nityException: Launching iOS project via Xcode4 failed

Unity Engine

I was building my iOS project without problem a few days ago. I have added some small bits (5 simple models, amended some code and prefabs), but now a build fails. It opens Xcode then goes back to Unity and stays there, with the spinning beachball. Eventually it fails with the message:

I checked the log, and the section below seems the relevant bit. The first 2 lines appear repeatedly, but I have only included the last few.

I am using Unity 4.3.2, Xcode 5.1.

Any suggestions?

I tried a project I was working on last week, and now it is timing out also. I am not sure I had done a build since updating Xcode to 5.1. Are there any issues with the latest Xcode?

3

At least in my machine with XCode 5.1 Build&Run doesn’t run the project automatically.

4

Yes, there are still problems with the latest xcode: the ‘build and run’ does not start the xcode build automatically. You have to start it manually.
Hope they fix it someday…

5

‘Build And Run’ was working fine on the recent version of Xcode I was using prior to 5.1

The problem is I have no Xcode project created. Neither ‘Build’ nor ‘Build And Run’ are creating an Xcode project.

‘Build And Run’ opens Xcode, but it immediately closes again.

6

I have removed the Prime31 Game Center plugin I am using just in case. It has not solved the problem, but I noticed something appear that I have not seen before.

A progress bar appeared along with Xcode opening, labelled “Deploying Player”. It remained there at about 20% progress after Xcode closed, and stayed for long time while the spinning beach ball was showing. It only disappeared as Xcode opened again (showing the project selection screen) and the UnityException: Launching iOS project via Xcode4 failed appeared in the Unity console.

7

I have the exact same problem. Nice to know I’m not the only one.

8

Exact same problem here. Has to do something with the new version of Xcode. Very annoying.

9

I have reverted to Xcode 5.0.2, which allows me to do builds again.

To do that:
Delete Xcode.
Restart your Mac.
Log into your developer account.
At the bottom of the area for downloading Xcode 5.1, you will see a link asking if you are looking for an older version. Click on that and download the older version, then install.

10

Thanks @moonjump for finding a temporary solution but the problem seems to be that with 5.0.2 you cannot develop on devices with the newest iOS version, can you? At least that was the reason I updated Xcode in the first place… I wonder why we are the only ones who seems to have this problem? Are we the only ones who updated Xcode :slight_smile:

11

You can fix Xcode 5.1 support by manually editing Unity Xcode plugin metadata.

  1. Find following file in Unity installation:
  1. Open it with text editor and locate following lines here:
  1. Insert following line just before closing
  1. Restart Xcode.

P.S. proper fix is scheduled for Unity 4.5.

12

I have had a response to my bug report. It has been closed as a duplicate, so we are not the only ones. The following 2 options were given as workarounds, although I have not tested them as I am staying with 5.0.2 for the moment.

13

This worked for me, but my “Info.plist” file was in a completely different location than you listed:

/Applications/Unity/Unity.app/Contents/BuildTargetTools/iPhonePlayer/Unity4XC.xcplugin/Contents/Info.plist

14

Thanks for spotting it! I fixed my original post.

15

Fixed it. Thanks!

16

Thank you for the solution! This is probably the 3rd time this has happened to me after upgrading Xcode, and usually I just wait for a Unity update to resolve it. In an effort to not be held up by this issue again, I just wanted to document what I think is the solution for future Xcode updates here (for myself and others).

I think the value Mantas recommended in step 3 comes from:
Xcode.app/Contents/Info.plist

Look for the DVTPluginCompatibilityUUID key and add its value into the plugin info like Mantas suggested.

17

Thanks for this thread. I upgraded to Xcode 5.1 today and ran into the same issue. Mantas’ solution worked.

18

Mantas Puida solution works also for me with Unity 4.3.4 and xCode 5.1.1.
MANY THANKS

19

Thansks very much, that also works for me :slight_smile:

20

Editing the info.plist worked for me as well.
Thanks a million.
