Optional+Unwrap.swift

import Foundation

extension Optional where Wrapped == String {
    /// Return true if the string value is not nil and not empty string
    var exists: Bool {
        switch self {
        case .none:
            return false
        case .some(let string):
            return !string.isEmpty
        }
    }
    
    func unwrap(_ defaultValue: String = "") -> String {
        if self.exists {
            return self ?? defaultValue
        } else {
            return defaultValue
        }
    }
}

extension Optional where Wrapped == Bool {
    func unwrap(_ defaultValue: Bool = false) -> Bool {
        switch self {
        case .none:
            return defaultValue
        case .some(let bool):
            return bool
        }
    }
