Xcode 6.1 swift autocomplete and code sense broken

Question

I am using Xcode Version 6.1 (6A1052d) , it is working well except the only problem is auto complete and code sense is broken for swift projects.

I can fix it by deleting derived data and the folder ~/Library/Caches/com.apple.dt.Xcode , which is described here , or changing the deployment target of the project from 8.1 to 8.0 .

However, the first solution only last me for 1 or 2 days, out of no where it doesn't work again, I don't want to delete the folders every so often or change the target iOS versions all the time. Please help me.

Answer 1

I have had the same issue for many days while working in swift, finally I have deleted some old data in the directory ~/Library/Developer/Xcode/DerivedData and started the xcode again and error is disappeared.

Hope it helps!

Answer 2

it's not gone .. I do this procedure 3-4 times a day while coding .. did anyone find a permanent fix? I'm on Xcode 6.3 beta on Yosemite.. on 6.1 I had to do this process more than 5-6 times per day, but they did not fix it entirely :(. I observed that working in one file and not switching back and forth really delays this from happening + if you work with collection views or table views and switch and modify in all files of your MVC architecture, there are greater chances you will need to restart Xcode (which in 6.3 beta fixes this issue automatically). If only there was a way to force a re-indexing on the project ..
