So, I spent more time in the foundation course than on the challenge recently.

I managed to get the API working and can display the latest results in a nice ScrollView.
For the pictures, I downloaded them all, converted them to PNG and added them to the asset list. I named them just as the homeTeamID / awayTeamID, which is basically just a number. Converting to a string and there it is, the image :wink:

Next tasks:

  • Get the “last” and “upcoming” views to work.
  • Display the standings
  • Let the user choose his/her favorite team and make it visible in the scores and standing tabs.

So, there is a lot to do, I hope I can find enough time next weekend.

Very slow progress currently.
Figured out, how to sort the standings. Not very complicated, “just” needed to find the correct syntax.
Next part is: How to sort and eliminate data points. So, the teams are either in “league” NL or AL. They all have a “leagueRank” ( like 1, 2, 3, 4 and so on). That means, two teams will have the same “leagueRank”. I think I need to create a new array, only with teams in the NL league and then sort them by leagueRank. Same goes for the AL league. For me, that sounds easy, but as a beginner, I struggle WHERE I create the new array and where I can sort it, before I display it in a ForEach loop. Oh well, another 8 days to go, only one weekend left. Will figure that out.

Code snippet for sorting by wins and then, if wins are equal, by losses:

do {
let standingsTestData = try decoder.decode([StandingJSONTest].self, from: data)

            let sortedStandingsOverall = standingsTestData.sorted {
             // sort by wins; if wins are equal, sort by losses
                ($0.wins, $1.losses) > ($1.wins, $0.losses)
            // Return the Standings
            return sortedStandingsOverall

So, I came to a solution how to filter for the American League and National League for the standings. It’s working, which is good. Though I don’t think that I got the most efficient solution.

In the beginning, I wanted to use a tuple to get the data for the MLB (overall), National League (NL) and American League (AL). I got to the point that I could do the filtering and assigning the values to the arrays, but I got stuck to initialize the data.
So I created three classes, one for MLB, one for AL and one for NL. This data is then displayed in the standingsView. Again, as the code is very similar, I bet there is a solution with less repeating code, but for now I decided to have the code for the MLB, AL and NL and with if statements (which picker is selected), the standings are displayed.

Here is a code snipped for the AL in which I removed all “NL” teams and then sorted by the league rank (which is given by the API/JSON data).

do {
                let standingsTestData = try decoder.decode([StandingJSONTest].self, from: data)
                let sortedStandingsLeagueALfiltered = standingsTestData.filter { !$0.league.hasPrefix("NL") }
                 let    sortedStandingsLeagueAL = sortedStandingsLeagueALfiltered.sorted {
                    $0.leagueRank < $1.leagueRank
                // Return the Standings
                return (sortedStandingsLeagueAL) 

To have a more consistent look, I added a small “headline” to the overall standing and I put in a similar for the AL and NL (just scroll down to see the NL):

So, the 6 division leagues are also shown. This time 2x filtering (for AL/NL and then for East/Central/West) and sorting for the division rank.

Created some subviews to be able to show all the Z/V/HStacks :wink:

Quite happy with the latest progress.

Open tasks:
Views for last and upcoming games
Indicate user’s favorite team

Afterwards, I might try to clean up the code


It’s done!

The last open tasks are completed, the app is ready :slight_smile:
Have a look into my solution:

Thank you :slight_smile:
That was a fantasic challenge, I learned a lot, and I think the result is quite nice :slight_smile:

Hey @Wildsparrow how did you get the logos? I have been trying to use the WikipediaLogoUrl from the API but the SVG format is giving me hell

When I read that some people struggle with the SVG images, I decided to download them from the wikipediateamlogo-url, covert them to PNG, named them as the teamID (for example 1.png), and put them in the assets folder of the app.
As awayTeamID, homeTeamID and teamID is the same, it’s really easy to display them in the scores and standings views.
Strangely, one logo was already linked as png in the wiki-links. Maybe that gives you the trouble?

Thanks a lot man, I just went and download them as well.

Another app challenge, another entry in my journal :wink:

This time, I will start with a concept “app”, just showing the progress bar/circle and how to transfer data to Apple HealthKit.
In the next step, I will do the basic layout of my app and describe the functionality. Probably by then, I will post the progress here.
Then, I will merge the gained knowledge of my concept app with the “real” app.

Let’s get this started :mechanical_arm:


So, building the progress circle (or progress rectangle or any other shape) is quite easy.
I want to give my remarks to the linked article/tutorial:

There is no need to write self in front of the progressValue or the progress. This was required in an earlier version of Swift, but not anymore. Without self, I think it’s more intuitiv.
To let the progress start at the top of the circle, you could use .rotationEffect(Angle(degrees: 270)) but instead of 270 you could also specify -90 (again, I think this is more intuitiv).
I added a “Reset” button to play around without stopping and starting the “app”.


import SwiftUI

struct ContentView: View {
    @State var progressValue: Float = 0.0
    var body: some View {
        ZStack {
            // Just another background color
            VStack  {
                // Progress circle
                ProgressBarView(progress: $progressValue)
                .frame(width: 200, height: 200, alignment: .center)
                // Button to increment the value
                Button(action: {
                }, label: {
                    HStack {
                        Image(systemName: "plus.rectangle.fill")
                            .font(.system(size: 25))
                    .overlay(RoundedRectangle(cornerRadius: 20)
                                .stroke(lineWidth: 2.0)
                // Button to reset the value
                Button(action: {
                    progressValue = 0.0
                }, label: {
                    HStack {
                        Image(systemName: "scribble.variable")
                            .font(.system(size: 25))
                    .overlay(RoundedRectangle(cornerRadius: 20)
                                .stroke(lineWidth: 2.0)

    func incrementProgress() {
        let randomValue = Float([0.0500, 0.125, 0.225, 0.343].randomElement()!)
        progressValue += randomValue

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {


import SwiftUI

struct ProgressBarView: View {
    @Binding var progress: Float
    var body: some View {
            //Background circle
                .stroke(/*@START_MENU_TOKEN@*/Color.blue/*@END_MENU_TOKEN@*/, lineWidth: 20)
            //Progress circle
                .trim(from: 0.0, to: CGFloat(min(progress, 1.0))) // no need to put self.progress anymore, just progress
                .stroke(style: StrokeStyle(lineWidth: 20, lineCap: .round, lineJoin: .round))
                // Start the progress circle at top (circle goes clockwise and if the start of the circle needs to be ajusted, it's also clockwise, so 3x90° = 270° but -90 would also be OK
                .rotationEffect(Angle(degrees: 270)) // order is important: .rotationEffect as firt point right after Circle() will result in an error

            // Text inside the circle
            Text(String(format: "%.0f %%", min(progress, 1.0)*100)) // modifier will round the value, so there is no decimal point

Formatting is strange. If anyone wants to use the code, just delete the START MENU TOKEN and END MENU TOKEN

Result should look like:

So, getting / asking for access to the HealthKit for the water consumption is working. Also for reading the data (which is 0 in the simulator; I hope it’s really 0 and not a bug :wink: ).

Tomorrow, I will try to write the water consumption amount to the healthKit data and display it.

Then, I will try to add more functionality (like consumption of water, coffee, tea, soda, beer, wine … something like that) and finally will create a new app which incorporates all the learnings from this app challenge.

Stay tuned :slight_smile:


Playing around with the settings page …


Just a quick update:

On the pro side:

  • I strengthen the skills I learned in the foundation course
  • I struggled with some “simple” tasks but could solve them
  • I force myself to create “reusable” code instead of writing the same code or even similar code two times (or even more) in a project. Easy example: I defined a color for my button. I wrote this code directly to the button in the view. Then I needed the same color somewhere else and I wrote the same code again (copy&paste) in that place. Then I wanted to make a slight change to the color. Argh. So I defined the color as a variable and used that variable all over the place.
  • I also try to structure my code to make it more readable. As an example, I put all the code in the action part of the button. There are some if else clauses, so the whole action part got quite long. I then created functions and just referred to those functions in the action part of the button. Looks way more professional.

On the negative side:

  • I’m far behind my schedule :smiley:

Some key learnings:

  • Do not name your view “TabView” if you want to use a tabView in this view … it will not work and you will only see an error message with no suggestions how to solve it. I renamed my into TabViewHydration.
  • If you think you’re smart by displaying a numerical keyboard to make sure that the user can only input an integer value … you will find out, that the numerical keyboard will not disappear like the default keyboard when you tap anywhere on your screen. You need to add a button which does UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)

The last part made me think to get the user weight by the HealthKit. I will put this on my nice-to-have-list.


Still not finished. Why?
I was on vacation and there was some increased workload at my regular job before/after that
I still struggle to decide/use the correct variable types to pass data between the views. Looking at tutorials clear things up, but take some time
I still struggle to decide where (in which file) all the calculations should be done in the most efficient way
Although I think that this monthly challenge is great to learn the fundamentals … the app topic itself is kinda boring to me. I was more enthusiastic to display sports data than counting how much water you drink each day. Yeah. Stupid excuse. I know.

So, I have a nice splash screen to ask for access to the HealthKit

And the screen to enter your drinks:

The face on the glass is changing based on the overall progress.
I can control the pickers individually.
I have the calculations done to add the drinks (and limit the overall intake to max 20% juice/soda and 20% of alcoholic beverages)

A picture of the settings tab is shown in above posting.

Still I need to do some work on the buttons and their actions and reset the values every day at midnight.

My plan is to finish the app within next week.

Add all the logics to not be able to get to a minus value for the water intake: :white_check_mark:

Still to do:
Write values to the HealthKit
Store data in user defaults
Create video of the working app
Reset all values each day

Ohhhhhhhh :slight_smile: First time writing data to HealthKit and it’s working! :mechanical_arm:
As a beginner, it is a great feeling to extend the existing methods to calculate the amount of milliliters of the water intake (and for my 20% cap of soda and beer), link to the new variable and save the amount to HealthKit.
Probably as a total beginner, I would have written additional methods, but now I could just add some more lines to existing ones.

Aaaaaand, I can not only add the water intake, but also subtract if the user decides to do so. That was someting I feared I would not be able to do so easily.

Need to get some sleep now, will continue tomorrow.

(For me, there are so many small details in my app, I don’t know how to show everything in a short video :smiley: )

The more I work on that challenge, the more I love it!

It´s done :slight_smile:
