Poly is an unofficial Google Poly SDK, written in Swift.

This library makes it easy to integrate with Google Poly while providing a few additional client-side features.

🔍 3D model search
3D model download management
📦 advanced 3D data caching
📡 Poly reachability support
🐦 Swift 5.0

Need a different version of Swift?

  • 5.0 - Target your Podfile to the latest release or master (will push when Cache updates)
  • 4.2 - Target your Podfile to the swift4.2 branch


Before you begin, ensure that you have read Google’s Poly documentation, understand best practices for attribution, and have generated your API key.

Quick Start

The sample project provides several examples for integration.

You can install the dependencies with the command pod install or by running the makefile commands make setup && make pods.

# CocoaPods

pod "Poly", "~> 0.4.0"

# Carthage

github "piemonte/Poly" ~> 0.4.0

# Swift PM

let package = Package(
    dependencies: [
        .Package(url: "https://github.com/piemonte/Poly", majorVersion: 0)

Alternatively, drop the source files into your Xcode project.


Import the library.

import Poly

Setup your API key.

Poly.shared.apiKey = "REPLACE_WITH_API_KEY"

List assets using keywords.

Poly.shared.list(assetsWithKeywords: ["fox"]) { (assets, totalCount, nextPage, error) in
	// assets array provides objects with information such as URLs for thumbnail images

// you may also query for the data directly for your own model creation

Poly.shared.list(assetsWithKeywords: ["fox", "cat"]) { (data, error) in

Get independent asset information.

Poly.shared.get(assetWithIdentifier: "10u8FYPC5Br") { (asset, count, page, error) in
	// asset object provides information such as URLs for thumbnail images

// you may also query for the data directly for your own model creation

Poly.shared.get(assetWithIdentifier: "10u8FYPC5Br") { (data, error) in

Download a 3D asset and its resources for rendering, either using the asset identifier or the asset model object itself.

Poly.shared.download(assetWithIdentifier: "10u8FYPC5Br", progressHandler: { (progress) in
}) { (rootFileUrl, resourceFileUrls, error) in
    if let rootFileUrl = rootFileUrl {
        let node = SCNNode.createNode(withLocalUrl: rootFileUrl)

The API also provides private object loading but additional endpoints may need to be added. Auth support is setup and available via the authToken property.
