+2. Right-click on the **Project Name** in the **Solution Explorer**, select **Properties**.
+3. Navigate to the **iOS Build** tab and set **Configuration** to **Release** and **Platform** to **iPhone**.
+4. To build with a specific iOS SDK, select it from the **SDK Version** list. Otherwise, leave this value at **Default**.
+5. Linking reduces the overall size of your application by stripping out unused code. In most cases, **Linker Behavior** should be set to the default value of **Link Framework SDKs only**. In some situations, such as when using some third-party libraries, it may be necessary to set this value to **Don't Link** to ensure that needed code is not removed. For more information, refer to the [Linking Xamarin.iOS apps](~/ios/deploy-test/linker.md) guide.
+6. Check **Optimize PNG images** to further decrease your application's size.
+7. Debugging should not be enabled, as it will make the build unnecessarily large.
+8. For iOS 11, select one of the device architectures that supports **ARM64**. For more information on building for 64-bit iOS devices, please see the **Enabling 64-Bit Builds of Xamarin.iOS Apps** section of the [32/64-bit platform considerations](~/cross-platform/macios/32-and-64/index.md) documentation.
+9. You may wish to use the **LLVM** compiler to build smaller and faster code. However, this option increases compile times.
+10. Based on your application's needs, you may also wish to adjust the type of **Garbage Collection** being used and set up for **Internationalization**.
+
+    After setting the options described above, your build settings should

+13. For **Provisioning Profile**, select the App Store provisioning profile [created above](#create-and-install-an-app-store-provisioning-profile).

 4. To find the .ipa file on the Windows machine, right-click on the Xamarin.iOS project name in the Visual Studio 2019 or Visual Studio 2017 **Solution Explorer** and choose **Open Folder in File Explorer**. Then, in the just-opened Windows **File Explorer**, navigate to the **bin/iPhone/Release** subdirectory. Unless you have [customized the .ipa file output location](#customize-the-ipa-location), it should be in this directory.
 5. To instead view the .ipa file on the Mac build host, right-click the Xamarin.iOS project name in the Visual Studio 2019 or Visual Studio 2017 **Solution Explorer** (on Windows) and select **Show IPA File on Build Server**. This will open a **Finder** window on the Mac build host with the .ipa file selected.
