• Try input by multiple regex expressions and emerge up the result what is the regex got fired

Basic usage

Firstly you should define the validation publisher within your @Published property

class FormViewModel: ObservableObject {
    
    @Published var email = ""
    public lazy var emailValidator: ValidationPublisher = {
        $email.validateWithRegex(
            regex: RegularPattern.email,
            error: "Not email",
            tableName: nil
        )
    }()
}

Excellent! And then, call the validate view modifier from your SwiftUI Input

TextField("Should email", text: $viewModel.email)
        .validate(for: viewModel.emailValidator)
