I liked the approach of builders for solving complex logic and specifically the block-based builder design.

I have a single concern that if for simple data models we are using builders, which essentially is an additional component, can’t we have the same flexibility with structs and a default value nil for optionals.

struct OptionDetailDataStruct: Equatable {
let isExpired: Bool
let expiryDate: String?
let cardNumber: String?
let formattedNumber: String?
let phoneNumber: String?
init(isExpired: Bool, expiryDate: String? = nil, cardNumber: String? = nil, formattedNumber: String? = nil, phoneNumber: String? = nil) {
self.isExpired = isExpired
self.expiryDate = expiryDate
self.cardNumber = cardNumber
self.formattedNumber = formattedNumber
self.phoneNumber = phoneNumber
}
}
