But when I reopen my project then it refresh.I tried below step but nothing happened Select storyboard->editor-> refresh all views and also automatically refresh already checked. Is this bug of Xcode 9.3?

I got the answer it's happened due to IBDesignable in my custom library class.If I remove all IBDesignable it's work fine.
