Problems with Unified Logging, StaticString, CustomStringConvertible and description [duplicate]
This question already has an answer here:
Using os_log to log function arguments, or other dynamic data
1 answer
I'm wondering how I'm supposed to handle the following fairly common scenario using Unified Logging. Let's say I have an object of class Foo which I want to log. Foo implements the CustomStringConvertible protocol, so I can get a description of the object I can use in my logs:
class Foo: CustomStringConvertible {
var bar:Int = 1
var description: String {
return "<(type(of: self)): bar = (bar)>"
}
}
let myFoo = Foo()
If I call print(myFoo), I get a nice description of Foo. However, os_log(myFoo) won't work since description is not a StaticString. Is there a way to accomplish what I'm trying to do?

I'm having trouble understanding what part you find difficult, so here's a complete example and you can pick out of it whatever you need:
import UIKit
import os
let mylog = OSLog(subsystem: "com.neuburg.matt", category: "testing")
class Foo: CustomStringConvertible {
var bar:Int = 1
var description: String {
return "<(type(of: self)): bar = (bar)>"
}
}
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let foo = Foo()
os_log("%{public}@", log: mylog, String(describing:foo))
}
}
Prints:
[testing] <Foo: bar = 1>
...which I believe was the goal, no?
