 ### To build Pax projects as native macOS apps
 
 - Building macOS apps requires running a Mac with macOS.  This is a constraint enforced technically and legally by Apple.
-- Install xcode `>=14.3` and Xcode command line utils: `xcode-select --install`
-- SDK Version `macosx13.3`, Xcode version `>=14.3`
+- Install xcode `>=15.0` and Xcode command line utils: `xcode-select --install`
+- Make sure to accept Xcode's license agreement (prompted during Xcode startup for the first time)
+- SDK Version `macosx13.3`, Xcode version `>=15.0`
 - Current Minimum Deployment `13.0`
+- Install all necessary build architectures for Rust, so that binaries can be built for both Intel and Apple Silicon macs
+  ```
+  rustup target add aarch64-apple-darwin x86_64-apple-darwin

+### To build Pax projects as native iOS apps
+
+- Follow instructions for building native macOS apps, above
+- Install all necessary build architectures for Rust, so that binaries can be built for iOS and simulator targets:
+  ```
+  rustup target add aarch64-apple-ios x86_64-apple-ios aarch64-apple-ios-sim
+  ```
+- Install [ios simulator through Xcode](https://developer.apple.com/documentation/safari-developer-tools/adding-additional-simulators)
