> It sounds like you're trying to link against an older Swift runtime while targeting a newer OS.

It turns out that at the Project level, not the Target level, someone had defined:

```swift
LIBRARY_SEARCH_PATHS = (
					"\"$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)\"",
					"\"$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)\"",
					"\"$(inherited)\"",
				);

```

🤦‍♂️

After removing that, and making sure everything is targeting iOS 13.5, the error has gone away. Thanks for your help Joe 👍
