Why does non-optional types have optional: true?

[abaig-experlabs]

subtype {
type = string;
indexed = NO;
isPrimary = NO;
array = NO;
set = NO;
dictionary = NO;
optional = YES;
}
type {
type = string;
indexed = NO;
isPrimary = NO;
array = NO;
set = NO;
dictionary = NO;
optional = YES;
}
swx_stag {
type = string;
indexed = NO;
isPrimary = NO;
array = NO;
set = NO;
dictionary = NO;
optional = YES;
}

@arturdev can you help me in this?

[arturdev]

What is this? And what help do you need?

i made an update to ask for requiredProperties just like indexedProperties.
It's intended for realm sync.

I still don't understand what is the problem and what you want to achieve.
Can you please elaborate?

Currently, there is no way to specify required properties. Why I need this is because of realm sync. Realm sync is used to sync ream data on MongoDB cloud which is realm's database. So in order to make it compatible with realm sync, i added some updates in the code and sent it to you.
