Trying to compile the project http://github.com/aleene/openfoodfacts-ios with Xcode.app 10.2.1 (10E1001), swift 5.0.1; using the Cartfile:

github "Alamofire/Alamofire" >= 4.6
github "tristanhimmelman/AlamofireObjectMapper" >= 4.1.0
github "onevcat/Kingfisher" >= 5.0
github "xmartlabs/XLPagerTabStrip" >= 7.0
github "Tovkal/ImageViewer" >= 0.1.4
github "DaveWoodCom/XCGLogger"
github "Daltron/NotificationBanner"
github "httpswift/swifter" "stable"
github "SVProgressHUD/SVProgressHUD" >= 2.2.1
github "hackiftekhar/IQKeyboardManager" >= 5.0.6
github "kishikawakatsumi/KeychainAccess"

github "SnapKit/SnapKit"
github "scenee/FloatingPanel" >= 1.3.5
github "TimOliver/TOCropViewController"

and after a successful compilation of all those dependencies with:

carthage outdated
carthage update

and a successful compilation of the app in Xcode, cf https://github.com/informatimago/openfoodfacts-ios/tree/upgrades--xcode-10.2.1--swift-5.0.1 I get at run-time:

The occurrences of JSONDecoder are found there:

The strange thing is that there seem to be a recursive carthage checkout: openfoodfacts-ios/Carthage/Checkouts/AlamofireObjectMapper/Carthage/Checkouts/Alamofire

[RomanPodymov]

Hello @informatimago Are you still able to reproduce the issue with AlamofireObjectMapper 6.1.0? If not, please close the issue.

[steelzeh]

This is still happening with AlamofireObjectMapper 6.1.0

Changing the target devices to iOS 13.0 fixed my issue in Xcode
