SSL_ERROR_SSL(1): operation failed within the libr

I am getting some SSL Errors (which are causing my project to stop/hang with no crash as I have a DispatchGroup waiting for the request), which I don't know how they are caused, what they are, or what to do about it.

I have read numerous pages roughly about this problem, but there are not much documentation or people having the same problem. I have tried changing the info.plist but that doesn't seem to have helped. Both plist's look like this: (accounts.spotify.com is the domain for the URL of the access token request)

enter image description here

I can see that my code is failing when I make a request to the server. (This is in my framework). As mentioned earlier, I have a DispatchGroup waiting for this request but the code stops.

self.currentToken = try self.spotifyRequest("https://accounts.spotify.com/api/token", method: .post, parameters: parameters)

My request method:

private func spotifyRequest(_ url: URLConvertible, method: HTTPMethod, parameters: Parameters? = nil, headers: HTTPHeaders? = nil) throws -> JSONStandard {
    // Create a dispatch group to handle threads
    let group = DispatchGroup()
    group.enter()

    // Status of the request (starts as nil)
    var status: JSONStandard?


    DispatchQueue.global(qos: .userInitiated).async {
        Alamofire.request(url, method: method, parameters: parameters, headers: headers).responseJSON(completionHandler: { response in
            // Check if response is valid
            if let requestResponse = response.result.value as? JSONStandard {
                status = requestResponse
            } else {
                status = nil
            }

            // Let the next tasks be completed, it has finished waiting for the request
            group.leave()
        })
    }


    // Wait for a result
    group.wait()

    // Return value or throw an error
    if let safeStatus = status {
        return safeStatus
    } else {
        getAccessToken()
        throw SpotifyError.failedToCompleteRequest
    }
}

I'm not exactly sure what caused the problem, because all I did was slightly edit and archive the framework again.

However, earlier it worked on both (as I am using this universal framework script)

Here is my crash log (which I can't understand any of!):

This is all for a Spotify request through Alamofire which previously worked and now mysteriously doesn't. It does not work on my device OR the simulator.

Is this a problem relating to secure internet connections? Or is this another problem?

Some links to what I have looked at:

Edits:

Is this a problem on Spotify's servers? Or a bug in Xcode 10? I moved my framework .swift files to my project, and still get the logs.

I also get these errors before my request, strange

I had the same warning with codegen Swagger in emulator on any response call. But all worked. This warning disappeared only when I added environment variable Hide strange unwanted Xcode logs

Deadlock

I assume spotifyRequest will be called on the main thread.

So if the main thread reaches the line

group.wait()

and this line of responseJSON completionHandler was not called yet:

group.leave()

then the main thread is blocked due to the call of group.wait() above. Due to the blocked main thread group.leave() can't be called. Classical deadlock.

Verfication

Setting a breakpoint to the line

if let safeStatus = status {

shows that this line is never called.

Minimal Example that is running

As a starting point here the code for a minimal example that delivers a result.

import UIKit
import Alamofire

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.contactSpotify {
            print ("result: \(String(describing: $0)) error: \(String(describing: $1))")
        }
    }

    func contactSpotify(completion: @escaping ([String: Any]?, Error?) -> Void) {
        let url = URL(string: "https://accounts.spotify.com/api/token")!
        Alamofire.request(url,
                          method: .post,
                          parameters: ["grant_type": "refresh_token",
                                       "client_id": "<someClientId>",
                                       "refresh_token": "<someRefreshToken>",
                                       "client_secret": "<someClientSecret>"])
            .validate()
            .responseJSON { response in
                guard response.result.isSuccess else {
                    completion(nil, response.result.error)
                    return
                }

                completion(response.result.value as? [String: Any], nil)
        }
    }

}

This gives as output in the console:

result: Optional(["access_token": XXX, "scope": user-read-email user-read-private, "token_type": Bearer, "expires_in": 3600]) error: nil

see Screenshot: console output

ATS Settings in info.plist

Spotify offers a valid TLS certificate chain on their server. So there is no need for ATS settings in info.plist.

SSL Warnings in Console

I get the same SSL warnings in the console when I run the application on an iOS 12 simulator like you. Nonetheless the connection is established and the request delivers data. Perhaps this is gone in one of the next betas.
