Alamofire - not be code signed because its settings don't specify a development team in Xcode 8

Question

I hit the error on below on Xcode 8, can everyone help to solve it. My application need to support iOS 8 and above.

Alamofire will not be code signed because its settings don't specify a development team. “Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

Thanks

Answer 1

What did it for me with the updated Alamofire and Xcode 8 is the following:

1) Open your project via the <yourproject>.xcworkspace file

2) Go to Pods -> Targets -> Alamofire -> Build Settings and set the following property:

I think it has to do with the fact that the new Alamofire 4.0 was a pretty big update due to Swift 3/Xcode 8. I haven't had the error before updating.

PS The first part "Alamofire will not be code signed because its settings don't specify a development team." of your error message seemed like a separate thing in my case, which either got solved because I did pod install a few times until Alamofire actually got updated or because of the setting that I mentioned above. Either way both things cleared out for me.

Add this to the end of your Podfile to set the build configurations for each pod to use the latest version of Swift:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.0'
    end
  end
end
