I can't replicate that behavior.

This doesn't work:

// Roland's protocol must be marked @objc since it has optional requirements.

@objc public protocol PublicProtocol {
	func someFunction()
	// ...
}

private class SomeClass: NSObject, PublicProtocol {
	func someFunction() {
		// implementation
	}
}

Type 'SomeClass' does not conform to protocol 'PublicProtocol'
Fix-it: Candidate is not '@objc', but protocol requires it
