xcode/ native iOS Object Reco without unity

Hey,

i managed to get a big party for my project working with unity and vuforia. Unfortunately I ended up connecting my app with a database (Firebase) which didnt work at the end. So I again started to think about setting it all up with xoce, eventho it seems much more complicated. Furthermore in the Object Recognition Guide I can only find Android and Unity guides. Is there no chance to get object recognition working in Xcode, so without going via unity to an iOS app? Or maybe someone knows how to get a firebase database which is setup in unity, working after compiling in the iOS app? I pretty much need to display some realtime data in my AR app. The data need to get received from the firebase database.

To get firebase running with xcode in iOS is no big deal, just the vuforia seems to not easy to get running. And I really need target recognition over image recognition. Thanks so much for your answer, idead, solution or whatsoever. I just highly appreciate any response
