When I #include <uvw.hpp> in any header file, xcode error: aligned deallocation function of type 'void (void *, std::align_val_t) noexcept' is only available on iOS 11 or newer

[guanghui1987]

1. error: aligned deallocation function of type 'void (void *, std::align_val_t) noexcept' is only available on iOS 11 or newer
2. xcode suggestion note: if you supply your own aligned allocation functions, use -faligned-allocation to silence this diagnostic
3. but I don't know to implement my own aligned allocation functions!
4. Please help me and thank you! Let's uvw run on more platforms!

I hope that build and run success in iOS 9 and 10 !

I don't even get what it means honestly. 😅 Have you investigated on the reasons of this error?

[skypjack]

The issue has been stuck for two weeks. I close it for inactivity. Feel free to continue the discussion here if needed.
