Xcode provides project, build and debugging tools for Apple-platform development. Begin with a small app and understand the selected target and run destination.
Before you begin
Use a supported development setup and a small sample app. Record the toolchain, target and test device or simulator.
Work through the idea
Define a user task and the states the interface must represent. Test normal, empty and failed states as applicable, and consider larger text, narrow layouts and interrupted operations. Keep sample data fictional. Distinguish simulator checks from features that require validation on the intended physical device.
- Create an appropriate sample project
- Run on a simulator
- Inspect a simple variable at a breakpoint
Practice task
Build a greeting screen and change the displayed value through a small interaction.
Check your result
Record the project settings and explain where the app runs and where its state is stored.
A mistake to avoid
Do not assume simulator behavior proves every physical-device feature works.
Keep a review note
Save the inputs or scenario, your reasoning and the result you checked. Explain one assumption and one case that needs more work. Revise the exercise after feedback and distinguish what you demonstrated from what remains untested.
