+## Building for iOS
+
+See [this guide](https://blog.mozilla.org/data/2022/01/31/this-week-in-glean-building-and-deploying-a-rust-library-on-ios/)
+for detailed instructions on compilation for iOS.
+
+All scripts are run from this directory.
+
+For iOS devices:
+
+```bash
+ARCHS=arm64 ./comiple-ios.sh cozo_c release
+```
+
+For simulator on Apple ARM:
+```bash
+IS_SIMULATOR=1 ARCHS=arm64 ./comiple-ios.sh cozo_c release
+```
+
+For simulator on x86-64:
+```bash
+IS_SIMULATOR=1 ARCHS=x86_64 ./comiple-ios.sh cozo_c release
+```
+
+The libraries are then found in `../target` subdirectories. The static libraries can then be linked into
+your iOS applications.
