Open Radar

 
Summary:
I test software that needs to run with Xcode 5.1 - Xcode 6.0.1.  I do a lot of regression testing.

I have side-by-side installs:

* /Xcode/5.1/Xcode.app
* /Xcode/5.1.1/Xcode.app
* /Xcode/6.0.1/Xcode.app

I have my daily working version of Xcode (5.1.1) installed in:

/Applications/Xcode.app

I have been using this configuration since Xcode 4.3.1.

```
$ echo $DEVELOPER_DIR
< not set>
$ xcode-select --print-path
/Xcode/6.0.1/Xcode.app/Contents/Developer
```

I downloaded and installed Xcode 6.0.1.

Then I restarted my machine.

I tried to open Instruments.app and it just hangs.

I have attached a crash report.

I found this output in the Console logs.

```
18.9.14 11:47:21.331 AM Instruments[5806]: Unknown class XRTextViewScroller in Interface Builder file at path /Xcode/6.0.1/Xcode.app/Contents/Applications/Instruments.app/Contents/Frameworks/InstrumentsKit.framework/Resources/XRScopedTextControl.nib.
```

Steps to Reproduce:
1. Download Xcode 6.0.1
2. Install
3. Restart
4. Open Instruments.app
5. Select the Automation template.

Alternatively, try to profile an app from Xcode and select the Automation template.


Expected Results:
To be able launch the Automation template.

Actual Results:
Instruments hangs.

Xcode 6.0.1
Build version 6A317

$ system_profiler SPSoftwareDataType

Notes:
I was able to launch the Xcode 6.0.1 Instruments.app on Yosemite 10.10 14A361c.

Works on Xcode 5 - Xcode 6 GM.

Does not work on Xcode 6.0.1.
