Error Handling 🕵️♂️
Each property that is declared with the @Validated
attribute can make use of advanced functions and properties from the Validated
Property Wrapper itself via the $
notation prefix.
Beside doing a simple nil
check on your @Validated
property to ensure if the value is valid or not you can access the validatedValue
or validationError
property to retrieve the ValidationError
or the valid value.
@Validated(.nonEmpty)
var username: String?
// Switch on `validatedValue`
switch $username.validatedValue {
case .success(let value):
// Value is valid ✅
break
case .failure(let validationError):
// Value is invalid ⛔️
break
}
// Or unwrap the `validationError`
if let validationError = $username.validationError {
// Value is invalid ⛔️
} else {
// Value is valid ✅
}
