How to set FBPLISTAppIDKey and FBPLISTAppSecretKey with FBTestSession

Question

I am getting an exception using FBTestSession when using FBTestSession *fbSession = [FBTestSession sessionWithSharedUserWithPermissions:@[@"email"]];

If you look at the code below you can see Facebook decided to load app settings from NSProcessInfo: https://github.com/facebook/facebook-ios-sdk/blob/master/src/FBTestSession.m#L506

NSDictionary *environment = [[NSProcessInfo processInfo] environment];
    NSString *appID = [environment objectForKey:FBPLISTAppIDKey];
    NSString *appSecret = [environment objectForKey:FBPLISTAppSecretKey];
    if (!appID || !appSecret || appID.length == 0 || appSecret.length == 0) {
        [[NSException exceptionWithName:FBInvalidOperationException
                                 reason:
          @"FBTestSession: Missing App ID or Secret; ensure that you have an .xcconfig file at:\n"
          @"\t${REPO_ROOT}/src/tests/TestAppIdAndSecret.xcconfig\n"
          @"containing your unit-testing Facebook Application's ID and Secret in this format:\n"
          @"\tIOS_SDK_TEST_APP_ID = // your app ID, e.g.: 1234567890\n"
          @"\tIOS_SDK_TEST_APP_SECRET = // your app secret, e.g.: 1234567890abcdef\n"
          @"To create a Facebook AppID, visit https://developers.facebook.com/apps"
                               userInfo:nil]
         raise];
    }

The problem is, I'm not able to figure out how to set FBPLISTAppIDKey and FBPLISTAppSecretKey correctly and there is no other setter to use.

You need to add them as environment variables in your scheme.

{scheme} >> Run >> Arguments (Tab) >> add the test app id and test app secret.
