The deepidv iOS SDK puts identity verification inside your app. It ships the capture screens your users see (ID document, selfie, face liveness) and the calls behind them, so a complete verification is one SwiftUI view. ![Four iPhone screens in a row: an ID card held in the capture frame with 'Hold still', a selfie taken in the oval with a green tick, the liveness ring filling around a face, and the 'Thanks, you're done' screen.](https://mintcdn.com/deep-identity-inc/KR_jLd52VE3haGnp/images/ios/overview-flow.webp?fit=max\&auto=format\&n=KR_jLd52VE3haGnp\&q=85\&s=9ddecc1e06a12418ab52ccaa0959a884) A workflow on iPhone: ID capture, selfie, face liveness, and the closing screen. ## What's included | Area | What you get | | - | - | | [Workflows](https://docs.deepidv.com/integrate/sdks/ios/workflows/run-a-workflow.md) | `DeepIDVWorkflowView` runs a verification workflow you built in the Admin Console, step by step: ID verification (up to three documents), face liveness, retries, resuming and a closing screen. | | [Document capture](https://docs.deepidv.com/integrate/sdks/ios/document-capture.md) | Guided capture of ID cards, driver's licenses and passports. Recognizes the document, catches a card held upside down, refuses health cards, captures automatically and falls back to a manual shutter. | | [Selfie](https://docs.deepidv.com/integrate/sdks/ios/selfie.md) | A front-camera selfie with face guidance. | | [Face liveness](https://docs.deepidv.com/integrate/sdks/ios/face-liveness.md) | A native liveness check (head movement, optionally with a colored-light sequence), scored by deepidv. | | [Re-verification](https://docs.deepidv.com/integrate/sdks/ios/re-verification.md) | Confirms a returning user is the same person, with their face. | | [Drop-in verification](https://docs.deepidv.com/integrate/sdks/ios/drop-in-verification.md) | ID and selfie in one view, without a workflow. | | [Headless API](https://docs.deepidv.com/integrate/sdks/ios/headless/document-and-identity.md) | `async` methods for images you captured yourself: document scan, identity verify, liveness and iGaming checks. | | [Branding](https://docs.deepidv.com/integrate/sdks/ios/branding.md) and [languages](https://docs.deepidv.com/integrate/sdks/ios/languages.md) | Your colors, fonts and corner radius; English, Spanish and French. | ## Requirements * iOS 15 or later * Xcode 26 or later (Swift 6.2) * `NSCameraUsageDescription` in your app's `Info.plist` * No third-party dependencies: the SDK uses Apple frameworks only ## How it fits together Your app runs the screens. Your backend holds the deepidv API key, creates sessions, and receives the decision. ```mermaid theme={null} flowchart LR A[Your iOS app
deepidv SDK] -- "SDK requests" --> B[Your backend
proxy] B -- "x-api-key" --> C[deepidv API] A -. "photos (presigned uploads)" .-> D[(deepidv storage)] C -- "webhook: decision" --> B ``` * The SDK never needs your secret API key on the device. Route its requests through your backend, which adds the key. See [Security and API keys](https://docs.deepidv.com/integrate/sdks/ios/security-and-api-keys.md). * Photos upload straight to deepidv storage through short-lived presigned URLs, so your backend doesn't carry images. * The decision reaches your backend through [webhooks](https://docs.deepidv.com/webhooks/overview.md) and `GET /v1/sessions/{id}`. The SDK's result is for your UI, not for granting access. ## What do you want to do? | Goal | Start here | | - | - | | Verify a new user with ID and face | [Quickstart](https://docs.deepidv.com/integrate/sdks/ios/quickstart.md), then [Run a workflow](https://docs.deepidv.com/integrate/sdks/ios/workflows/run-a-workflow.md) | | Pick the right integration | [Choose an integration](https://docs.deepidv.com/integrate/sdks/ios/choose-an-integration.md) | | Confirm a returning user | [Re-verification](https://docs.deepidv.com/integrate/sdks/ios/re-verification.md) | | Build your own screens around our capture | [Document capture](https://docs.deepidv.com/integrate/sdks/ios/document-capture.md), [Selfie](https://docs.deepidv.com/integrate/sdks/ios/selfie.md), [Face liveness](https://docs.deepidv.com/integrate/sdks/ios/face-liveness.md) | | Use photos you already have | [Headless API](https://docs.deepidv.com/integrate/sdks/ios/headless/document-and-identity.md) | | Match your brand | [Branding](https://docs.deepidv.com/integrate/sdks/ios/branding.md) | | Ship safely | [Security and API keys](https://docs.deepidv.com/integrate/sdks/ios/security-and-api-keys.md), [Proxy mode](https://docs.deepidv.com/integrate/sdks/ios/proxy-mode.md) | | Let an AI assistant do the integration | [Build with AI](https://docs.deepidv.com/integrate/sdks/ios/ai-agents.md) | ## Source and releases The SDK is open source under the MIT license: [github.com/Deep-Identity-Inc/deepidv-sdk-swift](https://github.com/Deep-Identity-Inc/deepidv-sdk-swift).
