1. pod install
2. Open the Xcode workspace -> the Pods project -> the Upsurge target, Build Settings, change the Swift Language Version to 4.2.
3. Add a new plist to the project, named Config.plist.
4. Add these string properties to the plist, using the corresponding values from your Foursquare/Last.fm developer accounts:
   • FoursquareClientId
   • FoursquareClientSecret

Note that the app will work without the Foursquare config vars, but place lookups will fail, so you will be unable to assign venues to visits.
