There isn't space here to show the entire code, so I'm trying to collect the bits that count from different parts of the app. The VC I am working with shows a progress bar for each scale on each horse. When I use a lengthy If statement, it works the way it should. However, it requires a lot of extra coding. I wonder if key paths could be a way of shortening my code (in reality there are 7 possibilities instead of three). I think I can make key paths work if I can figure out how to change var currentTraining and var currentBoost. Then I can make an IBAction to change the var and thus make the progress bar show the training progress. For now it only shows basicTraining, because that is what I have manually written in the var currentTraining. I need to do this programmatically with the scalesButton. I think I managed to include everything now, please let me know if there is anything else missing

//the following shows a progress bar with the stat selected with the scalesButton

//switch scaleIndex {
