If you need a way to communicate wirelessly with Apple devices in close proximity to each other, in a blazing fast way, and you're quite comfortable with Swift, this course is likely a good match for you. SwiftUI and Combine knowledge will be helpful: they're both used in this course, but are not essential for employing Multipeer Connectivity.
