The article showcases the author's attempt to decode and parse a legacy website that provides real-time train delays information for the Bulgarian railways using Swift. The author shares their experience using the national railways and the delays commonly experienced. They then discover a website called rovr.info that displays real-time train delay information, which is not available on the official website of the national railway company. Intrigued by this, the author decides to reverse engineer the website and parse the HTML structure to extract the necessary data. They find that the website uses a simple POST request to retrieve the data and identify the station IDs using a select element. The author successfully extracts the station IDs and demonstrates the process of decoding and parsing the website. This article is a great resource for developers interested in character encoding, reverse engineering, and web scraping using Swift.
