS 18 devices (mostly 13 Pro devices but also a 16 Pro Max), has anyone encountered similar issues and is there more information about offlineFloorPlanGeneration? com.apple.RoomScanCore.offlineFloorPlanGeneration EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000f5cab18e03c0 RoomScanCore RSFrameFromDictionary + 110992

I created an app where the user: first scans a room using RoomCaptureView (RoomPlan) then taps on physical elements (objects, walls...) using an ARView to record some 3d positions I can handle taps in an ARView using a UITapGestureRecognizer and the ARView raycast(from:, allowing:, alignment:) method. This works fine, so I thought I could do the same using the ARView used by RoomCaptureView., so the user can scan a room and record some 3d positions at the same time. Sadly, this approach does not work, as the raycast method always returns nil. What I actually need is mapping a tap on screen to a real-world position during RoomCaptureSession. Does anyone know how to do this?

Hi all, Our app allows a user to scan a room and then save that scan on a separate view, followed by additional scans. We're looking into allowing room combining via CapturedStructure, so we need rooms to be scanned in the same ARWorldMap without necessarily needing to re-localize in the same session. This should fit within the first scenario that Apple described. The only way I have found that allows our requirements is to save RoomCaptureView and to re-use that RoomCaptureView whenever we need to start a session again. This creates a number of other issues, and ideally, we wouldn't need to save a View in something like a singleton. We are using captureSession.stop(pauseARSession: false). Additionally, if we use the same RoomCaptureView and an error occurs during the scanning process, we can't get the instructions overlay to appear again if we reuse this view (specifically, the instructions in the middle of the view that state "Move device to start"). It's as if the instructions are completely removed and scanning is stuck on an error state if an error occurs. These instructions also seem to be separate from the instructions we can grab from RoomCaptureViewDelegate via didProvide instruction: RoomCaptureSession.Instruction), so we can't use that either. There's a couple subviews that seem relevant to this: RoomCaptureCoachingOverlayView and ARGlyphView - but both are not public, so we can't force them to appear. Also attempted a number of other things to try to get these subviews to appear, such as layoutIfNeeded(). Saving the ARSession and using it in let roomCaptureView = RoomCaptureView(frame: viewBounds, arSession: arSession) where we're creating a new view with the same ARSession seems much more ideal as that solves the above issues, but we run into another issue: world tracking seems to be completely lost when a new RoomCaptureView (and thus a new RoomCaptureSession) is started, even with the same already started ARSession, almost as if captureSession.stop(pauseARSession: false) doesn't work as described. Is there any way around needing to use the same RoomCaptureView or RoomCaptureSession for subsequent scans in the same session without needing to re-localize via ARWorldMap loading? Is there a way to force the guiding instructions to appear?
