Hello,
There are two new pull requests to the AeroGearOAuth2 and AeroGearHttp libraries to bring them up to date with the latest Xcode 8 beta (beta 3) and Swift 2.3. They are PR #53 on OAuth2 and #70 on Http. Note that for the Http project, PR #70 overrides previously submitted PR #67.
Once these are merged in, I plan to open new branches for iOS 10 targets and Swift 3. Both will potentially be pretty hairy, as iOS 10 changed a number of behaviors related to NSURL and Swift 3 contains a whole host of changes to the language. I don't think there will be any harm in having minimum targets for either project be at least iOS 9, but they should also be compatible with iOS 10.
