Answer 1

You can use #function, #file, #line

Here is the implementation of log method in swift : https://github.com/InderKumarRathore/SwiftLog

Below is the snippet

public func debugLog(object: Any, functionName: String = #function, fileName: String = #file, lineNumber: Int = #line) {
  #if DEBUG
    let className = (fileName as NSString).lastPathComponent
    print("<\(className)> \(functionName) [#\(lineNumber)]| \(object)\n")
  #endif
}
