How to use libtorch on ios11

I found that the libtorch support ios 12 at least from this linkhttps://github.com/pytorch/pytorch/blob/master/ios/LibTorch.podspec. How can I use libtorch on iso11? Whether the way of building from the source is feasible?

Build from source for iOS is possible, check iOS | PyTorch

Regarding iOS 11, maybe worth a shot, I’m not sure
