I have recently updated my Xcode and started having this error.

```
2014-11-03 15:03:54.222 App[13141:60b] Error loading /private/var/mobile/Applications/677127BD-5230-4D5F-B70E-AF728439D34B/tmp/AppTests.xctest/AppTests:  dlopen(/private/var/mobile/Applications/677127BD-5230-4D5F-B70E-AF728439D34B/tmp/AppTests.xctest/AppTests, 262): no suitable image found.  Did find:

DevToolsBundleInjection: Error loading bundle '/private/var/mobile/Applications/677127BD-5230-4D5F-B70E-AF728439D34B/tmp/AppTests.xctest'

```

I have done my Google search as usual. But I haven't found any solutions yet. Source I have looked and tried to resolve my issue with is,

**When it happens?**

It only shows this error if I run uni test on device. On simulator it works as expected. Running application from normal target does not show this error.

**When error shows up while running Uni Test app does not crash. It just fails to load xctests.**

Anyone having similar issues? and manage to resolve it?
