In our latest Ask a Dev video, iOS engineer Dan Murrell discusses the limitations of beacons, and some of the issues developers might encounter while working with this new technology. Beacons can pinpoint the location of a device, and then exchange data with that device. Beacons can sync with certain apps to enhance many digital experiences — improving the way we shop at stores or helping us to find movie showtimes on the go. There's even a beacon beer crawl. However, as with all new technologies, it does have its limitations and weaknesses. "One of the best ways to explore the full potential of a new technology is to find its limitations," says Murrell. "If we want to take advantage of all its features, we need to understand its problems and its pitfalls too".
