iOS extensions with multiple targets
Solution 1:
To share one widget with others targets, you only need to add widget.appex target
to Embedded Binaries for every parent target in General configuration tab
Then you'll get Embed App Extensions area at Build Phases automatically
Solution 2:
This is my setup: I have 3 targets (production, staging, local) and an extension target that I don't want to duplicate 3 times.
Just to clarify Neo Chen's answer, edit each of your parent targets' schemes:
Build > Pre-actions > New Run Script Action > Provide build settings from (parent scheme).
Paste this for each extension:
#!/bin/bash
buildID=${PRODUCT_BUNDLE_IDENTIFIER}
extId="notification-service"
/usr/libexec/PlistBuddy -c "Set :CFBundleIdentifier $buildID.$extId" "${SRCROOT}/${extId}/Info.plist"
Seems to work on first build.
Solution 3:
It seems like you should be able to just duplicate the Extension target with its own Info.plist, but not anything else.
However, when you create an Extension, Xcode adds "Embed App Extensions" to the Build Phases of the app's target, as seen below, and there's no UI to do that yet.
Still, you can create the extension for the second target, then delete all the files except the .plist, and fix what needs to be fixed. Here's a step-by-step:
- Create "Extension 1" for "Target 1"
- Create "Extension 2" for "Target 2"
- Delete all files created for "Extension 2", except its Info.plist
- Make the "Build Phases" for "Extension 2" target the same as the build phases for "Extension 1". Usually that's adding the necessary .m files to the "Compile Sources" phase, and resources to the "Copy Bundle Resources" phase
