I just installed an additional dependency (HockeyAppSDK) using CocoaPods for my Swift iOS project and now my project fails during build giving me the error:

clang: error: cannot specify -o when generating multiple output files

I uninstalled the dependency and the project still fails during build with the same error. Any ideas on how to fix this?

EDIT: When building using the xcode cli the errors looks like:

2015-07-24 20:28:09.378 xcodebuild[34313:1668414] stream error: stream error at offset 29: created by an unsupported XCDependencyGraph build

The following build commands failed:

CompileSwift normal arm64 {Path to swift file}

CompileSwift normal arm64 {Path to swift file}

CompileSwift normal arm64 {Path to swift file}

CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compile

This was a bug in CocoaPods 0.38.1 as this issue indicates. So this is probably fixed in future versions of CocoaPods.

What you can do to fix the problem temporarily before a new CocoaPods release: the bug is that somewhere in the private xcconfig files, there is missing a space before -isystem

EDIT:

A new version of Cocoapods (0.38.2) is released that fixes this issue
