Summary
I've noticed that we occasionally get duplicate entries in merged sources of generated files. It often takes the form of:
public static var __mergedSources: [any ApolloAPI.SelectionSet.Type] { [
UserListItemFragment.self,
AvatarFragment.self,
FeedItemFragment.AsFollowRecommendationFeedItem.Followee.AsUser.self,
FeedItemFragment.AsFollowRecommendationFeedItem.Followee.AsUser.self
] }
Note that this has been a bug in some form since at least 1.2.0. In previous versions, this was a rare event. In 1.7.1, it's a certainty.
Version
1.7.1
Steps to reproduce the behavior
I've been able to reliably reproduce this by having both an in-line fragment on a member of a union type and a named fragment that relies on the same underlying type within the same selection set:
# Within a query response selection set
... on MyUnionType { # I don't know if this has to be a union type, but this seems to be the case that this is occurring in.
... on User {
# Whatever selections are needed
}
... UserListItemFragment
}
In this instance:
MyUnionType
is a union type that includesUser
UserListItemFragment
is a named fragment onUser
WORKAROUND:
Instead of structuring your selection as above, structure it like so:
...on MyUnionType {
... on User {
...UserListItemFragment
}
}
