Code sample with usage of special literals to create logger which captures file, function, line and column when used.

ThrowException.swift

public enum SomeError: ErrorType {
    case Foo
    case Bar
}

func willThrowException() throws {
    throw SomeError.Foo
}

public class Logger {
    static func log(msg: String, function: String = #function, file: String = #file, line: Int = #line, column: Int = #column) {
        print("Message: \(msg)")
        print("File: \(file); func: \(function); Line: \(line); Column: \(column)")
    }
}

func doSomething() {
    do {
        try willThrowException()
    } catch {
        Logger.log("Horrible error caught!")
    }
}
