Recently, I developed an iOS app called Observe!!
Observe!! is a memory game app that enables people to improve their attention and memory skills by testing how well they can remember an image in a limited amount of time and respond to questions.
For the implementation of my app, I used XCode and Swift. I learned how to code Swift through a Udemy class. Since this was the first time I experimented with iOS mobile app development, there were many difficulties. One main difficulty was getting the constraints in Xcode right. Constraints position graphical elements on the screen to ensure the app looks good on all iOS devices (classic iPhone or plus size with the wider screen, tablet etc…) and on all screen resolution.
If you have an iOS device, please download Observe!! here!
