Xcode
Apple's official development environment (IDE) for building iOS and macOS apps — where Swift/Objective-C code is written, tested, and packaged for release.

Like the fully-equipped workshop a contractor is required to build in — Apple's own toolset, not optional for iOS development the way some tool choices are.
Junior or senior?
Junior sounds like
Struggles with basic Xcode workflow — provisioning profiles, build settings.
Senior sounds like
Can describe an Xcode build or signing issue they debugged that wasn't actually about their app's code.
Ask them
“What's an Xcode build or signing issue you've had to debug that wasn't actually about your app's code?”
