Ios MainPageCollectionViewConrtoller\u setViewDelegate:：发送到实例0x7faa7ae39160的选择器无法识别

我正在编写一个简单的程序，到现在为止，它只应该显示一个简单的uicollectionview。单元格包含标签和图像视图。图像存储在CoreData中。还有一个代码表示没有可用数据的时间。 但这给了我一个错误：

                </collectionViewController>
                <placeholder placeholderIdentifier="IBFirstResponder" id="Ek1-0V-iZ8" userLabel="First Responder" sceneMemberID="firstResponder"/>
            </objects>
            <point key="canvasLocation" x="1256" y="1014"/>
        </scene>

我在这个错误中工作了两天，但我还没有找到解决办法。

请提供帮助。

您可以添加一个符号断点，该断点在发生此情况时停止。5点左右看一看视频。这为您提供了更多的信息。我找不到真正的原因，但通过创建一个具有相同内容的新项目来修复。因此，这可能是项目配置中的一个错误。

请将此简化为一个合理的最小示例
