Its a custodial risk.

But I think the real question is Why are people so adverse to just ditching apple? For years they've made their intent clear by complying with draconian chinese regulation and removing other bitcoin related apps (mostly wallets) so why support this? It seems extremely asinine to want to still support a company thats bent on curtailing what you can do with their device and restricting your freedom. Vote with your dollars and move on.

Im not saying google is better at all, they are not. But at least with most android devices you have the option to use other software and you dont habe to go as far instslling a new operating system. A few button pushes and boom good to go.
