+To run iOS version of client cocoapods pod needs to be compiled and installed to XCode project 
+located in `ios-app`. The easiest way to compile and link all ios targets is to run

+./gradlew linkPodReleaseFrameworkIosFat linkPodDebugFrameworkIosFat
+```
+
+from the root directory of project and then 
+
+```shell
+./gradlew podInstall
+```
+
+to install the compiled resources to XCode.

+`ios-app/Configuration/Config.xcconfig` to your own and then open XCode workspace available 
+in `ios-app`.
