描述

Separate analyze and capture phase,i wonder to know how to reduce the capture phase time at iOS project ,i just want to analyze the changed files,but in capture phase Infer must run the translation file action,it translate the whole project files,can i just translate the changed files that i want to analyze?

below is what my command step 1.

infer capture -- xcodebuild -workspace demo.xcworkspace -scheme Debug -sdk iphonesimulator10.1 -configuration Debug build

step 2.

infer --fail-on-issue -a infer --changed-files-index ./index.txt -- analyze

In step 1 waste about 25 mins translate about 1900 files. Assuming that I just modified a file, but wasted 25 minutes during the capture phase, this situation was obviously unreasonable.

研究方向
Investigate the Infer codebase to understand how the capture phase works for iOS projects. Look at the source files related to capture, possibly in the `infer/src` directory. The issue requests a reactive capture that only processes changed files. Explore the possibility of integrating with tools like `fsmonitor` or using file modification timestamps to skip unchanged files. Also consider the existing ` changed files index` option and how it could be extended to the capture phase.
