Issue #577
objc[45250]: Class AVAssetDownloadTask is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/watchOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CFNetwork.framework/CFNetwork (0x4ddd0ec) and /Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/watchOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/AVFoundation.framework/AVFoundation (0x16aea494). One of the two will be used. Which one is undefined.

Then URLSession stops working.

The workaround is to remove Combine based API, and use completion block.
Instead of dataTaskPublisher
which hangs indefinitely, no sink
is reported
URLSession.shared
.dataTaskPublisher(for: url)
.map({ $0.data })
.decode(type: T.self, decoder: JSONDecoder())
.eraseToAnyPublisher()
.receive(on: RunLoop.main)
.sink(receiveCompletion: { completionStatus in
switch completionStatus {
case .finished:
break
case .failure(let error):
completion(.failure(error))
}
}, receiveValue: { value in
completion(.success(value))
})
just use normal
let task = URLSession.shared.dataTask(with: url, completionHandler: { data, response, error in
if let data = data, let model = try? JSONDecoder().decode(T.self, from: data) {
completion(.success(model))
} else {
completion(.failure(error ?? ServiceError.noInternet))
}
})
task.resume()
