Xcode 9’s Source Control preferences let you specify files to ignore so the version control system won’t track them.

Xcode 9: New Build System

September 21st, 2017

Filed under: Xcode | Be the first to comment!

Xcode 9 provides a preview of a new build system that has been built from scratch in Swift. The new build system is supposed to be faster and more reliable.

To use the new build system in one of your projects, you must enable the new build system for that project. Choose File > Project Settings to open the project settings sheet. Choose New Build System from the Build System menu under Shared Project Settings.

I didn’t notice much of a difference using the new build system, but I don’t have any huge projects that take forever to build with the old build system.

Xcode 8.3 removed the Use Storyboards checkbox for new Cocoa application projects. The checkbox has returned in Xcode 9 so you can choose whether to use storyboards or xib files for your project’s user interface.

Xcode 9: Swift Refactoring

September 18th, 2017

Filed under: Xcode | Be the first to comment!

Xcode 9 adds Swift refactoring support, something Swift developers have been asking for since Swift’s introduction. Choose Editor > Refactor to access the refactoring options. Xcode 9 has the following refactoring options:

  • Rename
  • Extract function
  • Extract method
  • Extract variable
  • Extract all occurrences
  • Add missing abstract class overrides
  • Add missing protocol requirements
  • Add missing switch cases
  • Convert to switch statement
  • Expand default
  • Generate missing function definitions
  • Wrap in NSLocalizedString

I haven’t had the chance to use the refactoring tools much so I can’t provide more detailed information on the Swift refactoring options. You can find more information on Swift refactoring in the following article on the Swift language website:

Xcode 9 makes it easier to work with GitHub. Start by adding your GitHub account to Xcode. Go to Xcode’s Accounts preferences, click the Add button, and choose GitHub to add your GitHub account.

Once you add your GitHub account to Xcode, you can go to any GitHub repository and clone the project in Xcode by clicking the Clone or download button and clicking the Open in Xcode link. You have to be logged into GitHub for the Open in Xcode link to be available.

You can learn more about Xcode 9’s improved GitHub support by watching the following WWDC video:
