nityException: Launching iOS project via Xcode4 failed

you need to do the DVTPlugin thing again. And when it says your device is ineligible go to the menu product>Destination and select your device from there.
Follow Prime31's twitter feed, he often posts very useful info for this sort of thing

 

Thanks!

 

Just updated to today's latest Unity Pro 4.6.5f1, and have the latest XCode release (6.3.1) in Yosemite, but it still logs "Launching iOS project via Xcode4 failed."

Of course I can still build and run from within Xcode after the error, but it would be great to avoid the extra steps (and watching the progress bars to know when you can proceed with them).

Is this always the case for all users who don't apply their own manual hacks? Or is it project-specific. If the latter, I can file a bug.

 

Where do you find the latest UUID to fill in? I just updated to XCode 6.3.2, and I guess I need the latest one to update the Unity file with.

Edit: Nevermind found solution. Just have to enter this in the Terminal:

defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID

Aww, and now with XCode 6.4 this solution no longer works.

 

I have just upgraded to Xcode 6.4 and have also got the return of "Launching iOS project via Xcode4 failed". At least the solution I listed earlier in the thread works (a response I got from Unity QA): Navigate to the Xcode project in your build folder and manually open it.

It is quite a faff though. Hopefully there will be a longer term solution than Unity responding in their next update after each Xcode update.

 

It is working for me on xCode 6.4. Here is what I did:

• Read the DVTPlugInCompatibilityUUID as commented before (this value changes between xCode versions):

$ defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
7FDF5C7A-131F-4ABB-9EDC-8C5F8F0B8A90​

• Locate the Info.plist to modify:

$ find /Applications/Unity/Unity.app/ -name "Unity4XC.xcplugin"
/Applications/Unity/Unity.app//Contents/PlaybackEngines/iossupport/Tools/OSX/Unity4XC.xcplugin​

• Finally, add the UUID:

<key>DVTPlugInCompatibilityUUIDs</key>
<array>
<string>...</string>
...
<string>NEW_UUID</string>
</array>
​

After this, I ran my project from Unity and it launched on xCode and it alerted me that the plugin is not provided by Apple. I clicked on "Load Bundle" and it works now.

I've written an editor extension to solve this problem. Now you can fix this error by a simple click.
