What key factors do you check at the beginning of working on a new project?

When starting work on a new iOS project, I check the following key factors:

• Project requirements and goals: Clear understanding of functionality and objectives.
• Technical constraints: Minimum supported iOS version, libraries, and frameworks used.
• Application architecture: Choice of patterns (MVC, MVVM, VIPER, etc.).
• Integrations: APIs, third-party services, databases.
• Development environment: Xcode setup, CI/CD, testing.
• Design and UX: Availability of mockups, Apple guidelines.

For example, before starting development, I clarify which devices are supported and which functions should work offline.
