Hope this is the right place to ask for advice!
I work on an iOS project that has had a long-standing issue with incremental compile times. Making a change to the body of a private method results in a 90-120 second recompile. Using Instruments to see where the time is being spent pointed to the
XCBBuildService process, which spends the most time in the
ShellCommand::processMakefileDiscoveredDependencies function of llbuild (see attached graphic).
I'm a bit stuck on what to do with this information though. Could this be an issue in llbuild itself? Any advice would be appreciated!
