Xcode 9.3 suddenly not parsing storyboard

Question

suddenly Xcode 9.3 storyboard give me an error " An internal error occurred. Editing function may be limited"

I try to:

• clean project
• remove DerivedData
• disable csrutil
• update Mac to latest, even to beta
• update to xcode 9.4 beta
• I moved the xcode to application path
• Reinstall the CommandLineTools

What else could occur this problem?

below is the error logs:

Version = 9.3 (9E145)
Plugin Version = 14109
Beta Version = 0
OS Version = 10.13.5 (17F35e)

Answer 1

After days of trying, I just formatted my Mac and the xcode works fine.

I don't know why, even the bug I reported to apple, not resolved!
