Issue Description:

People have tried to use Swift in Xcode Run Script build phases, but because Swift looks at the SDKROOT environment variable, the Run Script phase will fail when building a non-macOS target:

<unknown>:0: warning: using sysroot for 'iPhoneOS' but targeting 'MacOSX'
<unknown>:0: error: unable to load standard library for target 'x86_64-apple-macosx10.14'

We should just ignore SDKROOT when running the interpreter. Swift knows how to invoke xcrun to find the right SDK when it's not passed one explicitly.

研究方向
The issue is about the Swift driver ignoring SDKROOT environment variable when running in interpreter mode. Look into the Swift driver source code, specifically how it handles SDKROOT and how it can be overridden when not passed explicitly. The fix likely involves conditionally setting the SDK based on xcrun invocation instead. Check comments on the issue for any hints.
