<br>
<br>I have just started using the language and was trying to declare an enum inside a protocol.
<br>
<br>protocol WorkingEngine {
<br> enum States {
<br> Idle
<br> Pending
<br> Working
<br> Finished
<br> Canceled
<br> }
<br>
<br> var state: States { get }
<br>}
<br>
<br>The compiler refused this and I had to take the enum outside of the protocol:
<br>
<br>enum WorkingEngineStates {
<br> Idle
<br> Pending
<br> Working
<br> Finished
<br> Canceled
<br> }
<br>
<br>protocol WorkingEngine {
<br> var state: WorkingEngineStates { get }
<br>}
<br>
<br>This does not seem coherent with the rest of the language, as enums can be nested in classes, structs and even enums, but not to protocols.
<br>I haven’t found any proposal for this change. Is this the correct place to request it or get some opinion on the idea?
<br>
<br>Thanks a lot,
<br>
<br>Jakub
