Xamarin iOS : Build apps with error - One or more errors occurred

I'm using Visual Studio 2017 version 15.9.15 on Windows10. Today I try build and deploy my iOS project, with no reason I get error message - One or more errors occurred . When I click on the error message, it brings me to this line of code
<CopyFilesToBuildServer SessionId="$(BuildSessionId)" Files="@(_CopyFilesToMacOutput);@(_NoneWithCopyToOutputDirectory)" />.
This error only happened when I select Debug mode, Release mode worked good.
I really lack of ideas what had happened, can anyone give me some advice?

    End up I resolve the issues by :
    (1) updates Visual Studio 2017 to version 15.9.17
    (2) repair Visual Studio 2017
    (3) clone again my project into different folder
    (4) Build and run the project

    Is it happening over device and simulators or only on either one of those?

  • WeiLoonWongWeiLoonWong USMember ✭✭

    It's happened on devices. I'm using iPhoneX (iOS 13.1.1)

    1. Try to update visual studio to 2019 .

    2. Ensure you've selected Don't Link on Linker Behavior in project configuration.

    @ColeX I changed link behavior to Don't Link but no luck.
    And so far we have no plan to migrate to Visual Studio 2019 yet. Fyi, my colleague with same version of Visual Studio 2017 able to build and deploy iOS project. Do you have any ideas?

    Try to reinstall vs or create a blank project and move you file into it one by one to figure out the cause .
