iOS Build Error

I have a project that I’ve been working on for Android devices, and I’ve started porting it over to iOS. Everything works fine in the editor, but when I go to build and test onto an iOS device, I get this error:

UnityException: Launching iOS project via Xcode failed. Check editor
log for details.
UnityEditor.iOS.PostProcessiPhonePlayer.LaunchInXcode
(System.String buildToolsDir,
System.String buildPath) (at

path, System.String productName,
BuildOptions options) (at
/Users/builduser/buildslave/unity/build/Editor/Mono/BuildPipeline/PostprocessBuildPlayer.cs:141)
UnityEditor.HostView:OnGUI()

And this error:

UnityException: Launching iOS project
via Xcode failed. Check editor log for
details.

I’ve tried launching the build that’s generated directly from Xcode, but that only results in about 200 linking errors:

Does anyone know how to fix this issue? It’s been a huge set back for me and I really appreciate all of the help no I can get.

I’ve actually solved this problem. What I was trying to do was run this in an iOS simulated device, but I found that by editing the sdk used category in the unity player settings so that it was set to simulation sdks rather than device sdks allowed me to launch the project from Xcode and get it running.
