Check for internet connection availability in Swift

由 最后都变了- 提交于 2019-12-17 02:28:15
问题 Is there a way to check if the internet connection is available using Swift? I know there are many third party libraries to do this but they are all written in Objective-C. I'm looking for a Swift alternative. 回答1: As mentioned in the comments, although its possible to use Objective-C libraries in Swift, I wanted a more pure Swift solution. The existing Apple Reachability class and other third party libraries seemed to be too complicated for me to translate to Swift. I Googled some more and I

So I've replaced the word

looking for alternative solution than IPFW for slowing down an internet connection

问题 I need to slow down (simulate bad) internet connection, I found some documentation where it was achieved by "ipfw pipe" command , the thing is that in latest MAC OS versions , ipfw was deprecated (and removed)... I was wondering if there are any alternative to the ipfw API ? Does anyone know how latest Network Link Conditioner achieves it? The original previous way which enabled to slow down an internet connection : sudo ipfw pipe 1 config bw 56Kbit/s delay 200 plr 0.2 and to clear the pipe :

Right now I am just checking with the Internet connection, using Reachability class. So how to check that? 回答1: You can make use of CNCopySupportedInterfaces() call. CFArrayRef interfaces = CNCopySupportedInterfaces(); CFIndex count = CFArrayGetCount(interfaces); for (int i = 0; i < count; i++) { CFStringRef interface =
