I installed Xcode beta 11 and kept the 10.2 version, I submit my apps for review but I get invalid binary even though I did build with Xcode 10.2. I even uninstalled Xcode 11 beta and the same thing. I have no idea what to do next
ITMS-90111: Invalid Toolchain - Your app was built with a beta version of Xcode or SDK. Apps submitted to the App Store must be built with the GM version of Xcode 9 and the SDK for iOS 11, tvOS 11, watchOS 4, or macOS 10.13 or later.
Upload App With OS Beta
Don't use Xcode beta
Archive the app; before start upload go
Right click in your app
Will open the folder and you go right click in your app and select
Now you will find the pList to change info
Finally will change your BuildMachineOSBuild
Find the BuildMachineOSBuild and change to build Mojave ( January 22, 2019 )
The answer to this question was provided by Warren (aka dodgio) on the Apple Developer Forums:
App needs to be compiled with release version of Xcode, wait for GM(Golden Master) version.
