Swift Static Libraries causing build error only with cordova build command (works fine in Xcode UI)

Bug Report

Problem

Can't compile a project which has Pod distributed as Swift Static Library.

What is expected to happen?

The Project should compile without any errors

What does actually happen?

The Project compiles with the below error:

<unknown>:0: error: module map file '/Users/sachinvas/Library/Developer/Xcode/DerivedData/MyApp-djlbvgkjcelsaocynsvraskofynn/Build/Products/Debug-iphonesimulator/Starscream/Starscream.modulemap' not found
<unknown>:0: error: module map file '/Users/sachinvas/Library/Developer/Xcode/DerivedData/MyApp-djlbvgkjcelsaocynsvraskofynn/Build/Products/Debug-iphonesimulator/Starscream/Starscream.modulemap' not found
<unknown>:0: error: underlying Objective-C module 'SocketIO' not found
/Users/sachinvas/Projects/Private/myapp/platforms/ios/Pods/Socket.IO-Client-Swift/Source/SocketIO/Engine/SocketEngine.swift:27:8: error: cannot load underlying module for 'Starscream'
import Starscream

Any updates on this issue?

No, as you can see there are not comments or other changes.

Your issue doesn't show any errors in "The Project compiles with the below error:" by the way.

[sachinmobstac]

@janpio, Sorry for that. I will add more details. Looks like there is a path issue when using the xcodebuild command vs the Xcode UI. I know Xcode UI uses the xcodebuild command to build the project, however I am not sure why the path gets resolved when using the Xcode UI and throws error when using the xcodebuild command.

@janpio, I have updated the issue which reflects the error which I am facing and added additional information.

Thanks, that might give an user or contributor that knows more about Swift/Pods/iOS something to go on.

It's probably due to this CocoaPods bug: CocoaPods/CocoaPods#10675 (which has been sitting there for 1 year, so I'm not sure how long before, or if, it will be fixed...

A workaround would be to run xcodebuild without a CONFIGURATION_BUILD_DIR. Would that be possible?

A workaround would be to run xcodebuild without a CONFIGURATION_BUILD_DIR. Would that be possible?

Not sure how far this will get you, or if you can unset CONFIGURATION_BUILD_DIR, but you should be able to configure it via buildFlags which can set in either build.json or via --buildFlag CLI argument.

So if something expects a specific build directory, then in theory you should be able to set it to the expected value. I don't know if this will cause any other unwanted side effects however.
