Logging Method signature using swift

I am trying to rewrite my logging class and I would like to know how to substitute PRETTY_FUNCTION or NSStringFromSelector(_cmd) in a swift file in order to track the method calls?

Solution

  • Check out a new library I've just published: https://github.com/DaveWoodCom/XCGLogger

    It's a debug logging library for Swift.

    The key to being able to use the #function macros, is to set them as default values to your logging function. The compiler will then fill them in using the expected values.

    func log(logMessage: String, functionName: String = #function) {
    print("\(functionName): \(logMessage)")
}

    Then just call:

    log("my message")

    And it works as expected giving you something like:

    whateverFunction(): my message
