Answer 1

在瞄准模拟器时似乎是苹果的问题。

您可以使用if targetEnviornment子句包装此代码：

#if !targetEnvironment(simulator)
guard let readFileStream = ArchiveByteStream.fileStream( path: file, mode: .readOnly, options: [ ], permissions: FilePermissions(rawValue: 0o644)) else { return }
#else
fatalError("Apple Archive isn't supported on simulator https://developer.apple.com/forums/thread/665465")
#endif
