How do I add form validation in SwiftForms?

SwiftForms doesn't include built-in validation; you need to implement it manually by checking row values after submission or using custom cells with validation logic. Refer to the custom cells section in the README for extending functionality with methods like update().

SwiftForms vs Eureka: which is better for iOS forms?

SwiftForms is lighter and more minimal, ideal for quick setups with deep customization, while Eureka offers more features out-of-the-box like built-in validation. Choose SwiftForms for simplicity and flexibility, Eureka for comprehensive functionality with less coding.

How to create a custom cell in SwiftForms?

Subclass FormBaseCell and override the configure() and update() methods, then set the cellClass property in FormRowDescriptor. The README provides example methods and highlights the need to define formRowCellHeight() for proper sizing.

Does SwiftForms work with SwiftUI?

No, SwiftForms is built for UIKit and requires FormViewController, so it's not natively compatible with SwiftUI. You'd need to wrap it in a UIViewControllerRepresentable for use in SwiftUI projects, which adds complexity.

Can I use SwiftForms for dynamic forms with conditional fields?

Yes, but you'll need to manually update the form descriptor by adding or removing rows based on conditions, as the library doesn't provide built-in reactivity. This requires additional code to manage form state changes.

What are the alternatives to SwiftForms for building forms in Swift?

Alternatives include Eureka for feature-rich forms, IGListKit for complex list-based interfaces, or Apple's UITableView with custom cells. SwiftForms is best suited for lightweight, declarative form creation where customization is a priority.

What is SwiftForms?

SwiftForms is a lightweight Swift library designed to simplify form creation in iOS applications. It allows developers to define forms declaratively with minimal code, handling sections, rows, and input types efficiently. The library solves the problem of repetitive and complex form-building tasks by providing a structured and customizable approach.

Target Audience

iOS developers building applications that require user input forms, such as settings screens, registration pages, or data entry interfaces. It is particularly useful for those seeking a balance between ease of use and customization flexibility.

Value Proposition

Developers choose SwiftForms for its simplicity in quickly creating forms while offering deep customization through configurable cells and selector controllers. Its lightweight nature and compatibility with dependency managers like CocoaPods and Carthage make it a practical choice for modern iOS projects.

Overview

A small and lightweight library written in Swift that allows you to easily create forms.

Use Cases

Best For

Building registration or login forms in iOS apps
Creating settings or configuration screens with multiple input types
Developing data entry interfaces with custom validation or styling
Implementing forms that require dynamic or conditional fields
Prototyping iOS applications that need quick form integration
Adding customizable form components to existing Swift projects

Not Ideal For

Apps built with SwiftUI that prefer native form components and declarative syntax
Projects requiring drag-and-drop form builders or low-code solutions with minimal coding
Teams needing extensive built-in validation, error handling, or real-time form logic without additional implementation
Large-scale applications with complex, multi-step forms that benefit from more integrated frameworks or state management

Pros & Cons

Pros

Declarative Simplicity

Allows defining forms, sections, and rows in just a few lines of code, as shown in the README example for creating an email and password form with minimal boilerplate.

Flexible Customization

Provides a configuration dictionary for cell appearance and supports custom cells by subclassing FormBaseCell, enabling fine-grained control over design and behavior.

Extensible Architecture

Implements protocols like FormSelector for custom selector controllers, allowing developers to design unique selection interfaces as per the README's guidance.

Easy Integration

Compatible with CocoaPods and Carthage, as specified in the README, making dependency management straightforward for modern iOS projects.

Cons

Manual Setup Burden

Customization requires subclassing and implementing methods like configure() and update(), which can be verbose and time-consuming compared to drop-in solutions with pre-styled components.

Limited Modern Features

Based on XLForm and targeting iOS 8.0+, it lacks support for newer iOS APIs, SwiftUI, or Combine, potentially limiting its relevance for cutting-edge development.

Sparse Built-in Validation

The README does not mention form validation features, forcing developers to implement validation logic manually, adding complexity and potential for errors.
