问题 I'm decoding several gigabytes of JSON encoded data like this let decoder = JSONDecoder() let table = try decoder.decode([LogRow].self, from: content!) where content is plain text. Now, this operation can take several minutes, depending on the size of content , and I'd like to show some kind of progress.
