Xcode 7.2 (7C68) (latest as of 28 December 2015)
Typhoon 3.4.4 (again, latest as of 28 December 2015)
Pulled repo, changed API key, receive runtime error.
FIX: Add "TyphoonGlobalConfigFilenames" to PocketForecast-Info.plist and point at the Configuration.plist:
<key>TyphoonGlobalConfigFilenames</key>
<array>
<string>Configuration.plist</string>
</array>
I guess the Typhoon framework has changed and now required this rather than looking for it via filename convention..?
