Support of primitive types for List

[mitevdev]

Goals

class Entry : Object {
   ...
   dynamic var tags = List<String>()
}

and then:

let results = realm.objects(Entry.class).filter("any tags == %@", "foo")   // or
let results = realm.objects(Entry.class).filter("any tags contains[c] %@", "foo") // or
let results = realm.objects(Entry.class).filter("any SELF.tags in %@", ["foo"])

Expected Results

Results populated with Entry objects having "foo" in tags field

Actual Results

'Invalid value', reason: 'Expected object of type (null) in IN clause for property 'tags' on object of type 'Entry', but received: foo'

Steps to Reproduce

just create a realm and put one instance of Entry class then try to fetch it by searching by tags

On one side:

Lists can be filtered and sorted with the same predicates as Results.

and

The aggregate expressions @count, @min, @max, @sum and @AvG are supported on List and Results properties

but on the other side:

Note that querying Lists containing primitive values is currently not supported.

This is actually not an issue, primitive types in queries for List are not supported yet.

[bdash]

Support for queries involving arrays of primitives is being tracked at #5334.
