 ### Changed
 - Targets in the generated project now follow the declaration order from the source spec (Xcode sidebar, `xcodebuild -list` output). Previously they were always sorted alphabetically. Applies to both YAML and JSON specs. Declaration order is now also preserved for targets whose `platform`/`name` come from a target template and for targets whose key is a `${VARIABLE}`. #1619 @mirkokg
 
+### Fixed
+- Preserve nested target attributes such as `SystemCapabilities` as native PBX dictionaries #1643 @TblKBA
+
 ### Internal
 - Update to XcodeProj 9.14.0 #1629 @philprime
