Development Tools

Xcode

Xcode is Apple's IDE for building apps on iOS, macOS, watchOS, tvOS, and visionOS. It includes everything: code editor, visual design tools, debugging, simulators, and distribution tools.

How I Use It

Xcode is essential for my app development workflow:

• SwiftUI Previews — See live UI changes without running the app
• Simulator — Test on virtual iPhones, iPads, and Macs
• Debugging — Breakpoints, variable inspection, step-through
• Instruments — Profile performance and find memory leaks
• App Store Connect — Archive and upload builds for release

Essential Shortcuts

• ⌘R — Run the app
• ⌘B — Build without running
• ⌘. — Stop running app
• ⌘⇧K — Clean build folder
• ⌘⇧O — Open Quickly (find any file)
• ⌃⌘J — Jump to definition
• ⌘/ — Toggle comment
• ⌘⌥P — Resume SwiftUI preview

Xcode + Cursor Workflow

I use both tools together. Cursor for writing and editing code with AI assistance, Xcode for running, debugging, and profiling. Both can have the same project open—changes sync via the file system.

Common Fixes

When Xcode acts up: Clean Build Folder (⌘⇧K), quit Xcode, delete the DerivedData folder, restart. This fixes 90% of mysterious issues.
