Severity Code Description Project File Line Suppression State
Error Failed to read file attributes for "/Users/admin/Assets.xcassets" Sledi.iOS C:\Program Files (x86)\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets 1028
Hi, I'm having a hard time understand how exactly you got this error. Seems that your asset folder is located in a place where it did not automatically get read rights. It does not seem to be the project default's asset folder.
To help you with this bug, we'd need at least a full verbose build log as well, if possible, as a test case.
I think I experienced the same bug, what fixed it for me was to create (in my case it was missing) the /users/[username]/Library/Caches/Xamarin/Resources folder on my build machine (mac agent) and copy the *.xcassets from my PC containing the project to this new folder.
The bug was originating from the ACTool task failing when it could not find the aforementioned folder.
Verbose build log after deleting the builds folder:
Thanks for providing the build log!
I'm also able to reproduce this in the Cycle 8, SR0 bits in Stable channel.

I was able to reproduce this using 126.96.36.1990 (cycle8/c4382f5) by replicating the directory structure of the solution in the build folder on my Mac agent.
1) Create an iOS app with an asset catalog
2) Build the app while connected to a build agent
3) Navigate to the build folder on the build agent. For me it was:
4) Get the path to the csproj on the Windows machine. For me it was:
5) Replicate that path in the build folder on the Mac agent. It will look like this:
6)Rebuild the project and observe the error:

I was able to verify the fix using 188.8.131.52 (cycle8/b5dcaca) as I was not able to reproduce the error.

Slight typo in comment 11, the tested build was actually 184.108.40.206
220.127.116.11 is the build where the fix was introduced
Adjusting target milestone to Cycle 8 SR 1 for precise bookkeeping based on the verification from Comment 11.
