<br class="gmail_msg">
<br class="gmail_msg">I have just started using the language and was trying to declare an enum inside a protocol.
<br class="gmail_msg">
<br class="gmail_msg">protocol WorkingEngine {
<br class="gmail_msg"> enum States {
<br class="gmail_msg"> Idle
<br class="gmail_msg"> Pending
<br class="gmail_msg"> Working
<br class="gmail_msg"> Finished
<br class="gmail_msg"> Canceled
<br class="gmail_msg"> }
<br class="gmail_msg">
<br class="gmail_msg"> var state: States { get }
<br class="gmail_msg">}
<br class="gmail_msg">
<br class="gmail_msg">The compiler refused this and I had to take the enum outside of the protocol:
<br class="gmail_msg">
<br class="gmail_msg">enum WorkingEngineStates {
<br class="gmail_msg"> Idle
<br class="gmail_msg"> Pending
<br class="gmail_msg"> Working
<br class="gmail_msg"> Finished
<br class="gmail_msg"> Canceled
<br class="gmail_msg"> }
<br class="gmail_msg">
<br class="gmail_msg">protocol WorkingEngine {
<br class="gmail_msg"> var state: WorkingEngineStates { get }
<br class="gmail_msg">}
<br class="gmail_msg">
<br class="gmail_msg">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 class="gmail_msg">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 class="gmail_msg">
<br class="gmail_msg">Thanks a lot,
