Cannot install AIR app to Apple device after upgrading MacOS

Hi,

Since updating MacOS to 10.13.4 I can no longer install AIR Debug or AdHoc apps to any Apple device.

e.g. I get the following error:

iPhone X: The device has encountered an unexpected error. Error connecting to your device!

I can publish the app successfully without installing it onto the connected device.

I can also publish an App Store ready app and submit it to Apple and install the app onto the device via TestFlight so it does seem the .ipa itself is being created successfully.

iOS 11.3

MacOS 10.13.4

iTunes 12.7.4

AIR SDK 29.0.0.122

Animate 18.0.1 Build 115

Xcode 9.2

iOS SDK 11.2

All Apple certificates and provisioning profiles are in date and were working before the update.

Does anyone have a workaround for this?

Thanks,

Mark
