iOS + ZeroTier SDK

Welcome!

Imagine a flat, encrypted, no-configuration LAN for all of the instances of your iOS app.

This short tutorial will show you how to enable ZeroTier functionality for your iOS app with little to no code modification. Check out our ZeroTier SDK page for more info on how the integration works.

---

Step 1: Build iOS framework

• make ios_app_framework
• This will output to build/ios_app_framework/Release-iphoneos/ZeroTierSDK_iOS.framework

Step 2: Integrate SDK into project

• Add the resultant framework package to your project
• Add src directory to Build Settings -> Header Search Paths
• Add build/ios_app_framework/Release-iphoneos/ to Build Settings -> Framework Search Paths
• Add ZeroTierSDK.frameworkiOS to General->Embedded Binaries
• Add src/ZTSDK.swift, src/SDK_XcodeWrapper.cpp and src/SDK_XcodeWrapper.hpp to your project:
• Set src/SDK_Apple-Bridging-Header.h as your bridging-header in Build Settings -> Objective-C Bridging-header

Step 3: Start the ZeroTier service

Start the service:

    zt.start_service(nil);
    zt.join_network(nwid);

Listen for incoming connections:

    let sock: Int32 = zt.socket(AF_INET, SOCK_STREAM, 0)
    let ztaddr: ZTAddress = ZTAddress(AF_INET, serverAddr, Int16(serverPort))
    let bind_err = zt.bind(sock, ztaddr)
    zt_listen(sock, 1);
    let accepted_sock: Int32 = zt.accept(sock, ztaddr)

Or, establish a connection:

    let sock: Int32 = zt.socket(AF_INET, SOCK_STREAM, 0)
    let ztaddr: ZTAddress = ZTAddress(AF_INET, serverAddr, Int16(serverPort))
    let connect_err: Int32 = zt.connect(sock, ztaddr)
