SDK 8+ database module appears to be not building

[micksolo]

Whenever I try to add
<module platform="iphone">firebase.database</module>
to tiapp.xml I cannot get the simulator to build my app anymore. Removing that line from tiapp.xml and the app builds fine.
The error I get in the console is

[INFO] Invoking xcodebuild
[ERROR] ** BUILD FAILED **
[ERROR] The following build commands failed:
[ERROR] Ld /Users/mick/Documents/Projects/chatapp2/build/iphone/build/Products/Debug-iphonesimulator/chatapp2.app/chatapp2 normal x86_64
[ERROR] (1 failure)

I have tried SDK 8.0.0 8.0.1, 8.1.0, 8.2.0 and 8.2.1 and have the same issue.
