Xcode 7.3.1 autocomplete code completion not working

Question

Ever since Xcode 7.3 the autocompletion or code completion doesn't work properly.

I have tried:

• Deleting Derived Data folder
• Clean Targets and Build
• Reinstalling Xcode

It does autocomplete after you type it out fully the first time. But if you haven't referenced it once (i.e. like enums) it only shows what you typed out before (not showing full list of enums). Pressing escape doesn't help either.

Any other suggestions? Or anyone else experiencing the same?

Answer 1

Without doing anything, In Build-Settings -> Deployment changing iOS Deployment target from 8.0 to 8.1 resolved the issue for me.

It also works for XCode 6 as mentioned here

Also works on Xcode 8, Simply change the deployment target from iOS 9.0 to iOS 9.1.

Answer 2

Xcode 8 has now fixed this very annoying autocomplete issue. So anyone who is still having this problem, update to Xcode 8.

Edit: Please note, this has not solved for others. So your milage may vary. For me, it has fixed without doing anything extra. But they are using their new 'intelligent' autocomplete. Thinking about it, it could be part of the indexing. Deleting the DerivedData folder could help.
