Lost all IOS Simulator

PierreSavardPierreSavard CAMember ✭✭

Hi experts!
I am new in the wonderful world of Xamarin. Yesterday, I Install Xamarin on my VS2017 and on my Mac Mini installed no ElCapitan (10.11.3). Then I compile the basic template "Welcome to xamarin forms". Selecting IphoneSimulator I got several simulator available (Iphone, Ipad, ...) But when running the code I got an error asking me to upgrade XCode to version 8.3 min (Avalaible only with Sierra OS).
So today I reinstall the Mac mini with Sierra (10.12.6) then reinstall Xamarin and XCode 9. I reconnect the Mac Agent in VS2017 and all working but now I do not have any simulator in the IOS project. I select: Debug->IphoneSimulator->App1.iOS and the only choice are Simulator and Device. When I select Simulator and run the project, I got this error: "Please select a valid device before running the application."

Any suggestion?

    Sorry for the confusion! Unfortunately, you picked an interesting time to jump in and update! A new Xcode 9 was just released by Apple yesterday and we are working on getting compatibility for this out. Keep an eye on for an announcement of support for this version of Xcode 9. Once that is posted you can download the compatible versions.

    Otherwise, you can visit and go to the Downloads section and manually download Xcode 8.3.3 to use with the existing Xamarin tooling you have.

    -_- Wrong timing!
    I uninstall XCode9 and install 8.3.3 and all work good now. Thanks for your help!
