| **Architecture**         | Select the CPU to build for (only applies to Build And Run).* **Intel 64-bit**: Use Intel/AMD 64-bit CPU architecture.- **Apple Silicon**: Use Apple's Silicon architecture.
- **Intel 64-bit + Apple Silicon**: Use both architectures.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             |
| **Create Xcode Project** | Enable this setting to generate an Xcode project so you can build your final application bundle in Xcode. Xcode has built-in support for code signing and uploading the application to the Mac App Store.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
| **Run in Xcode as**      | Select whether Xcode runs your Project as a **Release** or **Debug** build.* **Release**: Builds an optimized version of your app.- **Debug**: Builds a testing version of your app that contains additional code that helps with debugging.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |
| **Compression Method**   | Specifies the method Unity uses to compress the data in your Project when it builds the Player. This includes [Assets](/engine/6000.3/manual/assets-and-media/asset-types/assets-supported-types.md.md), [Scenes](/engine/6000.3/manual/working-with-scenes/creating-scenes.md.md), [Player settings](/engine/6000.3/manual/unity-editor/editor-settings-reference/comp-manager-group/class-player-settings.md.md), and [GI data](/engine/6000.3/manual/lighting-overview/direct-and-indirect-lighting/lightmap-data/gicache.md.md).* **Default**: On Windows, Mac, Linux Standalone, and iOS, there's no default compression. On Android, the default compression is ZIP, which gives slightly better compression results than LZ4HC. However, ZIP data is slower to decompress.* **LZ4**: A fast compression format that is useful for development builds. For more information, refer to [BuildOptions.CompressWithLz4](/engine/6000.3/script-reference/unityeditor/buildoptions/compresswithlz4.md.md).- **LZ4HC**: A high compression variant of LZ4 that is slower to build but produces better results for release builds. For more information, refer to [BuildOptions.CompressWithLz4HC](/engine/6000.3/script-reference/unityeditor/buildoptions/compresswithlz4hc.md.md). |
