How to read environment variables in info.plist?

Question

I am setting a variable in the terminal

export VAR=1.0.0

And I have to read it from ~/.bash_profile into the info.plist like for example:

<key>CFBundleShortVersionString</key>
<string>VAR</string>

So like this I can do automated builds. Is there a way how to read the variables?

Answer 1

In the info.plist you reference the variable:

<key>CFBundleShortVersionString</key>
<string>$(VAR)</string>

Then when you build the project from the terminal you inject the value for the VAR:

xcodebuild build VAR=123 -project myProject.xcodeproj -target myTarget -sdk iphonesimulator

Or if the variable in set in the environment:

xcodebuild build VAR=${VAR} -project myProject.xcodeproj -target myTarget -sdk iphonesimulator

Please refer this link on SO,

PLIST Variables

$(PRODUCT_BUNDLE_IDENTIFIER) and $(PRODUCT_NAME) comes from Build Settings.

And ${EXECUTABLE_NAME} is concatenation of:

$EXECUTABLE_PREFIX, $PRODUCT_NAME and $EXECUTABLE_SUFFIX.

Hope this will help you.

I realised that I have not specified everything in my question so I have edited a bit. Maybe you know a way around. – Cauchy

The question was about environment variables in the build environment and not about referring to other variables or values inside the info.plist. – Whaler

Answer 3

You can use bundle to access the Info.plist.

 let v = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as? String

Accessing the info.plist is not related to the question. – Whaler
