How to upload a file to an iOS app?

Question

iOS

Hello!
Please tell me where to dig, where to find manuals on this issue:
I am writing my application, for its operation you will need a certain text file, for example, generated with a certain period of time on a working PC, from which data will be read. This text file must somehow be pushed into the application, the question is how exactly :)
Thanks in advance for your help!

where to dig

These are networks, the easiest way is HTTP, an important point is how to organize communication, if the PC and the phone are on the same local network, then it’s not a problem for the PC to make the server, the application the client, but if they are connected only by the Internet, then either the PC must have an external static IP, or you will need an external server, and the PC and the application in this case will be clients.
Rather, one should ask "for how much, in tens of thousands of rubles .... not Belarusian." Or do it yourself, using what is.
