iCepa: Building the project fails

I tried building the project but it fails with these errors:

• iCepa-master/iOS/ViewController.swift:21:9: Type ‘NETunnelProviderManager’ has no member ‘loadOrCreateDefaultWithCompletionHandler’
• could not find Cargo.toml in iCepa-master/Extension/tun2tor or any parent directory fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: can’t open input file: target/x86_64-apple-ios/debug/libtun2tor.a (No such file or directory)

I have followed the exact steps mentioned in README.
