Weavr iOS SDK

Documentation: https://docs.weavr.io/sdks/ios/

Native iOS SDK (Swift) for embedding PCI-compliant financial services components with biometric authentication support.

Prerequisites

  • Xcode 16+
  • Swift 5.9+
  • Minimum iOS 15.1

Setup

Option 1: Swift Package Manager (recommended)

File > Add Package Dependencies > Enter:

https://github.com/weavr-io/secure-components-ios.git

Option 2: CocoaPods

# Podfile
source 'https://cdn.cocoapods.org'
source 'https://github.com/nicklockwood/iVersion.git'

pod 'WeavrComponents'
pod 'Approov', :podspec => 'https://raw.githubusercontent.com/nicklockwood/iVersion/master/Approov.podspec'

Required permissions (Info.plist)

<key>NSPhotoLibraryUsageDescription</key>
<string>Upload identity documents</string>
<key>NSCameraUsageDescription</key>
<string>Capture identity documents and selfie</string>
<key>NSMicrophoneUsageDescription</key>
<string>Required for video verification</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Verify your location during onboarding</string>
<key>NSFaceIDUsageDescription</key>
<string>Authenticate with Face ID</string>

Initialize

import WeavrComponents

// Set Firebase App Check token (if using biometrics)
UXComponents.setAppCheckToken(token)

// Initialize
UXComponents.initialize(env: .SANDBOX, uiKey: "your_ui_key")

Components

Input components

// Password field
let passwordField = SecurePasswordField()
passwordField.placeholder = "Enter password"
view.addSubview(passwordField)

// Passcode field
let passcodeField = SecurePasscodeField()
view.addSubview(passcodeField)

// Segmented passcode (PIN-style boxes)
let segmentedPasscode = SecurePasscodeFieldStack()
view.addSubview(segmentedPasscode)

// Tokenize
passwordField.tokenize { token in
    // Send token to your server
}

Display components

// Card number
let cardNumber = SecureCardNumberTextView()
cardNumber.cardId = "card_id"
cardNumber.accessToken = bearerToken
view.addSubview(cardNumber)

// CVV
let cvv = SecureCVVTextView()
cvv.cardId = "card_id"
cvv.accessToken = bearerToken
view.addSubview(cvv)

// Card PIN
let cardPin = SecureCardPINTextView()
cardPin.cardId = "card_id"
cardPin.accessToken = bearerToken
view.addSubview(cardPin)

Biometric authentication

// Enroll
UXComponents.psa.enroll { result in
    switch result {
    case .success:
        // Enrolled
    case .failure(let error):
        // Handle error
    }
}

// Authenticate
UXComponents.psa.authenticate { result in
    switch result {
    case .success(let token):
        // Use token for API calls
    case .failure:
        // Fallback to passcode
    }
}

Theming

let branding = BrandingConfig(
    primaryColor: UIColor(hex: "#1A73E8"),
    textColor: UIColor(hex: "#333333"),
    font: UIFont(name: "CustomFont", size: 16),
    buttonCornerRadius: 8
)
UXComponents.setBranding(branding)

Storyboard integration

Components can also be added via Interface Builder:

  1. Add a UIView to your storyboard
  2. Set the class to the desired component (e.g., SecurePasswordField)
  3. Set the module to WeavrComponents
  4. Configure properties via the Attributes inspector

Common pitfalls

  • Permissions required: KYC components need camera, photo library, and location permissions — missing these causes silent failures.
  • Dynamic linking: Approov framework requires dynamic linking — ensure "Embed & Sign" is set in Xcode.
  • Firebase required: Biometric auth and push provisioning need Firebase App Check configured.
  • Initialize before use: Call UXComponents.initialize() in AppDelegate or early in the app lifecycle.
  • Step-up for display: Card number, CVV, and PIN display require step-up authentication first.
