I have only one large project write with swift 3.2 and use Xcode 9.1 to open it. But I can't use function "Jump to definition" of Xcode, it only show question mark (?). The other project can "Jump to definition". How can I fix it? Very thanks.

Force Quit Xcode -> Start Xcode -> Clean Build Folder
Let the indexing finish and files getting processed.
Run the build again.
