Cannot call value of non-function type 'ImageResource'

[xiky]

I'm trying to use this repository in a new macOS project, Is it my mistake to use it?

let img = R.image.profile_default implies that img: [ImageResource]

but when i use callAsFunction, Xcode tips me an error let img = R.image.profile_default()

Cannot call value of non-function type 'ImageResource'

i'm using cocoapods

pod 'R.swift'

Is there something wrong?

[xiky]

Now i'm use like this NSImage(named: R.image.profile_default.name)

Please let me know if there is a better usage

That is correct.

There’s currently no better AppKit integration for images.

The only existing integrations are for SwiftUI and UIKit. See: https://github.com/mac-cain13/R.swift/blob/main/Sources/RswiftResources/Integrations/ImageResource%2BIntegrations.swift

As a workaround, you can copy-paste the UIKit callAsFunction extension in your own project, and adopt it for AppKit.

[tomlokhorst]

Note that if you are using Xcode 15, it also generates it’s own static resources. So there you can already do: NSImage(resource: .profile_default)

My apologies for being careless and not reading thoroughly.

Thank you very much for your response. I will close this issue.

#if os(macOS)
import AppKit
import RswiftResources.Swift

extension ImageResource {

    public var image: NSImage {
        get {
            let name = NSImage.Name(self.name)
            let image = (bundle == .main) ? NSImage(named: name) : bundle.image(forResource: name)
            guard let result = image else {
                fatalError("Unable to load image asset named \(name).")
            }
            return result
        }
    }

    public func callAsFunction() -> NSImage? {
        let name = NSImage.Name(self.name)
        let image = (bundle == .main) ? NSImage(named: name) : bundle.image(forResource: name)
        return image
    }
}
#endif

Here is an extension, perhaps useful, where I've also added an unwrapped image.
