The validation system checks required fields, validates data formats, and provides detailed feedback about validation status.

How Required Field Validation Works

Joyfill automatically validates required fields based on:
  • Field requirement: Fields marked as required = true
  • Field visibility: Hidden fields are always filtered out of the validation output
  • Field values: Required fields must have non-empty values to be valid
Basic Usage 
let documentEditor = DocumentEditor(document: document)

// Validate all fields
let validationResult = documentEditor.validate()

if validationResult.status == .valid {
    print("Form is complete and valid")
    // Proceed with submission
} else {
    print("Form has validation errors")
    // Show errors to user
}
Key Points
  • Call validate() before form submission
  • Check status for overall validation result
  • Use fieldValidities to get specific field errors
  • Required fields must have non-empty values
  • Hidden fields are always filtered out of the validation output (conditional logic and hiddenViews)
  • Page hidden: all of its fields are valid
  • Table/Collection: validate their required columns per row. Each FieldValidity includes rowValidities with row-level and cell-level results (RowValidity and CellValidity)
  • Non-required table/collection fields still validate rows against required columns
  • Navigate to invalid fields: use fieldValidity.pageId and fieldValidity.fieldPositionId with goto() to navigate directly to invalid fields
