#file, #line and #function are very common to debug features that are available in other languages like C++. I found it very useful to implement debug/logging manager. We can get the current file name, line number and function name from the #file, #line and #function respectively.

func debugPrint(_ info: Any) {
    // You can also use if debug to print output only in debug environment
    // #if DEBUG
    // Your print statement
    // #endif

    print("📂 \(#file) L[\(#line)] - \(#function) - \(info)")

func test() {
    debugPrint("Test function executed!")


// Output
// 📂 Debug.playground L[9] - debugPrint(_:) - Test function executed!
// 📂 Debug.playground L[9] - debugPrint(_:) - 10
