LoggerHelper

A simple Swift logging library for macOS apps. Log messages at different levels (info, warning, debug, error), control logging globally, and customize subsystem and category for each message.

• Four log levels: info, warning, debug, error
• Enable or disable all logging with one flag
• Default subsystem is your app’s bundle identifier (overrideable)
• Default category is "General" (overrideable)
• Each log entry includes file name, line number, and function name

• macOS 10.15 or later
• Swift 5.5 or later

1. In Xcode, choose File ▸ Add Packages…
2. Enter the URL of this repository:

   https://github.com/YourUserName/LoggerHelper.git
   

3. Select the version (for example, Up to Next Major 1.0.0) and add it to your app target.

1. Enable logging early in your app (e.g. in AppDelegate):

   import LoggerHelper
   
   @main
   class AppDelegate: NSObject, NSApplicationDelegate {
     func applicationDidFinishLaunching(_ notification: Notification) {
       // Turn logging on or off as needed
       #if DEBUG
       LoggerHelper.loggingEnabled = true
       #else
       LoggerHelper.loggingEnabled = false
       #endif
   
       LoggerHelper.info("App did finish launching")
     }
   }

2. Log with defaults:

   LoggerHelper.info("Hello, world!")

   • Uses Bundle.main.bundleIdentifier as subsystem
   • Uses "General" as category

3. Log with custom subsystem or category:

   LoggerHelper.debug(
     "User tapped button",
     subsystem: "com.mycompany.mytool",
     category: "UI"
   )

4. Other levels:

   LoggerHelper.warning("Low disk space")
   LoggerHelper.error("Failed to load data")
