我的代码snipet如下…：
let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
SCNetworkReachabilityCreateWithAddress(nil,UnsafePointer($0))
}
…不再编译与以下错误，我不明白：
"'init' is unavailable: use 'withMemoryRebound(to:capacity:_)' to temporarily view memory as another layout-compatible type."
如何解决它？
从Xcode 8 beta 6的发行说明：
@H_502_14@An Unsafe[Mutable]RawPointertype has been introduced,replacingUnsafe[Mutable]Pointer<Void>. Conversion fromUnsafePointer<T>to
UnsafePointer<U>has been disallowed.Unsafe[Mutable]RawPointer
provides an API for untyped memory access,and an API for binding
memory to a type. Binding memory allows for safe conversion between
pointer types. SeebindMemory(to:capacity:),assumingMemoryBound(to:),
andwithMemoryRebound(to:capacity:). (SE-0107)
在你的情况下，你可能需要这样写：
let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
$0.withMemoryRebound(to: sockaddr.self,capacity: 1) {zeroSockAddress in
SCNetworkReachabilityCreateWithAddress(nil,zeroSockAddress)
}
}
