I have a suggestion:

	if #isDebugBuild {

That would allow you to capture a caller's debug setting, just as you can capture their file and line number:

	class Logger {
		enum LogLevel {
			case fatal, error, warn, info, debug, trace, off
		init(logLevel: LogLevel) {
		convenience init(debug: Bool = #isDebugBuild) {
			self.init(logLevel: debug ? .debug : .warn)
