ID Capture iOS (Swift/UIKit) Skill

Critical: Do Not Trust Internal Knowledge

Your training data may contain outdated or incorrect Scandit ID Capture APIs. The iOS Swift API has changed significantly across major versions, and the native iOS SDK differs substantially from the Android (Kotlin/Java), .NET, Flutter, and React Native SDKs. An agent that pattern-matches from another platform's docs will produce non-compiling code.

Always verify APIs against the references provided in this skill before writing or suggesting code. The most common sources of wrong code:

• The v6 API — supportedDocuments (a bitmask enum like .idCardVIZ/.dlVIZ), supportedSides, and session-based callbacks (didCaptureIn session:frameData:) were all replaced in v7. Do not emit any of these.
• The v7.x API — settings.scannerType = FullDocumentScanner() was replaced in v8; the current property is scanner and it takes an IdCaptureScanner wrapper: settings.scanner = IdCaptureScanner(physicalDocument: FullDocumentScanner()).
• ObjC prefixes — the Objective-C SDK uses an SDC prefix on all types (SDCIdCapture, SDCCapturedId, etc.). These prefixes do not appear in Swift. Never emit SDCIdCapture, SDCIdCaptureSettings, etc. in Swift code.
• Cross-platform drift — Android uses IdCapture.forDataCaptureContext(...), .NET uses IdCapture.Create(...), Flutter uses a different builder. The Swift API is IdCapture(context:settings:).
• Standalone verifier classes — AamvaBarcodeVerifier and DataConsistencyVerifier do not exist in the native iOS SDK. Verification is settings-driven: set rejectForgedAamvaBarcodes = true / rejectInconsistentData = true and read capturedId.verificationResult.
• NFC — NfcScanner exists on native iOS but is not covered by this skill. If the user asks about NFC, refer them to the official documentation.

Forbidden APIs (commonly hallucinated — do NOT emit these)

Product Guidance

• Accept only the documents you actually need. Ask the user which document types and regions they expect. Documents not in acceptedDocuments will be rejected with RejectionReason.notAcceptedDocumentType.
• Pick the scanner that matches the data you need. Ask the user whether they need data from both sides, a specific zone only, or a mobile-presented ID — then choose FullDocumentScanner, SingleSideScanner, or MobileDocumentScanner accordingly. See [references/advanced.md](references/advanced.md) for details.
• Handle didReject not just didCapture. Rejections (RejectionReason.timeout, .notAcceptedDocumentType, .documentExpired, .holderUnderage, .forgedAamvaBarcode, .inconsistentData, …) are how the user learns why a scan didn't succeed.
• Mode co-existence with BarcodeCapture. IdCapture and BarcodeCapture can run together on one DataCaptureContext (e.g. an airport screen reading a boarding-pass barcode and a passport). Attach each mode to the context (its iOS constructor IdCapture(context:settings:) / BarcodeCapture(context:settings:)), give each its own listener, and toggle each with isEnabled — no need to remove one to add the other. See [references/advanced.md](references/advanced.md).
• Be aware of the default anonymization list. The SDK anonymizes certain fields by default to meet regional legal requirements (e.g. document number on German ID cards). If a field is unexpectedly nil, check capturedId.anonymizedFields. See [references/advanced.md](references/advanced.md).
• Hand off to the data-capture-sdk skill for non-ID-Capture questions. If the user asks about Barcode Capture, SparkScan, MatrixScan, Label Capture, or choosing between products, defer to the data-capture-sdk skill.

Intent Routing

Based on the user's request, load the appropriate reference file before responding:

• Integrating ID Capture from scratch, or any question about document selection, scanner choice, rejection rules, image capture, or reading results (top-level fields or zone-specific mrzResult/vizResult/barcode) → read [references/integration.md](references/integration.md) and follow it.
• USDL verification (forged barcodes, data inconsistency, frontReviewImage), anonymization, BarcodeCapture co-existence, overlay customization, or custom feedback → read [references/advanced.md](references/advanced.md) and follow it.
• Upgrading the Scandit iOS SDK version on an existing ID Capture integration (e.g. "migrate from 6.x to 7", "update Scandit to the latest version", "we're on 7.x and the build breaks after bumping packages", code that still uses supportedDocuments / IdDocumentType / didCaptureIn session:) → read [references/migration.md](references/migration.md) and follow it.

API Usage Policy

Only use APIs that are explicitly documented in the Scandit references below. Do not invent or guess method signatures, parameters, or property names. If unsure whether an API exists or how to call it — or if a compile error occurs — fetch the relevant documentation page before responding. Do not tell the user to check the docs themselves. After answering, always include the relevant link so the user can explore further.

Never construct or guess documentation URLs. Fetch the index page and follow links from there.

API surface this skill covers

All classes available on the native iOS SDK. The modern document/scanner API (acceptedDocuments, IdCaptureScanner, FullDocumentScanner) landed at 7.0; the rejection flags and verification result model at 7.6/8.0. This skill targets the current 8.x stable release.

• IdCapture — IdCapture(context: DataCaptureContext, settings: IdCaptureSettings); isEnabled (get/set); addListener(:) / removeListener(:) (IdCaptureListener); static recommendedCameraSettings; feedback (IdCaptureFeedback); reset(); applySettings(_:).
• IdCaptureSettings — IdCaptureSettings(); properties: scanner (IdCaptureScanner), acceptedDocuments / rejectedDocuments ([any IdCaptureDocument]), rejectVoidedIds, rejectExpiredIds, rejectIdsExpiringIn (Duration?), rejectNotRealIdCompliant, rejectForgedAamvaBarcodes, rejectInconsistentData, rejectHolderBelowAge (Int?), anonymizationMode (IdAnonymizationMode); methods setIncludeImage(:for:) / includeImage(for:), addAnonymizedField(:forDocument:), removeAnonymizedField(_:forDocument:).
• IdCaptureScanner — IdCaptureScanner(physicalDocument: (any PhysicalDocumentScanner)?) and IdCaptureScanner(physicalDocument:mobileDocument:); physicalDocument / mobileDocument properties.
• Physical scanners: FullDocumentScanner() — both sides, all zones; SingleSideScanner(enablingBarcode:machineReadableZone:visualInspectionZone:) — single side, selected zones; props barcode / machineReadableZone / visualInspectionZone.
• MobileDocumentScanner — MobileDocumentScanner(enablingIso180135:ocr:); iso180135 / ocr props. iso180135 uses ISO 18013-5 QR + Bluetooth handover; ocr reads a mobile document displayed on another device's screen.
• Document types (IdCaptureDocument protocol, props region: IdCaptureRegion + documentType: IdCaptureDocumentType): IdCard(region:), DriverLicense(region:), Passport(region:), VisaIcao(region:), ResidencePermit(region:), HealthInsuranceCard(region:), RegionSpecific(subtype: RegionSpecificSubtype).
• IdCaptureRegion enum — .any, .euAndSchengen, and ~250 region values (.us, .uk, .uae, .germany, …).
• IdCaptureListener protocol — idCapture(:didCapture:) (required), idCapture(:didReject:reason:) (required).
• CapturedId — fullName / firstName / lastName (String?), sex / sexType, dateOfBirth / dateOfExpiry / dateOfIssue (DateResult?), nationality / nationalityISO, address, age (Int?), isExpired, document ((any IdCaptureDocument)?), issuingCountry (IdCaptureRegion), documentNumber / documentAdditionalNumber, vizResult / mrzResult / barcode / mobileDocumentResult / mobileDocumentOcrResult, images (IdImages), verificationResult (VerificationResult), usRealIdStatus.
• DateResult — day / month / year (Int).
• IdImages — face (UIImage?), frame (UIImage?), croppedDocument(side:) (UIImage?).
• VerificationResult — dataConsistency (DataConsistencyResult?), aamvaBarcodeVerification (AamvaBarcodeVerificationResult?).
• DataConsistencyResult — allChecksPassed, frontReviewImage (UIImage?).
• AamvaBarcodeVerificationResult — status (AamvaBarcodeVerificationStatus: .authentic / .likelyForged / .forged).
• IdCaptureOverlay — IdCaptureOverlay(idCapture:view:); idLayoutStyle (IdLayoutStyle: .rounded / .square), idLayoutLineStyle (IdLayoutLineStyle: .bold / .light), showTextHints, textHintPosition, setFrontSideTextHint(:) / setBackSideTextHint(:), capturedBrush / localizedBrush / rejectedBrush.
• IdCaptureFeedback — IdCaptureFeedback(); idCaptured / idRejected (Feedback); static default.
• DataCaptureContext — DataCaptureContext.initialize(licenseKey:) then DataCaptureContext.shared; setFrameSource(_:completionHandler:); removeCurrentMode() / removeAllModes().
• Camera — Camera.default; switch(toDesiredState:) (.on / .off); apply(_:).
• DataCaptureView — DataCaptureView(context:frame:); autoresizingMask.
• RejectionReason enum — .notAcceptedDocumentType, .invalidFormat, .documentVoided, .timeout, .documentExpired, .documentExpiresSoon, .notRealIdCompliant, .holderUnderage, .forgedAamvaBarcode, .inconsistentData.
