Parce amplfy_outputs.json on IOS

[yegenpres]

Describe the bug

It to redefine auth password cfnUserPool.policies like in official documentation.

cfnUserPool.policies = {
  passwordPolicy: {
    minimumLength: 6,
    requireLowercase: false,
    requireNumbers: false,
    requireSymbols: false,
    requireUppercase: false,
  },
};

json looks like this:

   "password_policy": {
      "min_length": 6,
    },

amplify_outputs.json does not contain property name of passwordPolicy object if value is set to false.
Then Swift Coding fail to decode this object as result initAmplify just fails, because official library expects this fields like required.

public struct PasswordPolicy: Codable {
        public let minLength: UInt
        public let requireNumbers: Bool
        public let requireLowercase: Bool
        public let requireUppercase: Bool
        public let requireSymbols: Bool
    }

So we can every boolean value should be set to try or else it just miss in json file, and fail to parse it.

It means that output json should always generate fields with values set to false, or Codable struct accept optional parameters.

Steps To Reproduce

Steps to reproduce the behavior:
1. Go to backend.st
2. add this code: 
const { cfnUserPool } = backend.auth.resources.cfnResources

cfnUserPool.policies = {
  passwordPolicy: {
    minimumLength: 6,
    requireLowercase: true,
    requireNumbers: true,
    requireSymbols: true,
    requireUppercase: true,
    temporaryPasswordValidityDays: 20,
  },
};
3. Run app

Expected behavior

Amplify should init success.

Answering my own question. I think you are trying to mention this documentation.
It seems to be a bug in Gen2. Will transfer the issue

Hey @yegenpres 👋 thanks for raising this! I was able to confirm this behavior and have marked this as a bug

[josefaidt]

note: these properties should also be marked as required in the outputs schema for the password policy block https://github.com/aws-amplify/amplify-backend/blob/main/packages/client-config/src/client-config-schema/schema_v1.json#L59-L82
