I'm aware of the known issue with AIR and Xcode versions greater than 9.2, as per Cannot compile AIR app with Xcode 9.3 iPhoneOS11.3.sdk . The recommendation is to use Xcode 9.2 until an AIR update is released. Unfortunately this workaround will not work for us.
The ANE we're building relies on a new framework added in iOS 11.4. The SDK for 11.4 was added in Xcode 9.4.
Is there a workaround, pending release of a new version of AIR? A beta we can use? Something we can modify ourselves, within AIR or Xcode?
Thanks!
