The .ipa file should not be one that you downloaded from iTunes. Such files have DRM restrictions which will not allow instrumenting the application. The application should be a production build version without DRM restrictions.
To illustrate the process of instrumenting iOS applications, we provide two non-instrumented demo applications for iOS devices which can be found on the installation folder under .../bin/ipas:
(Links can be opened only from iOS devices)
EriBankO.ipa (bundle identifier: com.experitest.ExperiBankO)
BrowserO.ipa (bundle identifier: com.experitest.BrowserO)
Also on the same folder are copies of the same already after instrumentation. They will automatically be available on the Application manager.
Note: You can use distribution profiles for the instrumentation process.
Step 1: On Silk Mobile UI, Choose Help Tab and select iOS Sign Configuration option.
Step 2: On the iOS Sign Configuration you can configure the needed files for the instrumentation.
Step 3: If you don't have an apple account, you can use a DEF file. You should receive by email a DEF file (Device Enablement File).
Step 4: With this file complete the iOS Sign Configuration process as depict in the page.
Step 5: Import the .IPA file (should be available on your local disk) via the Application manager.
Step 6: On the Application manager click the Install button. It will install the application on the device. During the installation process the application will also be instrumented.
Step 7: Once installation is over user will be promoted with a message box to launch the application.
Step 8: Application will be launched instrumented (Screen of the device with instrumented app on object spy mode).
