好的,所以我的Xcode和iPhone模拟器最近变得非常搞砸了,我记得在这个开始发生之前做的就是我关闭了我的mac。所以,我的第一个问题是,每次我打开iPhone模拟器,它说模拟的应用程序无法运行,并要求切换sdk,我点击5.0,它继续说。我已经尝试过3次重新安装Xcode。其次,每当我打开MainStoryboard.iphone / ipad文件时,Xcode会冻结,并让我选择崩溃或继续处于不良状态或类似的状态。接下来,我正在尝试创建的应用程序曾经工作过,但突然之间,它会在启动时因此错误消息而崩溃:

这是我在开始运行应用程序时遇到的错误,相反,它只是在构建应用程序时给了我两个错误,这就是那些说法:
Command /Developer/usr/bin/ibtool failed with exit code 255
Verify exit code of build task 'CompileStoryboard MainStoryboard_iPhone.storyboard'
Build task failed without generating error messages.
这些必须在某种程度上相关,它与故事板设置或iOS模拟器有关,这对我的应用程序的制作来说是一个巨大的挫折,如果有人有这个问题,请帮助
编辑:好的一直在试图看看是否在其他项目中发生同样的事情,它似乎只是那个错误的应用程序,但IOS模拟器不适用于任何事情。另外,我尝试在Xcode上做的每一件事现在都会引发崩溃,甚至试图打开一个项目并在新窗口中查看错误。答案 0 :(得分:0)
更新到更新版本的Xcode,它们运行更顺畅,并且减少了很多错误。
