iOS build is failing #66
Description
On one hand, I suspect React Native 0.61.5 is not compatible with Xcode 12+. React Native 0.62.0 works fine. On the other hand, the app we developed for one of our clients depends on 0.61.5 and builds successfully with Xcode 12.1. However, in the latter we're using Xcode's legacy build system.
We shouldn't use the legacy build system because it has been deprecated since the beta release of Xcode 12. We must upgrade React Native as soon as possible, ideally to the latest stable version. See #65.
