Well apple will likely not support bitcoin because as a cooperation it have the intention of creating their own digital currency and at that they will always fight against the growth of the entire bitcoin network, but I know that with time apple will realize the importance of bitcoin and how it superior to all other form of payment system is.
I think the optimization of payments in cryptocurrency (in Bitcoin in particular) is a matter of time and growth in the importance of the crypto market itself. As long as its capitalization is now treading around 200 billion, we will not see implementation of the Apple-based product.
