  4. See "Enable String Catalog Symbol Generation" warning.
    Image

When I apply the warning LastUpgradeCheck is set to 2600 and STRING_CATALOG_GENERATE_SYMBOLS = YES; build setting is applied.

STRING_CATALOG_GENERATE_SYMBOLS summary:

When enabled, symbols will be generated for manually-managed strings in String Catalogs.

See https://developer.apple.com/videos/play/wwdc2025/225?time=1091.

This build setting did not exist on Xcode 16.
