I've recently gotten back into iOS development, so I don't have a paid Developer account-- which is fine for now, I'm just playing around with ideas locally, but I'm wondering if I should pay up. The problem I'm having is that Xcode 7.3.1 has gotten rather unstable-- refusing to compile things, and throwing segfaults when trying to compile one file in particular. I suspect it's because of the move to Swift 2.2, and my use of the simd library and a rather elaborate (probably over-elaborate) set of generics and PATs. Problem is that it's hard to tell what the complier doesn't like if it just keeps segfaulting. It works ok in the Playground. Add to that the slow parsing of the Swift code and constant complaints that certain lines of code are "too complicated and taking too long to process" and I'm willing to brave a beta. So I'm wondering if there is a current Xcode beta available that I might try to use to get past this. Are the betas only visible to paid developers? Barring that, is there a way to get back to 7.2 without restoring from backup?
