title: How to get an iOS app build for appium testing?
body: <p>I wanted to setup iOS testing on simulator on my MacBook-pro. Im using appium 1.6 and Xcode 8 and iOS 10.1 as simulator OS. I ran my appium server and set the desired capabilities and used an .ipa from the app store and it crashes on launch while doing an inspect on appium. Is it happening because i don't have a app signed for development?  what are the requirements for the app to be tested for using? Do i need signed apps to be used for testing on simulator too ?</p>
