Referencing a Struct not using the variable's name

Question

Hello I have a swift file that contains arrays of tuples that I reference with my app. For example, my structure looks like:

struct workoutDict {
   static var bicepWorkouts = [("Barbell Curl","Bicep",0,"3x10"), ("x","x",3,"x")]
}

I have a global variable named eqID. For example, eqID = "bicepWorkouts"

There is part of my code where I attempt to call this dictionary. Normally I would use: workoutDict.bicepWorkouts and this works fine, but I have other workouts such as barbellWorkouts in my dictionary so i let the user select "bicepWorkouts", "barbellWorkouts" ect based on user input and need to use that to reference my struct.

Right now i have

//Call the global variable to get what workout to look for
code = eqID
let ourWorkouts = workoutDict.code

which should set ourWorkouts = workoutDict.bicepWorkouts when our eqID is set to that, but it keeps giving me the error that workoutDict does not contain the code when I use that reference.

I tried researching alternate methods of referencing structs but I couldn't find anything. Any help would be appreciated!

You should create yet another dictionary to store the names:

struct workoutDict {

    static var dicts = [ "bicepWorkouts": bicepWorkouts, "barbellWorkouts": barbellWorkouts ]

}

Then you can access the sub dictionaries by:

workoutDict.dicts[eqlID]

Types, such as enums, classes, structs should have leading capitalised letter, i.e. struct Workout (and naming it WorkoutDict is not so good either, because 1) in Swift we do not abbreviate. and 2) That it contains a Dictionary is an implementation details. )

@Sajjon Thank you for those tips! i will remember that in the future.
