ld: library not found for -lCocoaAsyncSocket

I'm using App Center to manage the build for iOS and the following is error I'm receiving in the build output:

    ld: library not found for -lCocoaAsyncSocketclang: error: linker command failed with exit code 1 (use -v to see invocation)** ARCHIVE FAILED **##[error]Error: /usr/bin/xcodebuild failed with return code: 65

I ran the build in Xcode and the archive was successful.

Any thoughts on why this fails in App Center ?
