Figuring out what is the reason for something being `undefined` could be quite difficult because the reasons can vary. To check whether metadata filtering is to blame or not you should examine metadata generator's verbose logs after a successful build:
 
 - On iOS they are located in `platforms/ios/build/<configuration>-<platform>/metadata-generation-stderr-<arch>.txt` (e.g. `platforms/ios/build/Debug-iphonesimulator/metadata-generation-stderr-x86_64.txt`);

 For each global symbol that is discovered by the generator, there should be a line providing information whether it was included in the metadata or not, and which rules or what exception caused this. Examples:
