我们的应用程序使用 CoreNFC 来扫描 NFC 标签，如果不支持 NFC，您可以使用 QR。这工作得很好，我们能够在模拟器中运行该应用程序以进行 (ui) 测试。
直到 Xcode12 / iOS14 GM 构建。在 iOS13（或更低版本）中，我们在模拟器上运行它不会有任何问题。

但是在 iOS14 模拟器 iPhone11 上运行它的 Xcode12 中，我们会得到以下结果：

模拟器崩溃对我来说很有意义，因为模拟器无法扫描 NFC 标签，但这就是我所做的：

• 我已经链接到 CoreNFC 框架并使它成为可选的，就像这里描述的：Xcode 10, Swift 4 app with CoreNFC crashes in review on iOS 12
• 放在#if canImport(CoreNFC)周围import CoreNFC …

我CoreNFC sample在Xcode 9.0 beta 2中运行代码时遇到此错误并且应用程序崩溃

dyld: Library not loaded: @rpath/CoreNFC.framework/CoreNFC

  Reason: image not found

有谁知道如何解决这个问题？

Core NFC可以在iPad上运行吗？

总而言之,iPad确实有NFC芯片,但Core NFC文档并没有说它支持它.

注意

iPhone 7和iPhone 7 Plus支持读取NFC NDEF标签.

在模拟器上运行此iOS11-NFC示例将始终Feature not supported在所有设备上运行.
