I have a iOS app that tries to read an audio file using an AVAssetReader from a remote server. However the AVAssetReader never gets created, during creation it throws an error “Process aborted”. What is wrong with that code ?
BTW: The URL/resource is reachable and valid. I can play the file in the same app using SwiftUI’s VideoPlayPlayer !
if let url = URL(string: "https://my-server.com/audio.m4a") {
let asset = AVURLAsset(url: url, options: nil)
print(asset) // looks OK
do {
let assetReader = try AVAssetReader(asset: asset)
print(#fileID, #function, assetReader) // never reached
} catch {
print(#fileID, #function, error.localizedDescription) // instead I get error 'Vorgang gestoppt'
}
}
Any ideas ?

The AVAssetReader documentation says that
The assets you read may represent file-based media like QuickTime movies or MPEG-4 files, or media that you compose from multiple sources using AVComposition.
and AVComposition‘s header file documentation says
An AVComposition combines media data from multiple local file-based sources in a custom temporal arrangement
so it looks like AVAssetReader can only read file based, or compositions of file based assets and not remote assets.
