I have this issue when I tried to test with iOS device.The debug configuration with Build Active Architecture Only is set to NO. After I set to YES, I can test with my iPhone. 
This will resolve the issue surely.
当我尝试使用 iOS 设备进行测试时，我遇到了这个问题。使用 Build Active Architecture Only 的调试配置设置为 NO。在我设置为 YES 后，我可以用我的 iPhone 进行测试。这肯定会解决问题。

Maybe the issue because of a third party SDK integrated into your project using Cocoapods. do the following:
问题可能是因为使用 Cocoapods 将第三方 SDK 集成到您的项目中。请执行下列操作：
- Clear
derived data& restartXcode. - Clean & Build.?
- 清除
derived data并重新启动Xcode。 - 清洁和建造。？
Or if you don't mind disabling bitcode: Go to build settings search bitcode and change "Enable Bitcode" to "No".
或者，如果您不介意禁用位代码：转到构建设置搜索位代码并将“ Enable Bitcode”更改为“ No”。

The problem might be with lAVCtrl_armv7third party library, you can confirm this by editing valid Architecture to arm64and re-compile.
问题可能出在lAVCtrl_armv7第三方库上，您可以通过将有效架构编辑为arm64并重新编译来确认这一点。
