Steps to reproduce

I was currently upgrading from 0.66.3 to 0.68.1 and did all the steps in the upgrade helper to do so. Afterwards the build is not working.

I managed to temporarily fix this by copying the files (which are symbolic links anyway) from ios/Pods/Headers/Private/Yoga/yoga to ios/Pods/Headers/Public/Yoga/yoga, started with BitUtils.h then ended up dragging a few more until it built successfully.

For me this started happening (maybe, still have to confirm but 99% sure) after I installed expo.

@cortinico @pedpess In the migration steps here, there is an info box saying exactly that! 😄

Aha! It’s indeed there @cipolleschi 😄 tks. This page should be marketed more because I was not even aware it existed. I guess most of us are using the RNUpgradeHelper and reading what are the warnings there that we should be aware of before migrating to newer versions
