**Additional Information:**

   This was not an issue in previous XS/XI versions. 
   It was discovered when a user has some files in source control which would make them read-only. It could be related to the Root.plist file too. It could also be similar to previous bugs where some files that are copied to the obj are not made writable (remove read-only). e.g. http://forums.xamarin.com/discussion/25489/copyandconvertresources-task-failed-unexpectedly-read-only-resources

I did some testing and this error does _not_ occur with Mono, even with the other C8 bits installed.
Comment 4 Alex Soto [MSFT] 2016-09-22 13:48:31 UTC
I can also dupe this error using latest xamarin-macios/master @ 351bb29f0c56f688dd078be50b3b811ccb1c07ca
Comment 5 Sebastien Pouliot 2016-09-22 14:54:59 UTC
Sounds like a change in mono exposed this. Still if we copy a file the destination is "ours" and should be writable.
Comment 6 Jeffrey Stedfast 2016-09-26 19:00:45 UTC
Mono's xbuild Copy task seems to be duplicating file permissions from the source file.

There's an argument to be made on both sides of this, but given that there's no reason for output files to ever be read-only and that Mono broke behavior, I'd argue for punting this over to the Mono team.

It'll be ridiculous for us to have to chmod every file we may want to modify from any of the tasks before we try to open the file. That's just insane.
Comment 7 Ankit Jain 2016-11-01 20:08:52 UTC
Are you sure that the issue is in xbuild's Copy task? Last commit to that file was in Feb 2015. BTW, which file is this failing on?

Also, how do I reproduce this? I tried with latest from the Stable channel:

Mono 4.6.1 (mono-4.6.0-branch-c8sr0/ef43c15) (64-bit)
Xamarin.iOS Version:

.. but it builds fine from XS and from command line (`$ xbuild`).

Logs show the relevant target running successfully.

                        Target _CreateDebugSettings:
                                CreateDebugSettings Task
                                  AppBundleDir: bin/iPhoneSimulator/Debug/SettingsTest.iOS.app
                                  DebuggerPort: 10000

C9 is now closed. We'll move this bug to the next scheduled milestone, "15.1". We'll continue working on these issues, and will attempt to resolve them ASAP.
Comment 9 Ankit Jain 2017-03-21 18:04:32 UTC
@Alex, since you were able to reproduce this (https://bugzilla.xamarin.com/show_bug.cgi?id=44583#c4), could you please check if you can reproduce this with latest stable too?
Comment 10 Alex Soto [MSFT] 2017-03-23 20:43:53 UTC
@Ankit I cannot reproduce this issue anymore using latest xamarin/macios/master @ 272a5ef53e065944d1ca867753f685493a9ff687
Comment 11 Ankit Jain 2017-03-23 20:45:56 UTC
Closing this based on Alex's latest comment.
