When trying to submit my app to the app store i'm getting and SDK version Issue:
ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS 12.0 SDK. All iOS apps submitted to the App Store must be built with the iOS 11 SDK or later, included in Xcode 9 or later. Further, starting March 2019, all iOS apps submitted to the App Store must be built with the iOS 12.1 SDK or later, included in Xcode 10.1 or later."
I'm using IntelliJ with Flex 4,16.1 and Air SDK 32
Any help would be much appreciated
