1.17.0

New

• Add suffix to schema type filenames (#2598): When fragments were named the same as schema types code generation would produce two files with the same name, but at different paths, for each respective type. This would cause a build error in Xcode. There is a new codegen configuration option (appendSchemaTypeFilenameSuffix) to add a suffix to schema generated filenames and prevent the build error. See PR #580.
• Specify caching fields with typePolicy directive (#554): The @typePolicy directive lets you specify an object's cache ID using key fields of the response object. See the documentation for full details. Thank you to @x-sheep for the contribution.
• Emit Identifiable conformance on SelectionSet (#584): If the @typePolicy of a type uses a keyField of id the selection set will emit conformance to Swifts Identifiable protocol. Thank you to @x-sheep for the contribution.

Improvement

• Improved performance of code generation on operations with many nested fragments (#3434): When fragment field merging is disabled the fragment selection trees are no longer merged into the EntitySelectionSet while building operations. See PR #571.

Fixed

• Defer metadata extension (#3505): Metadata extensions for deferred selection sets were incorrectly generated inside the namespace extension for embeddedInTarget and other module types. See PR #581.
• DataDict initialization of deferredFragments for named fragments (#587): When deferred fragments are named fragments the deferred type should be the fragment generated definition name.
