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.
