Accessing WPF Resources on Cocoa and Island/Darwin

On Cocoa, and Island/Darwin, App resources inside a bundle are accessed at runtime by using a Cocoa API such as NSBundle.pathForResource:ofType: (typically on the application's main bundle instance) to obtain the filename on disk. After that, regular file APIs can be used to load the file in.

var lFileName := NSBundle.mainBundle.pathForResource('MyText') ofType('txt');
var lText = File.ReadText(lFileName);

var fileName = NSBundle.mainBundle.pathForResource("MyText") ofType("txt");
var text = File.ReadText(fileName);

var fileName = NSBundle.mainBundle.pathForResource("MyText", ofType: "txt")
var text = File.ReadText(fileName);

var fileName = NSBundle.mainBundle.pathForResource("MyText") ofType("txt");
var text = File.ReadText(fileName);

Some additional APIs are provided for special resource types. For example image and icon files can also be loaded using the static NSImage.imageNamed or UIImage.imageNamed, on macOS or iOS, respectively.

Please refer to the Cocoa, AppKit and UIKit documentation from Apple for details.
