Standalone in IDE Test Works; But Not From SA

[Sannyasin Brahmanathaswami]

LC 8.1.10 
iOS 11.4 on the iPhone

1) I can been able to push update from the IDE

  Develop
         Test
                myIphone   # it works on the phone

2) So know to go to SA build to create a version.
    Xcode
         Devices
              Select My Phone 
                     Add the App

  It crashed the moment it is launched.

Xcode says

"Could not locate support files)
This iPhone 7 (Model 1661,784,1785,1786) is running iOS 11.3(15F79), which many not be SSupported by this verSions of Xcode."

So, it builds from the IDE Test menu, but on Standalone Builder

Why?
