How to use App center environment variables in iOS project

Question

I have tried a few things, but I can't get the variables to stick, probably because I am not used to writing Scripts.

The documentation from Appcenter : https://learn.microsoft.com/en-us/appcenter/build/custom/variables/ It says I can only access the environment variables from app center in the build script..

1. I have tried creating a Run Script from Build phases, but no variables is saved no matter what. How do I save an environment variable ? I have tried, export ENVIRONMENT_TEST="abc", but I cant see it afterwards using

   let environments = ProcessInfo.processInfo.environment["ENVIRONMENT_TEST"]

2. I found a similar issue: Using Microsoft App Center environment variables in iOS

here the solution is to save the environment variable $ENVIRONMENT_VARIBLE to a file and read from it later. So now im trying to save to a new plist file. This works locally, but not from a device. I believe its because the path is different. I use:

plutil -replace somekey -string somevalue1 ${SOURCE_ROOT}/AppName/AppcenterValues.plist

Any ideas for this ?

Answer 1

the predefined variables are different, instead of SOURCE_ROOT use APPCENTER_SOURCE_DIRECTORY. You script will end up something like this:

plutil -replace somekey -string somevalue1 $APPCENTER_SOURCE_DIRECTORY/AppName/AppcenterValues.plist

You can find more examples on the official AppCenter github repository in following link:
