Swift Binding Fixer

Instructions

Fix "cannot find '$viewModel'" errors:

1. Find the error:

   grep "cannot find '\$viewModel'" build_output.txt
   

2. Read the view file:

   • Check if viewModel is @Observable type
   • Look for @State var viewModel or var viewModel
   • Find all $viewModel.property usages

3. Apply fix:

   // BEFORE
   @State var viewModel: MyViewModel
   // OR
   var viewModel: MyViewModel
   
   // AFTER (if using $viewModel)
   @Bindable var viewModel: MyViewModel
   

4. Common Leavn patterns:

   • HomeViewModel: Use @Bindable for sheet bindings
   • CommunityViewModel: Use @Bindable for showCreate* bindings
   • SettingsViewModel: Use @Bindable for alert bindings
   • SermonAIView: Use @Bindable for showing* bindings

Use this skill when: $viewModel errors, @Observable binding issues, sheet presentation errors
