Xcode AutoFill stopped working

Question

Xcode 6 Beta 5 and autocomplete has stopped working. I was thinking about a problem in beta 5, but I reinstalled it on Beta 4 and still didn't work, but before. I check the settings for the "suggestions" and I tried to remove Derived Data, but this does not help

Answer 1

I have found a solution. The problem was in the array. I have a large array like: let array:[NSString] = ["first","second"...] I changed it to var array = ["first","second"...] I do not understand why this is happened, but it works. It was hard to find a problem.

Answer 2

• Clear the received data.
• In the build settings, select "Always search for user paths" to "YES."
• Clean up the project.

Answer 3

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

I don’t know why this would break autocomplete, but by moving the comment to fixed implementation autocomplete.

There seem to be many reasons for autocomplete overflow. Just adding to the list.

Answer 4

I had this problem.

This is what worked for me.

• Clear the received data.

Window → Organizer → "Select Project" → Delete Derived Data.

2. Clean up project

3. Close Xcode ----- this is very important. You may need to restart your computer.

4. Open Xcode again

Hope this works for you. It worked on 9/9/2015

Answer 5

Check if the .m file has been installed in the Target Membership section

Answer 6

Tried to clear / delete derived data several times. Autocomplete has been disabled in some files, but not the App Delegate. After a while, I saw red libraries in his project navigator. They are controlled by cocoapods. The solution turned out to be:

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

After reinstalling the containers in the affected files, syntax highlighting and code completion are restored.

Answer 7

For me, this was because it was a new issue since updating my version of Xcode. After loading the documentation, everything worked fine again.
