XCode 6自动完成停止工作

Question

XCode 6 Beta 5 and autocomplete stopped working. I thought problem in Beta 5 but I've reinstall to Beta 4 and it's still not work but it did before. I check preferences for "suggests" and I tried to delete Derived Data but it doesn't help

Answer 1

1. Clear derived data.
2. Under build settings, select Always Search User Paths to "YES".
3. Clean the project.

Answer 2

This happened to me recently because I had a /* */ style comment after the @end of my @implementation.

Not sure why that would break autocomplete but moving the comment into the implementation fixed autocomplete.

There seems to be a lot of reasons autocomplete breaks. Just adding to the list..

Answer 3

I found the solution. Problem was in an array. I have big array like: let array:[NSString] = ["first","second"...] I changed it to var array = ["first","second"...] I don't why it's happened but it works. It was so hard to find the problem.

Answer 4

I was having this problem.

This is what worked for me.

1. Clear derived data.

Window -> Organizer -> "Select you project" -> Delete Derived Data.

2. Clean the project

3. Quit Xcode ----- this is very important. You might have to restart you computer.

4. Open Xcode again

Hope this works for you. This worked on 2/9/2015

Answer 5

检查.m文件是否已在“目标成员资格”中签入

Answer 6

Tried to clean/delete derived data multiple times. Autocomplete was disabled in some files, but not App Delegate. After a while I saw red libraries int he project navigator. Those are managed by cocoapods. The solution turned out to be:

• Navigate to the project root folder
• Delete "Pods" directory
• open terminal, type cd
• drag the project folder there to get full path
• run pod install

Upon reinstalling pods, syntax highlighting and code completion is restored in the affected files.

Answer 7

For me it was because it was a new problem since upgrading my version of Xcode. After downloading the documentation again, everything worked fine.
