I have noticed this problem as closed before but I am getting the same problem.

P.S - I have imported Alamofire in the class mentioned in the screenshot

Here is my pod details

platform :ios, '10.0'

use_frameworks!
target 'PhotoTagger' do
     pod 'Alamofire'
end

Also the only thing being auto completed is AlamofireVersionNumber and i cannot access anything when I am trying to use the auto complete feature. Now if i write Alamofire by hand then I can access some methods, but then again something is going wrong and code is not compiling, which i think boils down to the issue that the class isnt being fetched by auto complete.

I have tried -

In Project settings > Build settings

1. Always search user path To YES
2. Header search path to only include "$(inherited)" as non-recursive

All other pods are working fine, except Alamofire. Also after writing class name by hand or copy pasting, some of the methods that are being auto completed does not have the same signature of the actual method of the Alamofire class

Please please please !! help me sort this out, so that someone out there when facing this can help themselves too. There isnt any solution to this as of now.

P.S

I had opened an issue on Alamofire's Github page, but they responded with

Sorry, we're not responsible for Xcode's autocomplete issues.
In the future, you should open questions like this on Stack Overflow
and tag alamofire.

Cheers. 

Please help, I am stuck with this for quite some time.

EDIT :

Here is my project settings details Also, I have build the project and still the problem persists.

P.S - Writing the class manually by hand , and the methods even, it compiles but everytime, I have to go to the github page, to copy paste the method signature, The problem is that with Autocomplete, i can navigate all method signatures and know about the public available methods. But I am only restricted to the example methods available in github, as everytime I have to copy paste the methods and the overwrite the implementation. Again, this compiles and runs, but the auto complete is not working, not for the class, or for the functions.
