How do I integrate MFCard with SwiftUI?

MFCard is built with UIKit and does not have native SwiftUI support; you'll need to wrap it in a UIViewControllerRepresentable to use it in SwiftUI projects, which adds complexity.

MFCard vs Stripe iOS SDK: which is better for payment forms?

MFCard focuses on UI and client-side validation, while Stripe SDK provides end-to-end payment processing with tokenization and server integration. Choose MFCard for custom UI needs, but Stripe for full payment functionality.

How to customize MFCard for dark mode in iOS?

You can use the customization options like background colour and label colours to adapt for dark mode, but it requires manual setup as there's no automatic dark mode support mentioned in the README.

Does MFCard support Apple Pay integration?

No, MFCard does not include Apple Pay support; it's designed for manual credit card input and validation, so you'll need to implement Apple Pay separately using PassKit.

How to handle errors when card validation fails in MFCard?

MFCard provides error handling through delegate methods and optional toast messages; you can capture errors in the cardDoneButtonClicked delegate and display custom alerts if needed.

Is MFCard compatible with the latest iOS versions?

The README mentions Swift 5 compatibility with Xcode 11.0, but for newer iOS versions, you may need to check for updates or test thoroughly as the library might not be actively maintained.

What is MFCard?

MFCard is an iOS library written in Swift that provides a customizable credit card input and validation control for mobile applications. It solves the problem of implementing secure, user-friendly payment interfaces by offering a pre-built component with support for major card types, real-time validation, and extensive visual customization.

Target Audience

iOS developers building applications that require credit card payment functionality, particularly those who want a polished, ready-to-use input component without building validation logic from scratch.

Value Proposition

Developers choose MFCard because it offers a beautiful, production-ready credit card interface with comprehensive validation, easy integration via CocoaPods, and extensive customization options that save development time while ensuring a professional user experience.

Overview

Easily integrate Credit Card payments module in iOS App. Swift 4.0

Use Cases

Best For

Adding credit card payment functionality to iOS e-commerce apps
Implementing validated payment forms in Swift-based applications
Creating custom-styled credit card input interfaces
Quickly prototyping payment flows with a pre-built component
Ensuring PCI-compliant card validation for mobile payments
Building apps that support multiple international card types

Not Ideal For

Apps requiring cross-platform payment interfaces (e.g., built with React Native or Flutter)
Projects needing deep, out-of-the-box integration with payment processors like Stripe or PayPal
Teams that require server-side card validation for enhanced security compliance
Applications with highly unique UI designs that deviate significantly from standard credit card layouts

Pros & Cons

Pros

Comprehensive Card Validation

Validates card numbers, expiration dates, and CVC for 12+ card types including MasterCard, Visa, and UnionPay, reducing the need for custom validation logic.

Extensive Customization Options

Offers control over colors, images, corner radius, placeholders, and animations, allowing developers to match app branding without deep UI modifications.

Easy Integration with IBDesignable

All visual properties are editable directly in Interface Builder, speeding up the design process and making it accessible for visual designers.

Interactive User Experience

Includes swipe gestures to flip between card front and back, and presents as an alert-like view, enhancing user engagement.

Cons

Limited Payment Gateway Integration

The library currently lacks built-in support for payment processors; the README lists Stripe integration as a future plan, so additional coding is needed for production payment flows.

Client-Side Validation Only

Relies solely on client-side validation, which may not be sufficient for PCI DSS compliance without server-side checks, potentially posing security risks.

Swift Version Fragmentation

Requires different pod versions for Swift 4 and Swift 5, which can lead to compatibility issues and maintenance overhead in mixed-codebase projects.
