Field

public struct Field: Expression, Selectable, BridgeWrapper, SelectableWrapper,
  @unchecked Sendable

A Field is an Expression that represents a field in a Firestore document.

It is a central component for building queries and transformations in Firestore pipelines. A Field can be used to:

• Reference a document field by its name or FieldPath.
• Create complex BooleanExpressions for filtering in a where clause.
• Perform mathematical operations on numeric fields.
• Manipulate string and array fields.

Example of creating a Field and using it in a where clause:

// Reference the "price" field in a document
let priceField = Field("price")

// Create a query to find products where the price is greater than 100
firestore.pipeline()
  .collection("products")
  .where(priceField.greaterThan(100))
