I think we can safely say that Reddit content is organized in a way that should be conducive to deep linking (each post and comment thread has a unique and permanent URL). Their deep links generally work well for me though, unlike some other apps. I once had to implement deep links for a React Native app and, while I’m by no means a great mobile dev there were plenty of thorny bits. For example, I think iOS doesn’t open a deep link in app if you type the url directly into the address bar. It will only open in the app if the user taps a link. Another complexity is making sure a deep link opens in the app for app users and opens the App Store for other users. iOS also has two different systems for deep linking, custom protocols (eg myapp://) and universal links (a server side manifest that you register with Apple). These each have their pros and cons. To be sure, those should be solvable problems for a company with even a fraction of Reddit’s resources.
