We tried to adopt OSLog in past years, but it was really cumbersome to retrieve the logs from customers. Doing a sysdiagnose is a really cumbersome task for most non-technical users to perform. Additionally they contain WAY more information than we need and are generally very large. This is true for macOS and iOS apps. Are there any new facilities for retrieving just the logs for a given subsystem that we could trigger with code, for instance in a help menu?

In our app, we need to provide a feature for user to send application logs to us in case they run into unexpected errors. If we use OSLog feature to log our app's error/warning state, is there a way to programmatically to collect our app log from within our app so that we can provide a feature for user to send us the archived log files within our app?

It seems that OSLogStore allows accessing logs on both macOS (AppKit), macOS (Catalyst) and iOS. Currently it works on both mac variants, but it fails with an entitlement error on iOS. Sample Code: func getLogEntries() throws -> [OSLogEntryLog] { // FB8269189: OSLogStore does not work iOS. let logStore = try OSLogStore(scope: .currentProcessIdentifier) let oneHourAgo = logStore.position(date: Date().addingTimeInterval(-3600)) #if os(macOS) let allEntries = try logStore.getEntries(at: oneHourAgo) #else // FB8518476: The Swift shims for for the entries enumerator are missing. let allEntries = try Array(logStore.__entriesEnumerator(position: oneHourAgo, predicate: nil)) #endif // FB8518539: Using NSPredicate to filter the subsystem doesn't seem to work. return allEntries .compactMap { $0 as? OSLogEntryLog } .filter { $0.subsystem == subsystem } } When running on the iOS Simulator, the following error is thrown: Error Domain=OSLogErrorDomain Code=9 Client lacks entitlement to perform operation UserInfo={NSLoca

How to extract the logs generated using logs api from device so I can send to a remote server? Are APIs available to read and compress log data from device?

The new logging system looks nice, but the video didn't discuss how to get those logs from production devices. It only covered getting them during testing. If a customer contacts support from inside my app, I need to get a copy of the logs from that app/user. I currently am writing my logs to a text file, and then attaching that when they contact support. I realize that isn't ideal from a performance perspective. import os let logger = Logger(subsystem: com.example.Fruta, category: giftcards) logger.log(Started a task)

If an instance of Logger is created with the same subsystem and identifier in another part of the app, will they conflict in Bad Ways? 2 Should a global Logger be passed from parent objects to child objects (like a dependency injection), or is creating new instances of Logger for many objects ok?

When trying to add the example code from WWDC 2020 to my project I get dyld: lazy symbol binding failed: Symbol not found: _$s2os6LoggerVMa ... Expected in: /usr/lib/swift/libswiftos.dylib @available(OSX 10.16, *) let logger = Logger(subsystem: com.example.Fruta, category: giftcards) @available(OSX 10.16, *) @NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate { var window: NSWindow! func applicationDidFinishLaunching(_ aNotification: Notification) { logger.log(logged Message)

How can a Customer send me his Logs without connecting to a Mac?
