[Swift] Lightly introduce the logic of the app that passed the selection

In this article, I will introduce the UI and logic of the app that I made by selection. In the same way, people who will make apps by selection from now on, I hope it will be helpful for those who create apps as a portfolio. ✴︎ Please note that there are some parts that cannot be reached because it was made at explosive speed when it was immature.

the top screen

API used (national version of coronavirus infection status in Japan) https://covid19-japan-web-api.now.sh/api//v1/total I created an app that shows the status of coronavirus infection. Since the purpose is to know the infection status, the top screen shows the infection status of Decadeca and all over Japan.

The reload button on the upper left updates the infection status. The upper right is the chat button, which transitions to the chat screen, The buttons below also transition to the screen according to each name.

For the color scheme, I made a color list in advance and tried to make the color scheme uniform. While rotating the coronavirus icon by animation It is designed to move from outside the screen to inside the screen.

Chat screen

This is an idea implementation. It was created assuming that users who are uncertain whether they are infected can chat directly with a doctor. I'm using a library called MessageKit. Of course, it works with Firestore.

Health check screen

This is also an idea implementation. We pick up typical corona symptoms and distinguish points by severity. When you press the diagnosis completion button, the diagnosis result will be displayed as an alert according to the total points. The diagnosis result of the day is saved and displayed on the calendar.

Health Exam Screen-Diagnosis Result Alert

This is a diagnostic result alert. Since it is virtual, there is no basis. It's just an idea implementation.
