When I import makeExecutableSchema I get the following error:

"message": "TypeError: _1.extractExtensionDefinitions is not a function. (In '_1.extractExtensionDefinitions(astDocument)', '_1.extractExtensionDefinitions' is undefined)",

I suspect the issue is here: https://github.com/apollographql/graphql-tools/blob/master/src/generate/buildSchemaFromTypeDefinitions.ts#L14

It seems that metro does not correctly resolve '.' to './index', changing the line works for me.
I also had to change these imports in different places (all in src/generate)

This should hopefully be fixed in https://www.npmjs.com/package/graphql-tools-fork

Should be fixed in graphql-tools@next, please let us know. Rolled into #1306 .
