I get an error when doing carthage update --plaform ios

Here is the cartfile:

github "Alamofire/Alamofire" ~> 4.4
github "ReactiveX/RxSwift" ~>  4.3.1
github "RxSwiftCommunity/RxAlamofire" ~> 4.4.0
github "onevcat/Kingfisher" ~> 3.0
github "patchthecode/JTAppleCalendar" ~> 7.0
github "stripe/stripe-ios"

And the Log error:

error: SWIFT_VERSION '5.0' is unsupported, supported versions are: 3.0, 4.0, 4.2. (in target 'RxAlamofire iOS')

My project use Swift 4.2 and I check on the RxAlamofire github project the 4.4.0 and it's for Swift 4.2.

Does any one have the same issue and know how to solve it?

Remove RXAlamofire version and try again

github "Alamofire/Alamofire" ~> 4.4
github "ReactiveX/RxSwift" ~>  4.3.1
github "RxSwiftCommunity/RxAlamofire"
github "onevcat/Kingfisher" ~> 3.0
github "patchthecode/JTAppleCalendar" ~> 7.0
github "stripe/stripe-ios"

You can also remove the whole first line github "Alamofire/Alamofire" ~> 4.4 since Alamofire is the dependency of RXAlamofire and will be downloaded automatically.

Personal experience : I usually don't specify a specific version unless I have a reason for that.
