Crash on APILanguage.default

[Dulatheo]

Hi, team! We have noticed in crashlytics that our users sometimes have a crash on APILanguage.default line. Basically, the crash happens for iOS 12 users. We are using 2.0.14 version. Here is some screenshots and code where crash happens:

    private func getLanguage() -> APLanguage {
        var language = APLanguage.default //37th line
        switch Locale.selectedLanguage {
            case .ru:
                language = .ru
            case .en:
                language = .en
            case .kk:
                language = .kz
        }
        
        return language
    }
