Swift 2 to Swift 3

Question

In Swift 2 I was able to write this statement:

var reachability = SCNetworkReachabilityCreateWithName(kCFAllocatorDefault, "www.apple.com").takeRetainedValue()

In Swift 3 now it says that SCNetworkReachability? has no member takeRetainedValue().

Answer 1

只需删除不再需要的takeRetainedValue（）即可。

var reachability = SCNetworkReachabilityCreateWithName(kCFAllocatorDefault, "www.apple.com")
