Assertion failedエラー

エラー詳細

Assertion failed: (false && "compact unwind compressed function offset doesn't fit in 24 bits"), function operator(), file Layout.cpp, line 5758.

対策

1. xcodeのBuildSettingで、PROJECT側のUnity-iPhoneの"Other Linker Flag"に"-ld_classic"を追加。

参考：https://developer.apple.com/forums/thread/735426

ちなみに、"-ld64"は非推奨。

PostProcess対応

Assets/Editor/XcodeIdClassicPostProcess.cs

using UnityEditor;
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;

public static class XcodeIdClassicPostProcess
{
    [PostProcessBuild]
    public static void OnPostProcessBuild(BuildTarget target, string path)
    {
        if (target != BuildTarget.iOS)
        {
            return;
        }
        var project = new PBXProject();
        project.ReadFromFile(PBXProject.GetPBXProjectPath(path));
        project.AddBuildProperty(project.GetUnityMainTargetGuid(), "OTHER_LDFLAGS", "-ld_classic");
        project.WriteToFile(PBXProject.GetPBXProjectPath(path));
    }
}
