ITMS-90111: Invalid Toolchain

Yeah, I'm facing the same problem. I sent 4 different builds to iTunes Connect and each one was rejected.

Happens like clockwork - see: 9.2.16/3.26.19 Xcode 'Invalid Toolchain Error' PSA

I am receiving the same error. Been getting it for 3 days now.

Still the same error. It’s been days.

Still getting this error; any updates?

I am having the same issue. Tried a few quick fixes on the internet, but with no successI was already 5 attempts in before I found this post. Just to be clear. This happens occasionally after a major update and it's just a waiting game for us if we are on the beta software? Thanks!

I am having the same issue currently. Already build multiple times are got multiple rejection.

Still happens to me too and the post https://forums.developer.apple.com/thread/61855 didn't seem to help.

Any updates yet? Still aren't able to upload. I reinstalled XCode, updated multiple drivers and changed minimum deployment iOS without success...

There is a workaround (thanks stackoverflow):

Right after archiving your app, before uploading to the appstore :

• Go to Organizer
• Right-Click on your app archive -> show in Finder
• Right-Click on the .xcarchive -> Show package content
• Go to Products/Applications/"AppName".app/
• Open the info.plist
• Find the BuildMachineOSBuild and change it to the latest public MacOS release (18F132 for macOS 10.14.5)

Go and upvote this kind sir :

A better workaround is to never try and use unsupported beta tools for production builds. Ever. I’ve been in the software business a long time and believe me, having an unstable/unsupported build process always comes back to bite you eventually.

If you need to tinker with beta stuff and have just one Mac, install it on a separate drive. Always keep it isolated from your production setup.

Hey I found a working fix here https://www.youtube.com/watch?v=8XQ29bBCP8M

I had to create virtual machine with Sonoma , install Xcode 15, then from the main machine with Sequoia but running Xcode 15, ( can be the same done in Xcode 16 this part ) create a provisioning profile, export developer profile from Xcode , export the two certificates I saw on my system keychain access regarding to apple developer. On the virtual machine (Sonoma), import the certificates exported from the keychain , add it to System ( not to login ) , in Xcode, import the developer profile, in the App general, instead of Xcode managing the provisioning profile, select to import and select the provision profile you made at developer.apple.com ( be sure to select iOS , on the devices show all and select all Macs and phones.. and everything ;) Then create the Archive, right click + show in finder. copied the xarchive to my sequoia os machine, and upload from there
