I get an error when I try to build an empty RN project using Firestack from the branch v3.

I get the following error:

/[...]/TestProject/node_modules/react-native-firestack/ios/Firestack/FirestackCloudMessaging.m:74:28: error: expected method body
- (void) requestPermissions(NSDictionary *)requestedPermissions

Current environment:
OS X 10.12.1
XCode 8.1 & 7.2.1
react-native-cli: 2.0.0
react-native: 0.39.1

Steps to reproduce:
react-native init TestProject
cd TestProject
The app compiles and runs properly at this stage.

npm i -S fullstackreact/react-native-firestack#v3
react-native link react-native-firestack
cd ios && pod update --verbose
cd .. && react-native run-ios

This is where I start getting the aforementioned error.
Same error when I try to run the project from TestProject.xcworkspace

Has anyone else encountered this issue?
