This works for me:

object SharedPreferenceHelper {
    private val PREF_FILE = "SharedPreference"

    enum class StringValues(val defValue: String) {
        Test1("");

        fun set(context: Context, value: String) {
            context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).edit().putString(name, value).apply()
        }

        fun get(context: Context): String? = context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).getString(name, defValue)
    }

    enum class IntValues(val defValue: Int) {
        Test1(0);

        fun set(context: Context, value: Int) {
            context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).edit().putInt(name, value).apply()
        }

        fun get(context: Context): Int = context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).getInt(name, defValue)
    }

    enum class LongValues(val defValue: Long) {
        Test1(0);

        fun set(context: Context, value: Long) {
            context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).edit().putLong(name, value).apply()
        }

        fun get(context: Context): Long = context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).getLong(name, defValue)
    }

    enum class FloatValues(val defValue: Float) {
        Test1(0f);

        fun set(context: Context, value: Float) {
            context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).edit().putFloat(name, value).apply()
        }

        fun get(context: Context): Float = context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).getFloat(name, defValue)
    }

    enum class BooleanValues(val defValue: Boolean) {
        Test1(true);

        fun set(context: Context, value: Boolean) {
            context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).edit().putBoolean(name, value).apply()
        }

        fun get(context: Context): Boolean = context.getSharedPreferences(PREF_FILE, Context.MODE_PRIVATE).getBoolean(name, defValue)
    }
}
