Swift is great for that:

    do {
       let file = try FileManager.create(…)
    } catch {
       logger.error("Failed creating file", metadata: ["error": "\(error)"])
    }

Note the try is not actual CPU exceptions, but mostly syntax sugar.

You can opt-out of the error handling, but it’s frowned upon, and explicit:

    let file = try? FileManager.create(…)

or

    let file = try! FileManager.create(…)

The former returning an optional file if there is an error, and the latter crashing in case of an error.
