RxSwift supported operators

In some cases there are multiple aliases for the same operator, because on different platforms / implementations, the same operation is sometimes named differently. Sometimes this is because of historical reasons, while sometimes because of reserved language keywords.

When lacking a strong community consensus, RxSwift will usually include multiple aliases.

Operators are stateless by default.

Creating Observables

Transforming Observables

Filtering Observables

Combining Observables

Error Handling Operators

Observable Utility Operators

Conditional and Boolean Operators

Mathematical and Aggregate Operators

Connectable Observable Operators

Creating new operators is also pretty straightforward.
