Answer 1

Perhaps you have this line in your Podfile config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'

Until they fix it, you can remove it

Answer 2

The podspec of MaterialComponents is missing a dependency. Because the build order can vary a bit with parallel builds in Xcode it will not always occur.

The fix is adding MotionInterchange as dependency of ActivityIndicator:

diff --git a/MaterialComponents.podspec b/MaterialComponents.podspec
index d37749ea9..931c25fed 100644
--- a/MaterialComponents.podspec
+++ b/MaterialComponents.podspec

Answer 3

This is just a quick solution to avoid to modify the library .podspec

Maybe not the most recommendend option but it could save some time while considering moving from Material Component to a better solution.

In the podfile of your project, include:

pod 'MotionInterchange'
