SpringBoard was unable to servic

（我只是搬运工）

xcode 8.0 beta 运行模拟器报错SpringBoard was unable to service the request.

大神解决方法：

Problem solved for by an Apple Engineer in the lab. It's an issue they're working on. The bottom line was that when I copied Xcode to Applications folder, there was a bit set on it and that was preventing it from communicating with the simulator.

To fix it: Copy-paste Xcode-beta.app from Applications folder to somewhere else, e.g. Documents folder. Delete Xcode-beta.app from Applications folder. Move Xcode-beta.app from Documents to Applications folder again.

翻译一下： 就是将Xcode-beta.app先从应用中移到其他地方（桌面、文件夹。。。）,再把应用中的删除。完了之后将原先移到的app再移回到应用中。亲测解决了！
