A tutorial for using Rust with Swift on iOS (Sep 2019)

dw2019rust's Issues

Please update the tutorial

Please update the tutorial and revise the "Automated Build" section to use the cargo-lipo tool instead.

This will result in fewer steps and a simpler process.

And here is my template.

Compiling error from Xcode

When I try to build my framework from Xcode IDE, I alwary meeting = note: ld: library not found for -lSystem error.
So I have to build it from Terminal typing command line by line, and this time there have no error happened any more.
How do I resolve this issue?

I followed this article https://github.com/thombles/dw2019rust/blob/master/modules/04%20-%20Build%20automation.md

Here is my project https://github.com/ShadowsocksR-Live/overtls#building-ios-framework-1

How can I trigger swift function from Rust?

I have one idea about solving. It is creating a bool value in swift and giving its address to Rust. Then setup a timer in swift and check the bool value continuously. When it's time, change value of bool from its address in Rust and it will trigger the function. This scenario could work? How can I solve this problem in efficient way?

Secondly, is there any original type of bitmap in rust? I've seen many crates. Which one do you recommend?

Giving some errors while checking run compatibility for c and swift on m1 mac

I've followed the guide but it gives this output with command
nm target/debug/libanvil.a | grep hello

0000000000000000 T _hello_devworld
target/debug/libanvil.a:rustc_std_workspace_alloc-9cf27ed549592a86.rustc_std_workspace_alloc.9703e405-cgu.0.rcgu.o: no symbols

target/debug/libanvil.a:rustc_std_workspace_core-b5600cb14c277fae.rustc_std_workspace_core.3407a808-cgu.0.rcgu.o: no symbols

I ignored it but when I run with iOS app it gives this error

Undefined symbols for architecture arm64:
  "_hello_devWorld", referenced from:
      ExampleRustApp.ViewController.viewDidLoad() -> () in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've installed rust with rustup instead of homebrew. My rustup show command give this output
