Which module should i import when i using CFSocket?

Question

Hi all,

Which module should i import when i using CFSocket in swift?

For most uses of this API, you will need to include three headers:

#import <CoreFoundation/CoreFoundation.h> #include <sys/socket.h> #include <netinet/in.h>

But when i paste this line to Xcode, there's 5 Errors!!!

Am i missing something? What's the correct module?

What are you using

CFSocket

for? It’s probably not the droid you’re looking for. Specifically:

If you’re looking to make outgoing TCP connections, you should use
```
NSStream
```
If you’re listening for incoming TCP connections, use
```
NSNetService
```
for the listening part and
```
NSStream
```
for handling the connection
If you’re looking to do low-level stuff, like UDP, it’s best to use BSD Sockets, employing dispatch if you need async support

Share and Enjoy
