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