The proxy pattern is used to provide a surrogate or placeholder object, which references an underlying object. Virtual proxy is used for loading object on demand.

Example

protocol HEVSuitMedicalAid {
    func administerMorphine() -> String
}

final class HEVSuit: HEVSuitMedicalAid {
    func administerMorphine() -> String {
        return "Morphine administered."
    }
}

final class HEVSuitHumanInterface: HEVSuitMedicalAid {
    lazy private var physicalSuit: HEVSuit = HEVSuit()
    func administerMorphine() -> String {
        return physicalSuit.administerMorphine()
    }
}

Usage

let humanInterface = HEVSuitHumanInterface()
humanInterface.administerMorphine()

Contacts
I have a clear focus on time-to-market and don't prioritize technical debt. And I took part in the Pre-Sale/RFX activity as a System Architect, assessment efforts for Mobile (iOS-Swift, Android-Kotlin), Frontend (React-TypeScript) and Backend (NodeJS-.NET-PHP-Kafka-SQL-NoSQL). And I also formed the work of Pre-Sale as a CTO from Opportunity to Proposal via knowledge transfer to Successful Delivery.
