TL;DR
This PR refactors the
EntitySelectionTreeinapollo-ios-codegen.What changed?
The conditions for merging selections were revisited. The use of
scopeConditionswas removed from the part of the code where the node's scope is checked if it is deferred. Instead, the condition to add merged inline fragments was moved under the child case, specifically when the child case is selections.How to test?
Unit tests pass
Why make this change?
This is a significant performance improvement as it removes an entire additional iteration through all the conditional scopes in the tree.
