Extension function is inaccessible due to 'internal' protection level

Question

So I have this lovely extension that would allow me to write conditional view modifiers to my views, made by Antoine van der Lee https://www.avanderlee.com/swiftui/conditional-view-modifier/. The problem I'm running into is that it is inaccessible because of 'internal' protection level, even though I have set the extension AND the function public. Any ideas how to fix this that doesn't involve pasting it to all the files.?

import SwiftUI

public extension View {
    
    /**
     Applies the given modifier if the given condition evaluates to `true`.
     
     - Parameters:
        - condition: The condition to evaluate.
        - transform: The modifier to add to the source `View`.
     - Returns: Either the original `View` or the modified `View` if the condition is `true`.
     */
    @ViewBuilder
    public func `if`<Content: View>(_ condition: @autoclosure () -> Bool, transform: (Self) -> Content) -> some View {
        if condition() {
            transform(self)
        } else {
            self
        }
    }
    
}

The extension is also in it's own package that is being imported to the package with my views.

Usage in code:

Text("Hello, world!")
            .padding()
            .if(image != nil) { view in
                view.padding()
            }
