Pull request overview

This PR fixes Hot Reload (HR) functionality on iOS by disabling the linker/trimmer when the RemoteControl package is referenced. The trimmer was removing HR messages and reflection metadata required for Hot Reload to function properly. The fix adds MSBuild logic to automatically set linker modes to 'None' for iOS and Android, with warning messages if developers manually override these settings.

Key Changes

• Adds <Choose> block to automatically disable linking on iOS (MTouchLink=None) and Android (AndroidLinkMode=None) when not already set
• Adds warning targets that alert developers if linking is manually enabled, as it breaks Hot Reload functionality
• Both changes are conditionally applied only when targeting iOS or Android platforms
