Using password hash by Laravel for Swift 5

Website store user/pass in Firebase, and pass is hash by Illuminate\Encryption\Encrypter. My IOS app is connect to Firebase, and need to authentication by use/pass what is stored in database (not by Firebase authentication) same as website. I want to know how i can encrypt pass from app to compare with pass in Firebase? I know my case is not common case, and not good program, but i must make it. This is code decrypt by Laravel

Crypt::decryptString($value['acc_password']))
