Hello,
We are modularizing our iOS project using SPM. One of those modules is our UI module, which contains a bunch of Resources, for example, custom fonts.
In order to register the fonts, we use the following code to access the resources:
swift
Bundle.module.urls(forResourcesWithExtension: "otf", subdirectory: nil)
This is the recommended way from Apple as seen here - https://developer.apple.com/videos/play/wwdc2020/10169/.
This seems to be working when importing the module into our main app.
The problem appears when this code is executed from a Playground within the same module. When the code is executed, a fatal error is thrown:
unable to find bundle named UniverseUI_UniverseUI
This is triggered from the generated file resource_bundle_accessor.swift which contains the following code:
swift
import class Foundation.Bundle
private class BundleFinder {}
extension Foundation.Bundle {
/// Returns the resource bundle associated with the current Swift module.
static var module: Bundle = {
let bundleName = "UniverseUI_UniverseUI"
let candidates = [
// Bundle should be present here when the package is linked into an App.
Bundle.main.resourceURL,
// Bundle should be present here when the package is linked into a framework.
Bundle(for: BundleFinder.self).resourceURL,
// For command-line tools.
Bundle.main.bundleURL,
]
for candidate in candidates {
let bundlePath = candidate?.appendingPathComponent(bundleName + ".bundle")
if let bundle = bundlePath.flatMap(Bundle.init(url:)) {
return bundle
}
}
fatalError("unable to find bundle named UniverseUI_UniverseUI")
}()
}
Lastly, our module target defines resources like so:
swift
resources: [.process("Resources")]),
Is there any workaround so we don't trigger the fatalError when executing that code from a playground? Any check to know if Bundle.module is available?
Thank you
