> There is very little IPC

I am not familiar with iOS internals, but does "very little IPC" mean "zero IPC"? Because if we are talking IPC in the context of bypassing permission checks, I imagine, 'very little' doesn't cut it?

I said "very little" because someone is probably going to be like "oh well you can have app A start allocating a bunch of memory and then app B gets a memory warning and this passes 1 bit of information"

Exactly: Some will use "IPC" as a stand in for side channels / memory safety, if it suits their agenda. I don't think it is a valid argument to make that the permission model is broken because "IPC".
