I am trying to get Sync (<https://github.com/hyperoslo/Sync>) to work in my 'em' Xcode iOS Swift project. I have experience with Carthage for framework dependency so it is my cocoapods premiere.

my Podfile

```
use_frameworks!

target "em" do
    pod 'Sync'
end

```

my Pods dir:

ld: framework not found DATAFilter
clang: error: linker command failed with exit code 1 (use -v to see invocation)

```

My question is - Is neccessary somehow manually link the DATAFilter framework?
