this is pretty neat. I'm building a cross-platform project with yew and this should make things much smoother

I am, however, having trouble getting the examples to work. some issue with installing `aarch64-apple-ios` using `stable-aarch64-apple-darwin`

    error: failed to install component: 'rust-std-aarch64-apple-ios',
    detected conflict: 'lib/rustlib/aarch64-apple-ios/lib/libaddr2line-8a8c95c7e51dcc3f.rlib'

my rust-foo is limited, so I'll keep digging, but if anyone knows of a solution, I'm all ears and deeply grateful
