Question

so I updated their by cocoapods and I fixed all my project issues, after all that I got this error about Alamofire

The following binaries use incompatible versions of Swift:

also I have these warnings

this is my pod file

this what I see in terminal after pod update

CocoaPods 1.2.0.beta.1 is available.
To update use: `sudo gem install cocoapods --pre`

[!] The `ehtamiApp [Debug]` target overrides the `EMBEDDED_CONTENT_CONTAINS_SWIFT` build setting defined in `Pods/Target Support Files/Pods-ehtamiApp/Pods-ehtamiApp.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.
