警告：检测到 UUID 与加载的库不匹配
自从更新到 5.0.1 以来我一直收到这个
警告：检测到 UUID 与加载的库不匹配 - 在磁盘上是： /Users/alfredjunco/Library/Developer/Xcode/iOS DeviceSupport/5.0.1 (9A405)/符号/系统/库/框架/CoreLocation.framework/CoreLocation
我也得到了这个，但我不知道这是否重要
无法加载符号文件：警告：无法读取符号 /Library/MobileSubstrate/MobileSubstrate.dylib（未找到文件）。 警告：本地未找到 MobileSubstrate.dylib 的副本，读取自 远程设备上的内存。这可能会减慢调试会话的速度。
i have been getting this since updated to 5.0.1
warning: UUID mismatch detected with the loaded library - on disk is:
/Users/alfredjunco/Library/Developer/Xcode/iOS DeviceSupport/5.0.1
(9A405)/Symbols/System/Library/Frameworks/CoreLocation.framework/CoreLocation
i also got this one but i don't know if it matters
unable to load symbol file: warning: Unable to read symbols for
/Library/MobileSubstrate/MobileSubstrate.dylib (file not found).
warning: No copy of MobileSubstrate.dylib found locally, reading from
memory on remote device. This may slow down the debug session.

您最近安装了 Spire 吗？
如果你这样做了，只需卸载 Spire 就一切正常了。
Have you recently installed Spire?
If you did, just uninstall Spire and everything will be Ok.
当 xcode 中没有设备支持时，通常会发生这种情况。
您可以参考以下链接获取详细答案..

另请听听上面 jennifer 的评论。 。
this generally happens when you do not have device support in xcode ..
You can refer to bellow link for detail answer ..

以下内容对我有用：
我在使用 xCode 4.0.2 的 iphone 3G（4.2.1，JB）上遇到了这个问题。它给了我关于不匹配的 UUID 的错误，并在达到一些太多的错误后停止。沿着他们正在寻找的文件的路径，我只是在它们弹出时重命名它们，直到我强行重命名所有文件：
所以我将文件重命名为：
然后
错误是：
我不确定这最终会做什么，但它允许我在 xCode 4.0.2 上的 JB iPhone 3G (4.2.1) 上进行调试，我必须卸载 xCode 4.2 并重新安装 4.0.2。我还必须重新安装 iTunes
The following worked for me:
I ran into this on my iphone 3G (4.2.1, JB) using xCode 4.0.2. It gave me errors about Mismatched UUIDs and stopped after a few of too many were reached. Following the path of what file they were looking for I simply renamed them as they popped up until i brute forced renamed all the files:
So i renamed the file from:
to
Then the error was:
I'm not sure what this will ultimately do, but it allows me to debug on my JB iPhone 3G (4.2.1) on xCode 4.0.2 I had to uninstall xCode 4.2 and reinstall 4.0.2. Also I had to re-install iTunes
尝试改用 LLDB 调试器。安装了 Spire 后对我有用。
如何？单击运行按钮附近的目标名称（项目名称）并编辑方案。
Try to use LLDB debugger in stead. Works for me with Spire installed.
How? Click on your targets name (projects name) near the run button and edit scheme.
