Hi,
I am writing to seek any help or workaround regarding an issue I have encountered while implementing Low-Latency HLS playback using the AVAssetResourceLoaderDelegate.
I have been successfully loading playlists during HLS live playback using the AVAssetResourceLoaderDelegate. However, after introducing Low-Latency HLS, I have run into a problem.
When the AVPlayer loads low-latency content playback natively, everything works fine. But when I use the delegate for loading, I encounter the following error from AVPlayer's status observer:
CoreMediaErrorDomain -15410
Low Latency: Server must support http2 ECN and SACK
It seems there is no problem since playback does not stop, but there is a very critical part missing. The playback does not achieve the expected low latency and behaves similarly to standard HLS.
Additionally, this behavior only occurs on iOS 16 devices and simulators. On iOS 17 simulators and devices, the error message does not appear, and the latency remains low as expected.
Therefore, I suspect that there might be some misjudgment in the verification process within the internal implementation of AVPlayer.
Since our app needs to support iOS 16, I would appreciate any solutions, methods to try, or workarounds that you could share regarding this issue.
Thank you.

Let's say I have a local package Foo, Bar and Baz.
Foo has Bar and Baz as dependency and has test target,FooTests.
Below is the Package.swift manifest that describes package Foo.
import PackageDescription
let packages: [Package.Dependency] = [
.package(path: "../Bar"),
.package(path: "../Baz"),
]
let products: [Target.Dependency] = [
.product(name: "Bar", package: "Bar"),
.product(name: "Baz", package: "Baz"),
]
let package = Package(
name: "Foo",
platforms: [
.iOS(.v16),
],
products: [
.library(
name: "Foo",
targets: ["Foo"]
),
],
dependencies: packages,
targets: [
.target(
name: "Foo",
dependencies: products,
path: "Sources"
),
.testTarget(
name: "FooTests",
dependencies: [.target(name: "Foo")],
path: "Tests",
swiftSettings: swiftSettings
),
]
)
Bar and Baz is also local packages.
Due to the limitations of the project, Baz has sources with symbolic links instead of exact directories, and these sources are what FooTests will test.
If I run FooTests, test succeed with proper logs indicating that all test methods are run correctly, but test coverage says that Baz's coverage is 0% and there is no executable lines unlike the Bar which is not what be tested.
Is there any way to fix this problem?
