 ## iOS specific steps
 
-- Add targets
+- Install rust 1.46.0 with MacOSX binary support
 
 ```
-rustup target add x86_64-apple-ios aarch64-apple-ios
+wget https://github.com/getditto/rust-bitcode/releases/download/v1.46.0/rust-ios-arm64-1.46.0.zip
+unzip rust-ios-arm64-1.46.0.zip
+cd rust-ios-arm64-1.46.0
+./install.sh
 ```
 
+As the binaries are not signed, you'll have to convince MacOSX that it's safe to run them.
+One solution is to do the following:
+
+1. `cd rust_android_ios/ios_app`
+2. `cargo +ios-arm64-1.46.0 build --target aarch64-apple-ios --release --lib`
+3.a. if it fails because MacOSX doesn't trust the binary, go to 
+   `System Preferences -> Security & Privacy` and `Allow to run binary`
+    then go to 2.
+3.b. if it fails with another error, ask Google
+3.c. if it compiles, go on
+
 - Run the project in Xcode. This will build Rust, put the binaries in the correct place and start the app.
