"Symbols not found" when using 'rake device'

Question

I am getting the following error when running rake device on any RubyMotion project

*** symbols not found in `/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.0': debugger might be slow to attach

How do I fix this?

Answer 1

The Symbols folder is missing in the DeviceSupport/7.0 folder.

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.0
sudo ln -s ../../Developer/SDKs/iPhoneOS7.0.sdk Symbols

After that you should have the following symbolic link in your 7.0 folder

Symbols -> ../../Developer/SDKs/iPhoneOS7.0.sdk

That solved it for me.
