I have the same wheels, 18 x 10.5 + 34 using 295/35/18 squared but I am on coilovers and other arms. No rubbing. You can fit this setup with height adjustable springs like HKS and aftermarket tophats for more camber. Tire choice will also affect how they fit as some run slightly wider than...
I'd sometimes have issues with the CarPlay crashing and not reconnecting. To fix that I'd have to delete & reconnect it using Bluetooth. Might be worth giving a try but hard to say if it will fix your problem.
It works. The car pictured is running the EXACT set up (wheels, tires, HAS) you're describing. He later swapped in adjustable top hats after as theres little camber adjustment without them.
Hope this helps.
