Grab a coffee, because you'll be here for a while. By default this builds OpenCV for 8 architectures across 4 platforms:

The script has some configuration options to exclude platforms and architectures you don't want to build for. Use the `--help` flag for more information.
## How it Works
This script generates a fat `.framework` for each platform you specify, and stitches them together into a `.xcframework`. This file can be used to support the same architecture on different platforms, which fat `.framework`s don't allow. To build the intermediate `.framework`s, `build_xcframework.py` leverages the `build_framework.py` scripts in the ios and osx platform folders.
### Passthrough Arguments
Any arguments that aren't recognized by `build_xcframework.py` will be passed to the platform-specific `build_framework.py` scripts. The `--without` flag mentioned in the examples is an example of this in action. For more info, see the `--help` info for those scripts.
## Examples
You may override the defaults by specifying a value for any of the `*_archs` flags. For example, if you want to build for arm64 on every platform, you can do this:
If you want to build only for certain platforms, you can supply the `--build_only_specified_archs` flag, which makes the script build only the archs you directly ask for. For example, to build only for Catalyst, you can do this:
You can also build without OpenCV functionality you don't need. You can do this by using the `--without` flag, which you use once per item you want to go without. For example, if you wanted to compile without `video` or `objc`, you'd can do this:
```
python build_xcframework.py --out somedir --without video --without objc
```
(if you have issues with this, try using `=`, e.g. `--without=video --without=objc`, and file an issue on GitHub.)
