When a generic type is conditionally conforming to a protocol, the conformance is applied only if the generic type's parameters meet specific requirements specified by the conditional conformance.
Here's an example to illustrate conditional conformance in Swift:
The extension MyStruct: Printable where T: CustomStringConvertible provides a conditional conformance to the Printable protocol. It specifies that MyStruct conforms to Printable only when the generic type T conforms to the CustomStringConvertible protocol.
With this conditional conformance, if we create an instance of MyStruct with a type that conforms to CustomStringConvertible, we can call the printDescription() method on it:
Conditional conformance is a powerful feature that enables more expressive and flexible code, allowing protocols to be applied to a wider range of types based on certain requirements.
