Goals

The Facebook SDK must also be built successfully in Unity.

Expected results

Adding the Facebook SDK to Unity and exporting it to Xcode should not result in a build failure.

Actual results

After adding the Facebook SDK to Unity and exporting it to Xcode, the build fails. The build failure is due to the Facebook SDK's Validation Failed. (Validation Error: A sealed resource is missing or invalid).

The reason for the Validation Failed error is as follows: There is a build issue due to the symlink while applying the FacebookSDK_Dynamic.xcframework.zip file.

Symlinks have been identified in the folders and files under the following XCFrameworks:

• FBAEMKit.xcframework/ios-arm64_x86_64-maccatalyst/FBAEMKit.framework
• FBSDKCoreKit_Basics.xcframework/ios-arm64_x86_64-maccatalyst/FBSDKCoreKit_Basics.framework
• FBSDKCoreKit.xcframework/ios-arm64_x86_64-maccatalyst/FBSDKCoreKit.framework
• FBSDKGamingServicesKit.xcframework/ios-arm64_x86_64-maccatalyst/FBSDKGamingServicesKit.framework
• FBSDKLoginKit.xcframework/ios-arm64_x86_64-maccatalyst/FBSDKLoginKit.framework
• FBSDKShareKit.xcframework/ios-arm64_x86_64-maccatalyst/FBSDKShareKit.framework

Adding these XCFrameworks to the Unity engine will break the symlinks. (The file copying provided by the Unity Engine does not preserve symlinks.) In this state, performing a Unity Build will result in a Validation Failed error for the Facebook SDK in Xcode. (Validation Error: A sealed resource is missing or invalid).

XCFramework added to Unity

The FacebookSDK-Static_XCFramework.zip does not have symlinks, so this issue does not occur.
