Running Existing Scripts on iOS Using XCUITest

Attention: Prior Silk Test Workbench versions used Instruments to automate iOS devices. With iOS 9.3, Apple has replaced the support for Instruments with support for the XCUITest framework, causing Silk Test Workbench to also no longer support Instruments. Because of this change, existing iOS test scripts might break when executed from the current version of Silk Test Workbench.
