In Xcode 10 there seems the export option is not available for Development / Adhoc / Enterprise mode.
But for when we go through "Distribute app" and choose "iOS App Store" then it show "Export" option there.
And if I choose to proceed with any other option other than "iOS App Store" then I end up in the following screen.

So how to export a build with Adhoc / Development mode ?
