Xcode 6.3从故事板导航到其他Swift 1.2文件时崩溃 [英] Xcode 6.3 Crashes when navigating from storyboard to other Swift 1.2 file

问题描述

我安装了Xcode 6.3，其中包括对Swift 1.2的支持。它出现了大量的错误信息，主要是铸造问题。

I installed Xcode 6.3 which includes support for Swift 1.2. It turned up a ton of error messages, which are mostly casting issues.

我导航到故事板，并且无法返回任何其他 .swift 而不会导致整个事情崩溃。我强制退出，重新启动，甚至重新安装，我仍然无法离开 Main.storyboard 文件。

I navigated to the storyboard, and cannot go back to any other .swift without the whole thing crashing. I have force quit, restarted, and even re-installed, and I still can't navigate away from the Main.storyboard file.

我已经尝试此处描述的建议打开故事板代码，进行一些更改，还原这些更改，保存并再试一次，但仍然没有运气。

I have tried the suggestion described here to open storyboard as code, make some changes, revert those changes, save and try again, and still no luck.

我的代码中有什么东西会破坏Xcode吗？还有其他人遇到过这种情况吗？我使用相同的代码库成功使用了Xcode 6.3 beta。

Is something in my code breaking Xcode? Is anyone else experiencing this? I had used Xcode 6.3 beta successfully with the same codebase.

更新：
现在已在 Xcode 6.3.1 于2015年4月21日发布。

Update: This has now been fixed in Xcode 6.3.1 released on the 21st of April 2015.

推荐答案

我从苹果开发者论坛收集到这是一个 @IBDesignable 问题。特别是在使用自定义字体，其他xib等的项目中。

I gather from the apple developer forums that this is an @IBDesignable issue. Especially in projects that use custom fonts, additional xibs, etc.

通过从swift UIView类中删除所有 @IBDesignable ，我以某种方式修复了我的问题定义。您可以使用TextMate或其他方式打开项目目录，搜索并删除所有@IBDesignable

I have somehow fixed my issue by removing all @IBDesignable from swift UIView class definitions. You can open your project directory with TextMate or other, search and remove all "@IBDesignable"

但是我仍然认为这是一个主要的bug，需要处理..所以请继续向Apple提交错误报告。

However I still think this is a MAJOR bug, that needs to be worked on.. so keep filing bug reports to Apple.
