问题
In our project we derive our release version from git tag etc then write it to the built folder's Info.plist with a shell script like:
GIT_RELEASE_VERSION=$(some git command)
defaults write "${BUILT_PRODUCTS_DIR}/${INFOPLIST_PATH%.*}" "CFBundleShortVersionString" "${GIT_RELEASE_VERSION#*v}"
This has worked well for all past Xcode versions, but in Xcode 10's New Build System this failed to actually update the CFBundleShortVersionString in the info.list file. The value is correctly updated with Xcode 10's Legacy Build System though.
I added some echos to the script and compared the build log on New and Legacy systems and cannot see any difference:
echo "git release version:" ${GIT_RELEASE_VERSION}
echo "info path:" ${BUILT_PRODUCTS_DIR}/${INFOPLIST_PATH%.*}
echo "grv:" "${GIT_RELEASE_VERSION#*v}"
Not sure if anyone out there encountered similar issues with the New Build System?
回答1:
It seems like the problem is that sometimes your Run Script Phase will execute before Xcode creates the Info.plist. If you’d like to ensure that your script phase runs after a specific step, you need use the inputs to mark your dependencies.
For instance, adding:
$(TARGET_BUILD_DIR)/$(INFOPLIST_PATH)
As an input to your script phase should enforce the ordering you are looking for: Xcode will create the Info.plist and sometime after, your script will execute and modify the Info.plist.

Same issue here... one work-around is to clean and then perform full-build.
The new build system in Xcode 10 runs the Process Info.plist step differently in full and incremental builds:
- Full-build: after processing assets, before linking storyboards (link step)
- Incremental: after embedding frameworks, before signing.
The actual problem is the script that runs as a build step & updates the processed Info.plist file needs to always run after the the file is processed but before signing.

Similar to the answers above (can't comment yet) but slightly changed.
Scripts input files:
$(PROJECT_DIR)/$(INFOPLIST_FILE)
$(TARGET_BUILD_DIR)/$(INFOPLIST_PATH)
Output files:
$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)
I created a gist with a script I use to set the bundle version and some extra info like tag, date, branch.

(Xcode 11.2)
- In the New Build System, any custom build steps will run before the New Build System's
Process .../Info.pliststep:
- To run a shell script after Xcode finishes building, you can add it to your scheme(s) as a build post-action:
Product > Scheme > Edit Scheme... > Build > Post-actions
If you're going to reference any build system environment variables (e.g.
BUILT_PRODUCTS_DIRorINFOPLIST_PATH), make sure you change the Provide build settings from selection.Add your shell script, but remember that if you edit any file in the app bundle (i.e.
Info.plist), you'll need to re-sign the app. Add this to your post build step:
export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate
/usr/bin/codesign --force --sign - --entitlements "${TARGET_TEMP_DIR}/${FULL_PRODUCT_NAME}.xcent" --timestamp=none "${CODESIGNING_FOLDER_PATH}"
