Find the push environment of a device. (It doesn't actually reference `UIDevice` anywhere but this seemed like a good place to put it.)

UIDevice+Environment.swift

// From my answer https://stackoverflow.com/a/69905152/118631

import UIKit

public extension UIDevice {
    enum PushEnvironment: String {
        case unknown
        case development
        case production
    }

    var pushEnvironment: PushEnvironment {
        guard let provisioningProfile = try? provisioningProfile(),
              let entitlements = provisioningProfile["Entitlements"] as? [String: Any],
              let environment = entitlements["aps-environment"] as? String
        else {
            return .unknown
        }

        return PushEnvironment(rawValue: environment) ?? .unknown
    }

    // MARK: - Private

    private func provisioningProfile() throws -> [String: Any]? {
        guard let url = Bundle.main.url(forResource: "embedded", withExtension: "mobileprovision") else {
            return nil
        }

        let binaryString = try String(contentsOf: url, encoding: .isoLatin1)

        let scanner = Scanner(string: binaryString)
        guard scanner.scanUpToString("<plist") != nil, let plistString = scanner.scanUpToString("</plist>"),
              let data = (plistString + "</plist>").data(using: .isoLatin1)
        else {
            return nil
        }

        return try PropertyListSerialization.propertyList(from: data, options: [], format: nil) as? [String: Any]
    }
}
