Module 'Alamofire' has no member named 'request'

if you are using new Alamofire 5.xxx then you will use AF instead of Almofire it like that

AF.upload(multipartFormData: <#T##(MultipartFormData) -> Void#>, to: <#T##URLConvertible#>)

AF.request(<#T##url: URLConvertible##URLConvertible#>)

AF.download(<#T##url: URLConvertible##URLConvertible#>)

Alamofire.xcodeproj -> Build Phases -> Complie Sources

If (0 item), then "[+] Alamofire.swift".

It's OK :)

2019 UPDATE

If you have this error and you use 'alamofire5' branch just change Alamofire.request to AF.request.

I solved this issue by changing the Build Active Architectures Only settings.

Click on your project in the Project Explorer, select Build Settings, locate Architectures section, and change the Build Active Architecture Only setting to Yes for Debug and No for Release.

Hope this will work for you.
