swift - "Session Failed - probably due to lack of camera access"Xcode错误

Question

我遵循了本教程:https://www.raywenderlich.com/378-augmented-reality-and-arkit-tutorial了解增强现实。

当我运行项目时出现错误:

 Session did fail with error: Error Domain=com.apple.arkit.error Code=100 "Unsupported configuration." UserInfo={NSLocalizedDescription=Unsupported configuration., NSLocalizedFailureReason=The provided configuration is not supported on this device.} Session Failed - probably due to lack of camera access.   

即使我使用以下代码进行测试以验证模拟器是否支持 ARKit，我也没有找到此错误的原因:

 if (ARConfiguration.isSupported) {
 print("ARKit is supported. You can work with ARKit")
  } else {
    print("ARKit is not supported. You cannot work with ARKit")
  }

可能是什么问题？

Answer 1

if ARConfiguration.isSupported {
    print("ARKit is supported. You can work with ARKit")
} else {
    print("ARKit is not supported. You cannot work with ARKit")
}

这个 ARConfiguration.isSupported 实际上并没有表明你运行你的应用程序的设备(或模拟器)是否能够使用世界跟踪或类似的东西(这是很多 AR 所必需的)特征)。

您可能想检查一下 ARConfiguration支持子类...例如这个 ARWorldTrackingConfiguration

if ARWorldTrackingConfiguration.isSupported { ... }

无论如何，这并不能解决出现错误的问题，如果您想测试您的 AR 应用，您必须在真实设备上运行您的应用。
