Dyld symbol not found Dictionary Generator (IOS Xcode6 Beta4)

Question

I have a lower log error after compiling with the latest version of Xcode6 Beta4. However, there is no problem with Xcode6 Beta3. I do not know what the error message is. I am new to xcode. Please, help.

dyld: Symbol not found: __TMPdVSs19DictionaryGenerator Referenced from: /private/var/mobile/Containers/Bundle/Application/512B4D3F-F81E-42EF-9FD9-D808B066A833/* Expected in: /private/var/mobile/Containers/Bundle/Application/512B4D3F-F81E-42EF-9FD9-D808B066A833/IRApp.app/Frameworks/libswift_stdlib_core.dylib in /private/var/mobile/Containers/Bundle/Application/512B4D3F-F81E-42EF-9FD9-D808B066A833/* 

Thanks in advance.

Quote from Apple Developer Forums :

• Delete derived data (window / organizer)
• Clear (Cmd + Shift + K)
• Restart on the device after all indexing and that has been completed (sent at the top of xcode)

It seems that since the advent of the new beta there have been several bugs like this floating one. Although the error messages are not exactly the same, they seem to have the same answer. I personally came across this with a third range-related error, and that was the solution in this case.
