Load a Remote URL

[daihovey]

Has anyone attempted to build a version which could load a remote URL?
AVAssetReader complains currently "Cannot initialize an instance of AVAssetReader with an asset at non-local URL"

I've never actually tried that myself tbh. But you can simply download the file with URLSession. Code for this (just an illustration as it ignores all sorts of possible error scenarios) could look like this:

let task = URLSession.shared.downloadTask(with: remoteAudioURL) { downloadedURL, urlResponse, error in
    guard let downloadedURL = downloadedURL else { return }

    let cachesFolderURL = try? FileManager.default.url(for: .cachesDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
    let audioFileURL = cachesFolderURL!.appendingPathComponent("yourLocalAudioFile.m4a")
    try? FileManager.default.copyItem(at: downloadedURL, to: audioFileURL)

    DispatchQueue.main.async {
        self.WaveformView.waveformAudioURL = audioFileURL
    }
}
task.resume()
