2015.06.08苹果放出了iOS9以及Xcode7的 Beta测试版本。有一句话非常引入注意：

https://developer.apple.com/xcode/

Now everyone can get their app on their Apple device.

Xcode 7 and Swift now make it easier for everyone to build apps and run them directly on their Apple devices. Simply sign in with your Apple ID, and turn your idea into an app that you can touch on your iPad, iPhone, or Apple Watch. Download Xcode 7 beta and try it yourself today. Program membership is not required.

这里面隐藏了很大的文章。精彩内容随后放出。
