• To improve the experience of visually impaired users.

JIRA ticket

🛠 How

• Creating a new property accessibilityLabel on the PaymentType enum.
• Pre-pending the value of the property to the cardNumberAccessibilityLabel string if the payment was made using either ApplePay or GooglePay.

♿️ Accessibility

• Works with VoiceOver

✅ Acceptance criteria

With VoiceOver enabled , select a backed project, go to the ManagePledge screen, and tap the Ending in XXXX label.

• If the project was backed using credit card, VoiceOver should say [Card issuer], ending in [Card number]
• If the project was backed using ApplePay, VoiceOver should say Apple Pay, [Card issuer], ending in [Card number]
• If the project was backed using Android/Google Pay, VoiceOver should say Google Pay, [Card issuer], ending in [Card number]

If PaymentType is .creditCard, voice over doesn't need to say anything.
