Automatic UI Generation Using Macros

A Swift macro package that provides the @FormBuilder macro for automatic, type-safe UI generation of SwiftUI forms based on your data model struct’s properties.

Features

• Automatic Form Generation:
  Annotate your SwiftUI view struct with @FormBuilder and automatically generate a complete body with properly bound SwiftUI controls for each property.
• Type Inference:
  • String → TextField
  • Bool → Toggle
  • Date → DatePicker, etc.
• Reduces Boilerplate:
  Focus on your data model, not repetitive form code.
• Swift 5.9+ / Xcode 15+ Support:
  Built using Swift's macro system and SwiftSyntax.

Usage

1. Import the Macro Package:

   import FormBuilderMacros
   

2. Use the Macro in Your SwiftUI View:

   @FormBuilder
   struct EditContact: View {
       @State var name: String
       @State var number: String
       @State var isFavourite: Bool
   }
   

   The macro automatically generates this form's body with a TextField and Toggle bound to the properties.
