Intercept NFC-Events with Swift App

Hi, I'm writing an app in Swift and it needs to work with NFC. I've already seen dozens of tutorials for implementing a NFC-reader in your app, but I need my app to intercept every NFC-Event, so whenever a Tag is read even tough the app might not be active at the moment. The best-case scenario would be, that my app then checks if the data is relevant for it's use and if not "frees" the event and lets the system handle it. Does anybody have some advice on how to implement such a behavior?
