Instrumentation with source code on iOS

Instrument and Deploy your iOS app

First you have to instrument your iOS app.

Note icon


It’s recommended to fresh instrument your app for every new Ranorex release. For further information have a look at the section ⇢ Mobile Testing – Versioning.

This can be done by either following along with the video instructions or by following the textual description below.

Opening XCode project and add a new target

Adding the necessary libraries to the XCode project

Modifying linker flags and building a project.


Download the automation lib from the “Mobile Download Archive” on your Mac.

Note icon


The file size of Ranorex Automation Library is about 30 megabytes. This doesn’t automatically make your app 30 megabytes bigger, since it is a universal library and only the parts essential for your app will dynamically be added when compiling it.

Open the XCode project of your application under test.
In order to avoid shipping an instrumented app to your customers it is recommended to create a separate target for your app under test. You should select the project file and duplicate the existing target.


Rename the newly created target.
Note icon


As XCode does not automatically update all necessary files, you have to rename them manually. You will have to alter the target itself, the targets .plist file (in workspace as well as in Build Settings -> Packaging), the targets’ project name (Build Settings -> Packaging) and the schemes name (Product -> Manage Schemes).

Add the previously downloaded automation lib to your newly created target.

Add new file to project

Choose the lib file and specify the target, i.e. where the lib will be added

After doing this, the automation lib will be listed in the ‘Linked Binary With Libraries’ list in the ‘Build Phases’ pane of the test target.

Add the CFNetwork framework to the list.

Add CFNetwork.framework

Added automation lib and network framework

Note icon


With iOS 8.3 you additionally have to add the IOKit.framework.

In the ‘Build Settings’ pane of the test, add the switches ‘-ObjC -all_load’ to the option ‘Other Linker Flags’.

Set the switches ‘-ObjC’ and ‘-all_load’

After performing these steps, your project can be built using the newly created target and scheme for your iOS devices as well as simulators.

Note icon


If you see the debug output ‘RxAutomationEngine init‘ in the console pane, your app has been instrumented successfully.

Successfully instrumented app

  • Because the Ranorex automation lib uses non-public APIs, make sure that you do not submit a Ranorex instrumented app to the app store as your app might be rejected and you might be banned from submitting apps to the app store for a period of time.
  • To add your device via Wi-Fi, it’s necessary that the application under test is started on your iOS device or simulator.
  • The development provisioning profile should be used for testing your app and not the distribution provisioning profile.
  • To improve the object recognition of your app under test set the accessibility label attribute of your controls.
