@muskaan21 I'm sorry, but I think you missed that I'm working in a Swift Package, and not an application. Your instructions would probably work for an application, but not for a package.

Update: Still no success but I was able to prove that the font is indeed inside the module
I wrote a method to get available font URLs from the module like so:
static func fontNames() -> [URL] {
let bundle = Bundle.module
let filenames = ["CustomFont"]
return filenames.map { bundle.url(forResource: $0, withExtension: "ttf")! }
}
Calling this method at runtime and printing the result yields this:
font names: [file:///Users/davidokun/Library/Developer/CoreSimulator/Devices/AFE4ADA0-83A7-46AE-9116-7870B883DBD3/data/Containers/Bundle/Application/800AE766-FB60-4AFD-B57A-0E9F3EACCDB2/BestPackageTesting.app/BestPackage_BestPackage.bundle/CustomFont.ttf]
I then tried to register the font for use in the runtime with the following method:
extension UIFont {
static func register(from url: URL) {
guard let fontDataProvider = CGDataProvider(url: url as CFURL) else {
print("could not get reference to font data provider")
return
}
guard let font = CGFont(fontDataProvider) else {
print("could not get font from coregraphics")
return
}
var error: Unmanaged<CFError>?
guard CTFontManagerRegisterGraphicsFont(font, &error) else {
print("error registering font: \(error.debugDescription)")
return
}
}
}
When I call it like so:
fontNames().forEach { UIFont.register(from: $0) }
I get this error:
error registering font: Optional(Swift.Unmanaged<__C.CFErrorRef>(_value: Error Domain=com.apple.CoreText.CTFontManagerErrorDomain Code=105 "Could not register the CGFont '<CGFont (0x600000627a00): CustomFont>'" UserInfo={NSDescription=Could not register the CGFont '<CGFont (0x600000627a00): CustomFont>', CTFailedCGFont=<CGFont (0x600000627a00): CustomFont>}))
Any more ideas are welcome.
