Per Apple's new distribution requirements I need XCode 11 and SDK 13 to release a new version of an app but to get those I need an iOS upgrade to 10.14 which doesn't exist! I'm told by Apple support that I am out of luck and the machine is not updateable any longer. I have to toss the machine as a dev environment. Any ideas how I can make this work?
I'm running a 13" Mac Mid-2010; High Sierra 10.13.6; XCode 10.1; NVIDIA GeForce 320M 256 MB graphics card; 500 GB SSD; 4 GB Ram. Its in top shape and plenty powerful enough to develop apps on.
I ran an update check and checked the iOS documentation. Everything is up to date and there is not any pending update for iOS. XCode has a pending update but it shows incompatible with the current OS version.
