I need to automate updating to latest iOS betas as part of my ci script, but I can't get it to install iOS 26.0 beta for the life of me, using xcodes or xcodebuild.
I can see the version listed using xcodes runtimes --include-betas, and I tried sudo xcodes runtimes install "iOS 26.0-beta1", but I would get the error
Downloading Runtime iOS 26.0-beta1: 0%
Error: ProcessExecutionError()\
I also tried xcodebuild -downloadPlatform iOS -buildVersion 23A5260l, where I found the specific build id on apples dev images website. But I would get the error
iOS 23A5260l is not available for download. Specific version download failed, trying downloadPlatform ios latest...
And similar error for trying xcodebuild -downloadPlatform iOS -buildVersion 26.0 or other version ids I found online. But this command would work for any other versions and betas listed on the website.
I was able to install iOS 26.0 through xcodebuild -downloadPlatform iOS, which automatically installed it for me, but this is unideal for my situation, as I want to control which betas to install instead of just the latest one (like iOS 18.6 beta that just came out).
Is anyone else also struggling with these errors?
xcodes version 1.6.2 Xcode version 26.0 Beta (installed and selected through xcode)
