Let say you have an enum:

typedef enum {
    Sunday,
    Monday,
    Tuesday,
    Wednesday,
    Thursday,
    Friday,
    Saturday
} DayOfWeek;

when writing a switch statement, a Xcode is trying to help with switch statement snippet:

and then:

great, but I need to list all enums:

DayOfWeek day = ...; // a day of week
switch (day) {
    case Sunday:
        break;
    case Monday:
        break;
    case Tuesday:
        break;
    case Wednesday:
        break;
    case Thursday:
        break;
    case Friday:
        break;
    case Saturday:
        break;
    default:
        break;
}

Unfortunately, have to do it manually :( Is there any known snippet to populate all cases? Of course I saw some answers 3 years old states that it is impossible, but maybe something changed since that time? Any ideas?

Saw your question and decided to build an Xcode plugin that does exactly that.

Enums and switch Statements in swift, Because Xcode does not autocomplete a switch with enum cases. Installation. Clone or download the repo; Open SwitchCaseGenerator. How to autocomplete enum switch using Xcode? (4) Short Answer : Use Editor > Refactor > Add Missing Siwtch Cases. Convenient way : Open Preferences by pressing [command] + [,] in Xcode. Go to Key Bindings tab and set a shortcut for the command Refactor > Add Missing Switch Cases.

Short Answer :

Use Editor > Refactor > Add Missing Switch Cases

Convenient way :
  1. Open Preferences by pressing [command] + [,] in Xcode.
  2. Go to Key Bindings tab and set a shortcut for the command Refactor > Add Missing Switch Cases.
  3. Input the shortcut in editor. Be sure the cursor is on switch letters.

timaktimak/SwitchCaseGenerator: An Xcode Source Editor , Enums are also great for developers as it lowers our chances of errors or typos due to providing us autocomplete. Instead of having the values set inside the switch statement , we can actually store them in the enum with� The Visual Studio is a powerful IDE (Integrated Development Environment). It provides some convenient features for speed up the coding. For example, if you want to write a switch statement to test each possible cases for a enum variable. First step, is to type in switch and press TAB key, this will produce this.

in Xcode 10 do the following

  1. add switch...case template and set your enum type instead of self so that xcode understands what it should autocomplete

  1. move cursor inside word switch and go to menu > editor > refactor > expand switch cases

This is what you will get as result

Enumerations in Swift for Newbies. | by Farhan Syed, I've started a Playgrounds in XCode 9.2 and for some reason autocomplete doesn't work properly, words in the file that have 's' in them and 'switch', wich actually completes a switch stub. Try typing library function or enum and enjoy! Not a fun issue to deal with when trying to create a WWDC scholarship playground. An Xcode Source Editor Extension that makes a swift switch case statement with selected enum cases. Why? Because Xcode does not autocomplete a switch with enum cases. Installation. Clone or download the repo; Open SwitchCaseGenerator.xcodeproj; Enable target signing for both the Application and the Source Code Extension using your own developer

Unfortunately this is not possible with Xcode out of the box. File a bug report and select the request an enhancement option.

I actually did this myself lately, and they gauge the severity and importance of bugs/enhancements by the number of duplicates they receive for a given issue - hence one of the reasons for not being able to search the tracker.

Swift Playgrounds Autocomplete, Change which Xcode is used with xcode-select from the command line. As an extension, C++11 enums with fixed underlying types are now supported in all language Interface Builder's device bar lets you switch between the light and dark Semantic highlighting, code completion, live issues, symbol search, and� switch (switch_on) {default:} and the word “switch_on” will be selected. Change that switch_on to your enum variable’s name, in this case g, and then press the down-arrow cursor key (other keystrokes might work, but I know that down-arrow definitely does) and VS will automagically fill in the switch statement with the values: switch (g)

While Xcode won't autocomplete the entire switch statement, there are tricks to speeding up writing them. This is what I've been doing lately:

  1. Start the switch autocomplete, and type the expression
  2. Copy the case block and paste it enough times to cover all the enum constants (actually, I just paste more than I need and delete later, rather than counting)
  3. Move the cursor to before the first constant placeholder
  4. Press TAB, then the first letter of the constant, then Enter to accept the first autocomplete suggestion
  5. Repeat TAB, letter, ENTER for the rest. Autocomplete won't suggest constants you've already used in the switch, so the list narrows with each use.

Of course, it really helps if all the constants start with the same letter. In your case, consider naming them:

typedef enum {
    dayOfWeekSunday,
    dayOfWeekMonday,
    dayOfWeekTuesday,
    dayOfWeekWednesday,
    dayOfWeekThursday,
    dayOfWeekFriday,
    dayOfWeekSaturday
} enumDayOfWeek;

Xcode 11 Release Notes, Swift lets you auto-complete the value name from the list of cases defined. Using switch statement with Swift enum. var today = DaysOfAWeek.Monday today = . enum days { sunday, monday, tuesday, wednesday, thursday, friday, saturday } You can also define an enumeration with custom values to the constants declared. But you need to have an instance variable, a constructor and getter method to return values.

Swift enum, enum Device { case iPad case iPhone var year: Int { switch self { case .iPhone: In order to understand protocol with enums, We'll create a Game. In which, a� The keyword “enum” is used to declare an enumeration. Here is the syntax of enum in C language, enum enum_name{const1, const2, .. }; The enum keyword is also used to define the variables of enum type. There are two ways to define the variables of enum type as follows.

Advanced Enum (Enumerations) by Example, To create an enumerations, use enum keyword and place their entire definition within a pair of 1.3 Matching Enumeration Values with a Switch Statement. In this enum tutorial, I want to just focus on using an enum in a switch statement. Hopefully this enum/switch example adds a little more complexity to my earlier examples. A Java enum switch statement example. In this enum/switch example, I first declare an enum type that looks like this: enum Day { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY

Enum (Enumerations) by Example, Raw strings, future enum cases, compactMapValues(), and more! Try it yourself : I created an Xcode Playground showing what's new in Swift 5.0 with examples you can edit. That completion handler will itself accept a Result , where the " https://www.hackingwithswift.com") { result in switch result { case� In C#, an enum (or enumeration type) is used to assign constant names to a group of numeric integer values. It makes constant values more readable, for example, WeekDays.Monday is more readable then number 0 when referring to the day in a week. An enum is defined using the enum keyword, directly inside a namespace, class, or structure. All the

  • Consider using AppCode from JetBrains jetbrains.com/objc/features : Intention Actions - Multiple intention actions are there to improve your code, or make some routine work easier. They allow you to create symbols from usage, declare methods, swap parts of a boolean expression, merge nested 'if's, **generate switch cases**, and so on.
  • You can't do it with Xcode out of the box. File a bug report and request the enhancement. bugreport.apple.com
  • @Jeff you should promote your comment to an answer.
  • Thanks @diogot, done.
  • I've installed SCXcodeSwitchExpander, but it doesn't work in my case. What I did: Installed Alcatraz. installed switch expander, relaunch XCode multiple times. What did I do wrong?
  • This works pretty well. I could not find any possibility to create a key shortcut for this. All other refactor options are configurable but not this one. Could you find a possibility?
  • Hey @PhilippOtto! I'm searching for a way to add a shortcut for that as well, have you found anything useful?
  • @MuhamedAlGhzawi no unfortunately not
  • Work very well with Xcode 11.3.1, but we have to put a cursor at a switch word.
  • What's the radar #? Makes it easier to duplicate.
  • The Bug Reporter isn't searchable is it? Nonetheless, this the ID of the ticket mine was marked as duplicate against - 9663422
  • No, but I'll just file a bug report with body "Duplicate of 9663422". Makes it easier for all of us.
