Hello, we are trying to upload an iOS app made with Pubcoder to the App Store Connect to test it with Testflight. We have exported succesfully the .ipa file but when trying to upload it with Transporter it shows the following error message:
ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS 13.7 SDK. All iOS apps submitted to the App Store must be built with the iOS 14 SDK or later, included in Xcode 12 or later.
We are using a MacBook Pro with macOS Big Sur 11.2.3, Xcode 12.5 and Pubcoder 3.11. Is there anything we can do to fix this or is this something that has to be changed in Pubcoder?
