This guide walks you through everything you need to know about integrating Apple’s RoomPlan API into your iOS app, namely:

• What is Apple RoomPlan, and how does it work?
• How to integrate Apple’s RoomPlan API into your iOS app.
• Measurable benefits from the RoomPlan API integration.
• Overcoming RoomPlan API limitations with proven workarounds.
• Advanced use cases powered by It-Jim.

Let’s start by understanding how the Apple RoomPlan API works and its core properties.

What is the Apple RoomPlan API & Its Workflow?

Apple’s RoomPlan API is a framework that uses augmented reality (AR) and the LiDAR Scanner on iPhone and iPad to create 3D models of indoor spaces. This is part of ARKit for building AR apps and using the RoomPlan API.

LiDAR stands for Light Detection and Ranging and uses laser light to measure distances. The technology sends out beams and checks their reflections. RoomPlan API in iOS creates a parametric model that shows the positions and sizes of walls, doors, windows, furniture, and other appliances.

The RoomPlan functionality facilitates automatic object recognition, real-time 3D model reconstruction, and enables easy exports.

Here is a list of potential use cases of an AR app containing the Apple RoomPlan API:

• Real estate: create virtual tours of properties and provide accurate floor plans.
• Architecture: preview and change room layouts in real-time for faster design decisions.
• Interior design: visualize how furniture fits in a room and plan renovations.
• Facility management & Logistics: plan office layouts or maintenance paths, inventory space usage in commercial buildings
• Home repair: estimate material needs for renovating projects and visualize the results.
• Accessibility: help assess room layouts for mobility aids (e.g., wheelchairs), simulate navigation paths for accessible design compliance
• Furniture retail: allows customers to visualize furniture in their homes.
• Marketing: create engaging advertisements or digital promotions.
• Insurance: provide accurate documentation of property layouts and valuable items used for insurance underwriting or claims processing.

Also, RoomPlan’s ability to generate accurate 3D models of indoor spaces makes it well-suited for emergency planning, evacuation modeling, and risk assessment in occupational safety contexts.

Why Apple’s RoomPlan Outperforms Traditional Methods

RoomPlan API in iOS outperforms older methods, such as Scene Reconstruction and manual CAD modeling. It offers faster results, better accuracy, and greater accessibility, all from one mobile device. Traditional 3D scanning produces unstructured point clouds or meshes.

In contrast, RoomPlan API generates a semantic understanding of interior spaces. Instead of just capturing shapes, it identifies and categorizes room elements. The API produces this comprehensive room data within minutes.

Additionally, previous methods required extensive technical expertise, specialized equipment, and considerable post-processing time. 

How Does the Apple RoomPlan API Work?

The process for using the RoomPlan API is straightforward: launch the app, follow the steps to scan the room, and review the results shortly thereafter. You can access and edit the 3D room model anytime.

So, how does Apple RoomPlan API work from a technical perspective?

In brief, the API workflow consists of these three main steps:

1. Scanning

The RoomPlan API uses the device’s camera and LiDAR scanner. It captures the environment and identifies key features: walls, windows, doors, and openings.

2. ML Processing

Sophisticated ML algorithms analyze the captured data to identify room features and create a 3D model of the room. 

3. 3D Output

The RoomPlan API in iOS gives results as parametric data. You can export this data in different Universal Scene Description (USD) formats. This property enables developers to easily add 3D models to their apps.

USD is a typical format for AR-based projects. You can edit these files later in tools like AutoCAD, Shapr3D, or Cinema 4D if needed.

RoomPlan API: Data Structure Overview 

Apple’s RoomPlan can recognize the following aspects of the captured room: 

• Structural elements: walls, doors, windows, openings.
• Furniture: chairs, tables, sofas, beds, storage units.
• Room boundaries: floor plans, room dimensions.
• Spatial relationships: object positioning and room layout connections.

Now, let’s see what data is contained in the 3D model produced by the technology. RoomPlan organizes scanned information into two primary categories: surfaces and objects.

4 Surface Types & Their Data Properties

First, let’s elaborate on surface types, properties, and applicable metrics. RoomPlan identifies four distinct types of surfaces that define a room’s structural boundaries:

1. Wall – primary structural boundary.
2. Door – entry and exit points.
3. Window – light sources and viewing areas.
4. Opening – passages without doors.

Surface Type	Description	Detection Capability	Relevance
Walls	Vertical structural boundaries	Precise positioning and dimensions	Structural layout for AR navigation and space planning
Opennings	Doors, windows, passages	Type identification and measurements	Traffic flow analysis and accessibility planning Useful for layout planning, renovation
Floor	Horizontal base surface	Area calculation and boundaries	Foundation for furniture placement and room use
Furniture	Moveable and built-in objects	Category, size, and spatial relationships	Object interaction and interior design applications

 

Each of these surfaces contains a standardized set of six data properties. 

 

Data Property	Description	Data Type	Notes
Confidence	Detection reliability	Discrete (Low/Medium/High)	Indicates scan quality
Dimensions	Size measurements	Width × Height	Depth always equals 0 (no thickness)
Transform	Position and orientation	4×4 matrix	Standard transformation matrix
Normal	Surface direction	3D vector	Perpendicular to the surface plane
Curve	Surface curvature	Variable/nil	Nil for flat surfaces
Completed edges	Scan completion status	Array	Tracks user scanning progress

15+ Objects & Data Properties

Apple RoomPlan API can detect a variety of objects, namely:

• Furniture: bed, chair, sofa, table.
• Kitchen appliances: dishwasher, oven, refrigerator, sink, stove.
• Bathroom objects: bathtub, toilet, washer, dryer.
• Other: fireplace, stairs, storage, television.

Objects share similar properties to surfaces but with key differences. 

Property values include confidence, dimensions, and transform.

• 3D Dimensions: Full width × height × depth values.
• Oriented Bounding Boxes: Match object orientation, not world coordinates.
• Spatial Relationships: Position relative to walls and other objects.

Dimensions and the transform metric define a bounding box around an object. The bounding box isn’t aligned with the axes. Instead, it matches the object’s orientation, not the world coordinate axes.

Data Property	Description	Object vs. Surface Difference
Confidence	Detection reliability	Same discrete values (Low/Medium/High)
Dimensions	Size measurements	3D values (width × height × depth)
Transform	Position and orientation	Defines a non-axis-aligned bounding box

As understood, RoomPlan API can detect and visualize many elements. Additionally, it cannot simply be visualized as plain boxes; however, you can replace them with real furniture models to make the scan more detailed and valuable.

This structured method makes RoomPlan data ideal for creating top-notch AR apps, architectural analysis, and automated space planning.

Getting Started with the Apple RoomPlan API: Tech Perspective 

Developers can seamlessly use the RoomPlan API in their iOS apps using one of two approaches:

• Basic integration: add a RoomPlan API with minimal effort and without customization. Users will interact with the built-in solution experience only.
• Advanced integration: gain complete control over scanning parameters and real-time data processing. From this perspective, users can build detailed room plans and edit specific elements as needed.

Thus, the easiest way to integrate Apple’s RoomPlan API into your iOS app is by using the default RoomCaptureView in Storyboard.

RoomPlan follows a clear component hierarchy: 

 

The most straightforward integration uses the default RoomCaptureView for Storyboard.

1. The RoomCaptureView handles all visualizations and interactions with the end user. 
2. A user scans the room with RoomCaptureSession, accessed via the corresponding view’s property. 
3. The RoomCaptureSession itself utilizes the standard ARSession from ARKit.

Overcoming Apple’s RoomPlan API Limitations 

Note that RoomPlan is still a new API. Some things may change, and issues might get fixed in future updates. 

However, RoomPlan delivers useful but not perfectly accurate results. Measurements and object positions may have minor errors, which is excellent for quick scans but not reliable for precision-oriented tasks.

Since our team has had an immersive experience with the Roomplan API, we’ve identified its key limitations and know how to work around them.

How we work with existing API limitations, read also:

RoomPlan is Awful, and it’s Great!

For example, the RoomPlan framework has significant constraints, including the requirement for rectangular simplifications. The system attempts to reduce all objects and surfaces to a set of rectangles. 

Additionally, the technology does not capture data from ceilings or skylights.

The current version of the RoomPlan API in iOS has several constraints, such as:

• Limited object recognition – detects only a fixed set of common household items (e.g., chairs, tables, sofas). It does not identify less typical objects, such as water boilers or industrial equipment.
• Struggles with multiple or large rooms – not designed for scanning numerous or very large spaces in one go. Apple recommends a maximum of about 9×9 m (30×30 ft). Longer scans degrade tracking accuracy, risk overheating, and may lead to drift.
• Measurement Errors – shows measurement drift—errors up to ±5 cm per wall.
• Incorrect Wall Thickness – models all walls as a uniform thickness of around 16 cm, regardless of real measurements. Exterior walls are always that thin; structures over ~50 cm break into two separate thin walls.
• Door & Window Flaws – merge double doors or door-window combinations incorrectly.
• Mirrored Surface Issues – large mirrors and mirrored wardrobes can confuse LiDAR, leading to missing geometry or phantom objects.
• Surface shape limitations – assume surfaces are rectangular or slightly curved, so it misrepresents angled walls, arched openings, or detailed trim.
• Phantom (ghost) geometry – occasionally “sees” surfaces or objects that don’t exist; LiDAR noise can lead to phantom walls or objects.
• No Ceiling or skylight capture – does not capture ceilings or skylights, making it unsuitable for tasks requiring lighting design or accurate volume measurements.

 

While powerful, RoomPlan isn’t perfect in every environment. With years of vision-based R&D, we know how to work with these and other limitations.

Apple continuously improves RoomPlan API capabilities with each iOS platform update. Our AI iOS development services and approach account for this evolution.

“We are leveraging new RoomPlan features as they’re released. Our clients enjoy Apple’s upgrades while keeping current features intact. This is the benefit of working with a team that knows the framework’s roadmap and even beyond.” 

– Yurij Gapon, Head of iOS at It-Jim
