Hello,
I successfully deployed my App on an iPhone (iOS 11 official) using Xcode 9 official and Unreal Engine
Version: 4.17.1-3586342.
And with the help of the UE documentation for iOS :
You must use a certificate generated on Apple developer website not in Xcode to get rid of the “Xcode managed” message.
And to make things easier for deployment, try use a wildcard (*) certificate.
By my side:
Build succeeded but launch finally failed.
The app is visible on the iPhone but crashed immediately after launch.
No log in console.
