IOS builderrors reg. namespaces

Hi

Our buildprocess breaks when trying to build for IOS.

We are using 2.8.14 f1

We get 102 namespace errors in the editorscripts akin to this one:
"Assets\I2\Localization\Scripts\Editor\Inspectors\TermsPopup_Drawer.cs(130,47): error CS0246: The type or namespace name 'SerializedProperty' could not be found (are you missing a using directive or an assembly reference?)
"

We have added an assembly definition to the I2 folder with "all Platforms" checked, and an assembly definition reference for Unity.TextMeshPro.

The Editor.iOS_I2Loc.X .dll import settings has been set to include Editor and IOS

We tried to add an assembly definiton to exclude the editor scripts folder on build, but it had no effect.

The current setting will only give builderrors but without errors when running in editor or on standalone.

Any suggestion on where I'm messing up in the settings?

Best regards

Pelle
