Initializers declared in compiler protocol ExpressibleByBooleanLiteral shouldn't be called directly

The initializer in the ExpressibleByBooleanLiteral protocol should not be called directly because it is intended to be used by the Swift compiler to convert boolean literals into instances of types that conform to this protocol. This is part of Swift's design to ensure type safety and to provide a consistent way to handle literals across different types.
If you are interested in learning more about Swift's features and design, you might find the session A Swift Tour: Explore Swift’s features and design helpful, particularly the section on protocols. This session provides insights into how Swift uses protocols to build abstractions and how they work with both value and reference types.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
Explore Swift performance
Discover how Swift balances abstraction and performance. Learn what elements of performance to consider and how the Swift optimizer affects them. Explore the different features of Swift and how they’re implemented to further understand the tradeoffs available that can impact performance.
Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
