I have no idea what went wrong, we were able to install the application on the iOS device before, but I changed my mac, and the error started appearing.
So I have no problems with running appium and the inspector over simulators using the .app file. The issue is only with trying to have appium run over real devices. I tried with a ipa that is of ad-hoc build, and .app files that were done with developer provisioning.
Im able to install the app over X-Code, but if I Run the same over appium, it gives either a fruitstrap crash error, and if the app is already installed on to the device and appium is run, it gives a “error: Failed to start an Appium session, err was: Error: Instruments crashed on startup”. and the app starts up and closes instantly.
I have read almost all stack overflow pages on the error, and none of the solutions seem to help me solve this. 
Error if app is already installed on the device :-
