I don't know what's wrong with my xcode. My project could run on my iphone properly (so I guess there is nothing wrong with my project). But in the Xcode editor, I couldn't "jump" to function or variables definition. it shows
this could be fixed by just restarting Xcode.However, after about a few minutes, it doesn't work again...
I already check Xcode 6 Swift code completion not working But no luck..
my swift version is 1.2, and Xcode version is Version 6.4 (6E35b)
any one help?
