Tutorial Xcode 6: Resolving Symbol Not Found Error on arm64 Architecture

In this tutorial, we will explore a common issue faced by developers when building apps for both Android and iOS using SDL 2.0. Specifically, we will tackle the error 'symbol(s) not found for architecture arm64' and its relation to the Xcode 6 environment.

The Problem

When trying to run an app on a physical iPhone 6 device, you may encounter the following error:

`Ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

_METLCreateSystemDefaultDevice`, referenced from:

_OBJC_CLASS$_MTLRenderPipelineDescriptor`, referenced from:

_OBJC_CLASS$_MTLRenderPassDescriptor`, referenced from:

_OBJC_CLASS$_MTLSamplerDescriptor`, referenced from:

_Objc-class-ref in libSDL2.a(SDL_render_metal.o)`

This error is caused by the absence of certain symbols required for architecture arm64. In this tutorial, we will explore how to resolve this issue and get your app running smoothly on both Android and iOS devices.

Solution

To fix this error, follow these steps:

1. Ensure 'Build for Other Architectures' is Enabled: Open your project settings and ensure that the 'Build for Other Architectures' setting is enabled.

2. Add arm64 to Architectures List: In your target's build settings, add arm64 to the architectures list.

Additional Troubleshooting

If you are still facing issues after implementing these steps, check the following:

* Ensure that your project is configured correctly for iOS development.

* Verify that all necessary frameworks and libraries are included in your project.

* Check for any conflicts with other architectures or settings in your project.

By following this tutorial, you should be able to resolve the 'symbol(s) not found for architecture arm64' error and successfully build and run your app on both Android and iOS devices using SDL 2.0 and Xcode 6.

In conclusion, resolving the 'symbol(s) not found for architecture arm64' error in Xcode 6 requires a combination of enabling 'Build for Other Architectures', adding arm64 to the architectures list, and ensuring proper project configuration. By following these steps, you can successfully build and run your app on both Android and iOS devices using SDL 2.0 and Xcode 6. Happy coding!
