Could not find button to launch Safari. Make sure you are using the latest version of SafariLauncher that appium is using

I want to do mobile browser automation on real iOS device using Appium. Here are the steps I have followed:
a) Git clone safari Launcher project and successfully installed safari launcher app into the i phone 6.
b) Copied the safari launcher.app file into the safari launcher folder in this path: Appium\Contents\Resources\node_modules\appium\build\SafariLauncher
c) Set ios_webkit_debug_proxy successfully and connected to my i phone.
d) When i run the appium; it connects to the device and open the safari launcher app on the device; but then the following error was thrown: “Failed to start an Appium session, err was: Error: Error. Could not find button to launch Safari. Make sure you are using the latest version of SafariLauncher that appium is using”.

Appium version: 1.4.13
X -code version: 7.3
i phone 6 ios version: 9.3
Enable UI Automation set to Yes in Developer mode.

Please let me know what is the resolution for this issue.
