Consider this snippet:
let log = Logger(subsystem: "com.example.apple-samplecode.Test738648", category: "app")
@IBAction
private func testAction(_ sender: Any) {
log.log("Hello Cruel World! pid: \(getpid()), proc: \(ProcessInfo.processInfo.processName)")
}
By default the proc value is private and thus not recorded. This is true in both Xcode 15 and Console.
The easiest way to opt in to private data recording is the OSLogPreferences mechanism discussed in Recording Private Data in the System Log. For example, if I add this to my Info.plist:
<key>OSLogPreferences</key>
<dict>
<key>com.example.apple-samplecode.Test738648</key>
<dict>
<key>app</key>
<dict>
<key>Enable-Private-Data</key>
<true/>
</dict>
</dict>
</dict>
I see the private data in both places. I’m testing with Xcode 15.0 on macOS 13.5.2.
The main problem with this approach is that it’s hard to conditionalise out for your release builds. There are a couple of ways you could do that:
-
Customise the Info.plist File build setting to point to a different Info.plist file.
-
Change tack, and use a configuration profile. I’ve pasted an example of such a profile below.
Personally, I’m a fan of the configuration profile approach because it means there’s no chance of you shipping a build that accidentally records private data.
