Wasm3 running on iPhone 8
Install Xcode, then open and build the project as usual.
**Note:** Xcode runs apps in `Debug` mode by default. Select `Release` mode for significantly better performance.
You can also build the project from command line:
```sh
xcodebuild build -scheme wasm3 -project wasm3.xcodeproj -configuration Release -destination 'platform=iOS Simulator,name=iPhone 11,OS=13.3'
```
