Pulse is a logging system with structured persistent storage.

PulseUI allows you to quickly preview logs in your iOS or tvOS apps. Share logs, and use Pulse macOS app to search and filter them. PulseUI is available for GitHub sponsors.

Use log() function to send logs.

log("Your message")
log(level: .fatal, system: .auth, "Configuration is missing")

/// Logs the message in the console (if enabled) and saves it persistently.
///
/// - note: Logger automatically captures stack traces for .fatal logs.
///
public func log(level: Logger.Level = .debug,
                system: Logger.System = .default,
                category: Logger.Category = .default,
                _ text: @autoclosure () -> String)

All of the logged messages are stored persistently using Core Data. You get full access to all of the recorded messages at any time using Logger.Store.

let message = try logger.store.allMessage()

// NSPersistentStoreContainer
let container = logger.store.container
