It's about 50K lines of code all told (using simple find | wc -l ) all library code used (except for language and posix standard libraries) is included in the repo. "What is the build cycle time for your C++ code?" Depending on the machine, 10-20 seconds "Does it kill xcode's indexer?" Not at all. "Does it get included into the iOS project?" Yes it does. We have it as a git sub repo and a sub project in XCode. Both those things allow us great freedom in independent development, testing, release versioning etc. Of course there are also make files for independent build/test cycles on linux etc. Another bonus of having it as a first class XCode project, clang Analyze tool does beautiful static analysis. What a godsend that is.
