Alerts are a standard UI element in iOS apps, used to inform users or request decisions. Though they seem simple, alerts involve many subtle guidelines around button order, roles, and colors. Mistakes here can confuse users. In this article, we’ll break down the correct use of alerts, highlight common pitfalls, and focus on Apple’s Human Interface Guidelines (HIG) to help you design clear and safe…

When creating a travel-planner app, it’s essential for users to provide information about their trips. One of the required fields is the visa type. To handle various visa types, we can utilize an enumeration called Visa:
During several interview processes, I’ve been asked many times about UIResponder and what the beast it is. I guess everybody can somehow explain this concept in iOS, which I did, but lack of in-depth knowledge frustrated me. So I decided to spend a few evenings to clarify it for myself.
