I have an array weekOneExerciseArray that has 4 strings inside of it. I have a label that I want to assign each of these strings to, each on a new line. At the moment I've just written the individual array elements before attempting to write a more optimised version. However I get
Cannot subscript a value of type '[String]' with an index of type
on the exerciseString = "\(exerciseString)\n (weekOneExerciseArray[exerciseCount])"; } line.
I've tried so many variants to get this working but to no luck. I would be very thankful for any help!
let weekOneExerciseArray = ["Reverse Crunch", "Crunch", "Oblique Crunch", "Rope Crunch"];
//Week 1: 4 exercises
exerciseTextLabel.text = "\(weekOneExerciseArray[0])\n\(weekOneExerciseArray[1])\n\(weekOneExerciseArray[2])\n\(weekOneExerciseArray[3])";
var exerciseString = "";
for exerciseCount in weekOneExerciseArray
{
exerciseString = "\(exerciseString)\n\(weekOneExerciseArray[exerciseCount])";
}
exerciseTextLabel.text = exerciseString;
The reason for getting the error is in the for-in you are trying to access an element of an array by using a string as an index:
for exerciseCount in weekOneExerciseArray
{
exerciseString = "\(exerciseString)\n\(weekOneExerciseArray[exerciseCount])";
}
At this point, exerciseCount is a string but not an integer, so what you should do instead is:
for i in 0..<weekOneExerciseArray.count {
exerciseString = "\(exerciseString)\n\(weekOneExerciseArray[i])"
}
and you would be good to go.
However, I would highly recommend to follow the following approach instead:
You could group up weekOneExerciseArray by joining its elements using joined method for generating the desired concatenation:
let weekOneExerciseArray = ["Reverse Crunch", "Crunch", "Oblique Crunch", "Rope Crunch"]
let concatenatedString = weekOneExerciseArray.joined(separator: "\n")
print(concatenatedString)
/*
Reverse Crunch
Crunch
Oblique Crunch
Rope Crunch
*/
exerciseTextLabel.text = concatenatedString
