how to fix xcode AppDelegate error while running project?
提问by ecatalano
I am a very beginner in iOS development and it's my first project in Xcode 6.4. Although my project is empty (I didn't write any code yet) it's crashing while running on the simulator. Can anybody please help me fixing this issue?
我是 iOS 开发的初学者，这是我在 Xcode 6.4 中的第一个项目。虽然我的项目是空的（我还没有写任何代码）它在模拟器上运行时崩溃了。有人可以帮我解决这个问题吗？

Might be issue with outlet connection. You may rename the outlet connection name.
可能是插座连接问题。您可以重命名插座连接名称。
Do one thing restart Xcode and clean your Xcode and then run the application simulator or device. I hope it will work.
做一件事重新启动 Xcode 并清理您的 Xcode，然后运行应用程序模拟器或设备。我希望它会起作用。

Check your methods for something named "doneEditting"
检查名为“doneEditting”的方法
My guess is that you accidentally added an extra "t" in the word editing, which is what caused the problem.
我的猜测是您不小心在单词编辑中添加了一个额外的“t”，这就是导致问题的原因。

Well thank you all for your help. I figured out how to solve my problem.
I clicked on each and every element on my Main.storyboardand went to the Show the Connections inspectorin the Utilities(right sidebar) and deleted every connection each element on my storyboard had.
嗯，谢谢大家的帮助。我想出了如何解决我的问题。我点击每一个元素在我Main.storyboard去了Show the Connections inspector的Utilities（右侧栏），并删除了所有的连接上我的故事板的每个元素了。
