Hi. The editor is now able to checkout the file but the only reason it does it is to change the line ending character encoding. It does it even with Perforce workspace's line ending setting is set to UNIX. That is the only thing that change in the file (it does that for other settings files too).

Resolution Note (fix version 2019.2):
XRSettings.asset is a serialized ScriptableObject, but because it's in PackageSettings we couldn't use Asset Database to handle serialization. That means we were not getting the benefit of it's integration with the Provider system. This means that we were always trying to write to a locked file if Perforce were enabled.
The change here is to add a call to the Provider to ask for check out permissions. This should unlock the file if allowed. We also check for Read Only state after that to make sure we aren't trying to write to a file that may be manually locked.
