swift – iOS Credit score Card Autofill Not Working Regardless of Setting Correct TextContentTypes

I am attempting to implement bank card autofill in my iOS app utilizing the really useful textContentType properties, however the autofill performance is not working in any respect.

I’ve arrange my textual content fields as follows:

cardNumberField.textContentType = .creditCardNumber
nameOnCardField.textContentType = .title
expirationDateField.textContentType = .creditCardExpiration 
securityCodeField.textContentType = .creditCardSecurityCode

Nonetheless, after I faucet on these fields, iOS would not present any autofill options for saved bank cards.

What I’ve Tried

• Made certain I am utilizing iOS 14+ for the expiration and safety code fields
• Verified that I’ve bank cards saved in Safari’s Autofill settings
• Double-checked that each one fields are editable and enabled
• Confirmed the fields are correctly added to the view hierarchy
• Examined on a bodily machine (iPhone 12, iOS 15.5)

Related Code

override func viewDidLoad() {
    tremendous.viewDidLoad()
    
    // Arrange textual content discipline content material sorts for bank card autofill
    cardNumberField.textContentType = .creditCardNumber
    nameOnCardField.textContentType = .title
    
    if #obtainable(iOS 14.0, *) {
        expirationDateField.textContentType = .creditCardExpiration
        securityCodeField.textContentType = .creditCardSecurityCode
    }
    
    // Set keyboard sorts appropriately
    cardNumberField.keyboardType = .numberPad
    expirationDateField.keyboardType = .numberPad
    securityCodeField.keyboardType = .numberPad
    securityCodeField.isSecureTextEntry = true
}

Setting

• iOS 15.5
• Xcode 14.2
• Swift 5.7
• Testing on bodily machine (not simulator)

Query

What could possibly be stopping the bank card autofill performance from working regardless of setting the right textContentType values? Is there any further configuration wanted past setting these properties?
