Swarm has had a feature for a long time where you can allow your friends to check you in. It's more than just tagging a friend in a checkin, since it actually creates a full-fledged checkin on the other person's account. It's an interesting feature of Swarm, and not something I've seen elsewhere.
I normally don't like to launch a feature that's this rough around the edges, but I decided to anyway. I added a section to the OwnYourSwarm dashboard that will let you import a specific checkin by its Foursquare checkin ID.
An interesting feature of the Swarm app is how it handles photos uploaded to checkins. If you check in and attach a photo, the checkin is actually created before the photo is uploaded. If you're on a spotty Internet connection, you'll see this because your checkin will exist and you'll get points for it, but there won't be a photo yet. The app will then continue to upload the photo separately, retrying if it fails. This is actually a really great app design on the part of Foursquare, but does lead to some tricks with the API.
Now that I can post checkins on my website, the next step is to automatically copy my checkins from Swarm! I still like the experience of Swarm, and I still get value out of their analysis of my checkins, so I don't see myself leaving Swarm anytime soon. This way, I get the best of both worlds.
So this is working now! A clock which moves its hands to show what category of venue I've last checked in at. Next step is to add more hands for my friends who still check in all the time on Swarm! #weasleyclock#harrypotter#swarm#foursquare
I've only had Foursquare's new "Swarm" app for a day, but I'm already super impressed. By trimming out all of the search/review features, they're able to focus the app on providing a great checkin experience and providing more ways to connect with your friends.
The "login" process of Foursquare's new @SwarmApp was impressive. It already knew my Foursquare account and I didn't have to sign in or OAuth or anything! Current thinking is they're using the new UIDevice identifierForVendor property which returns the same ID across multiple apps by the same company.
