so that I can use my bitcoin core wallet on my iPhone
For consideration: if you use the same wallet on multiple devices, you increase the risk of getting it compromised. In general, I consider phones to be untrusted devices, and only add fund mobile wallets with small amounts. If you're expecting to get a substantial amount of Bitcoin, it's safer to store the majority in a safer way.
Cannot stress this enough if there is a 'real' amount of funds involved. If you are talking about going out to dinner money that's one thing. But treat any funds on your phone as cash and be prepared to loose it at any time. Not to mention, if something does happen, now you have to figure out is it the desktop PC or the phone that caused the funds loss.
Who had access to what and when, and so on.
Better off keeping them separate.
