Unsupported clang availability platform: 'bridgeos'

Question

I'm trying to bind Custom Native iOS Framework and getting this error in the 1st stage of sharpie bind -output bindings. Below is the command and log when I hit the below command:

sharpie bind --output=filename --namespace=namespacename --sdk=iphoneos11.4 /path/to/the/headerfile

Logs:

Below are the details of command : sharpie xcode -sdks

Answer 1

We experienced the exact same issue, and solved it by uninstalling Xcode 9.4(or 9.3 if that is what you have), downloading Xcode 9.2 from apple, installing it and rebooting. After this you can use sharpie with iphoneos11.2 (instead of 11.4 which sharpie does not support yet it seems).

I assume some breaking changes was introduced with xcode 9.2 and the latest swift-updates.

NB: This is just to generate the bindings, afterwards, when you have the structs and apidefs, you can upgrade to xcode 9.4 and compile as usual...
