Always get build error : No such module 'Alamofire' - ios

Question

I followed the instruction of Alamofire in github,
I created an xcode project named cocoapods-test & I closed it.
I go to the project folder run pod init command which generates a Podfile. Then I added the following code to the Podfile:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!
pod 'Alamofire', '~> 3.0'
Then, I run command pod install and this is the result in terminal:
Updating local specs repositories
CocoaPods 1.0.0.beta.6 is available.
To update use: `gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information see http://blog.cocoapods.org
and the CHANGELOG for this version http://git.io/BaH8pQ.
Analyzing dependencies
Downloading dependencies
Installing Alamofire (3.3.0)
Generating Pods project
Integrating client project
[!] Please close any current Xcode sessions and use `cocoapods-test.xcworkspace` for this project from now on.
Sending stats
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.
Then, in my project folder there is a new file called cocoapods-test.xcworkspace . I double clicked it which opens my xcode again, and I can see the Alamofire module.
Then, I opened my project's ViewController class, and import Alamofire . But no matter how many times I clean & build, I always get error No such module 'Alamofire' . Here is the screenshot:
Why I get this problem though I followed the instruction step by step?
(I am using XCode 7.2.1, Swift 2.1.1 & Alamofire 3.3.0)
======= UPDATE ========
I tried #LK Yeung 's answer, uncomment import Alamofire, then clean & build again, I got a bunch of compiler errors from Alarmofire:

Answer 1

You need to build the project successfully once before using the library
comment import Alamofire -> build -> uncomment import Alamofire

Answer 2

Make sure you have opened the "project_name".xcworkspace instead of "project_name".xcodeproj .As you are working on pods all the installed pod will be available only in your .xcworkspace project file.

Answer 3

I was having this exact same problem. Please make sure that you are on Xcode 7.3 and using Swift 2.2.
You can check your Swift version using xcrun swift -version. Updating Xcode to 7.3 should also automatically update Swift.
Updating Xcode resolved this issue for me.

Answer 4

You need to add the lib to 'the Link Binary With Libraries' section also

Answer 5

You can try put pod 'Alamofire', '~> 3.0' like below. And run pod install again.
target 'yourtarget' do
pod 'Alamofire', '~> 3.0'
end

Answer 6

If you're manually installing Alamofire (or any other framework) make sure your build configurations match between both your parent project and the sub project. For example, if your build configuration in your project is called 'Development', but Alamofire's is called 'Debug' you'll get the 'no such module' error.

Answer 7

Follow This Sequence
➼ Open Terminal, go to the project folder and run these commands:
sudo gem install cocoapods -n /usr/local/bin
pod install
➼ Go to this link and clear derive data folder:
~/Library/Developer/Xcode/DerivedData
➼ Then open project "xcworkspace" file and press:
Command + Shift + K
➼ and then:
Command + B
It should work now
Cheers!

try to latest updated install alamofire and also check u use alamofire latest is this in your xcode supported.
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!
target '<Your Target Name>' do
pod 'Alamofire', '~> 4.4'
end
try this above alamofire on your podfile

Answer 9

I had the same issue, the reason was that I installed the wrong version of alamofire.
I am using Xcode 7.3, swift 2.2, so alamofire 3.0 worked for me
remove the library using these steps mentioned by #Michal
Remove or uninstall library previously added : cocoapods
Then in your pod file
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, ‘9.3’ <-- your target version
use_frameworks!
target ’<your target name>’ do
pod 'Alamofire', '~> 3.0’
end

Answer 10

No such module 'Alamofire' Error
because you have not installed the Alamofire in your pod file
open Podfile and add this line
pod 'Alamofire'
double-check in Podfile if this line already is written then no need to write. then just update pod file
for updating your pod open your Podfile into terminal and dial
pod update
