To declare a boolean number in Swift without using ExpressibleByBooleanLiteral, you can use an enum to represent boolean states. This approach allows you to define custom logic and associated values if needed. Here's a simple example:

enum BooleanState {
    case on
    case off
}

var state: BooleanState = .off

// Usage
state = .on

This method leverages Swift's powerful enum capabilities, allowing you to represent boolean-like states without directly using ExpressibleByBooleanLiteral. Enums in Swift can also have associated values, making them versatile for more complex scenarios.
