Ok to elaborate a little, I love my old 17” MBP. But it’s dual core, and I have a 15” a few years younger that is quad core. To do anything on the 17” with Xcode 7 (and the previous version) is basically impossible. While I could get the 15” to run it smoothly, I quickly exceeded what I wanted to do in Xcode with playgrounds. If you want to learn Swift for example, and you want to play with some basic functions, it might work out well, but if you want to play with views and controllers and models and make something, then it quickly becomes a waste of time IMHO. If you look at the WWDC ’15 vids, I think they realize it too, and you may find as I did that they are kind of pitching playgrounds at this point as a learning experience. So perhaps if you’re learning Swift or you are an educator you may find playgrounds very useful. But if you’re making apps and trying to make money it’s not worth your time, again, IMHO.
As for Swift 2.0, and Xcode 7 beta, I love them both. I am actively working to finish an app that is in Swift with Xcode 6.3.2 and migrating it daily into the other MBP with Xcode 7 beta every night just to stay on top of the latest and greatest. I expect we will launch our app prior to the Fall and iOS9 and don’t want to be hindered by the beta and 2.0 being the final product, as in previous betas you could not pass review if it was produced in beta.
Xcode 7 and Swift 2 have been the most stable versions of betas I’ve seen thus far but my Apple experience has only been from Xcode 5 and Obj-C and quickly Switched to Swift because of my past experiences with Java and Swift was simply more enjoyable to work with.
Hope that helps.

This will (I hope) be corrected in the beta that according to patten should be out week after next, but in the mean time it’s frustrating to read all the blogs on what people are delighted to find in Swift 2.0.
