When working with version control you usually have your project in a remote repository using a service like GitHub, GitLab, or Bitbucket.

When using Jujutsu you spend a lot of time working with changes.

In this article, you will learn how to create a Jujutsu repository, view the contents of a repository, and view the current repository status.

This article is the first in a series of articles introducing the Jujutsu version control system.

I recently created an Ash app, created the Ash domain and resources, and ran the mix ash.codegen to create a database migration.

You have a Hugo website.

I recently migrated several sites, including this one, from WordPress to Hugo.

I wanted to learn to use the Phoenix web development framework.

If you create a new project in Xcode 13, you will notice there is no Info.plist file on the left side of the project window.

When you create a new project in Xcode 13, you will notice there is no Products folder in the project navigator.

In Xcode 12 Apple consolidated many of their iOS app project templates into one template: App.

I see many people who ask a programming question on Reddit and do one of two things to show their code: They show a screenshot of their screen.

As part of Xcode 12, Apple added project templates for creating SwiftUI apps that run on both iOS devices and Macs.

If your Xcode project has multiple targets and you add a Swift package, Xcode will let you add the package to only one of the targets.

People constantly post on Apple’s developer forums complaining that when they try to install Xcode, an alert opens saying they don’t have enough disk space to install it.

Xcode 11 provides a subtle button to export a Mac app archive.

This post lists all the changes I found in Xcode 11 on version control.

When you create an iOS or Cocoa app project in Xcode 11, there is a User Interface menu in Step 2 of the New Project Assistant.

Xcode 11 makes it easier to open new editors.

Suppose you have an Xcode project with spaces in the name.

Xcode 10 has bug/limitation in creating Bitbucket repositories for your projects.

Xcode 10 lets you create a global .gitignore file so you don’t have to create a .gitignore file for each project you create.

I wanted to run a Ruby tool (packaged as a gem) in a Mac app, but I didn’t want people to have to install the Ruby gem to run my app.

Xcode 10 removes support for Subversion.

I have a two-part tutorial on making document-based iOS apps over at Swift Dev Journal.

In Xcode 10 you can tell Xcode to run your tests in random order.

In Xcode 10 you no longer need to hold down the Option key to clean the build folder.

If you create a document-based app project in Xcode, select the app target in the project editor, and click the Info button, you will see sections for imported and exported UTIs.

I want to let you know about a new site I launched, Swift Dev Journal.

In Xcode 10 projects use the new build system by default.

If your Xcode project is under version control, Xcode’s editor highlights the changes you make to the code.

Xcode 10 improves version control support for Bitbucket and GitLab.

In Xcode 10 the Library, where you access things like code snippets and user interface elements, is no longer in the lower right portion of the project window.

Dynamic Type on iOS lets people adjust the size of text to make text easier to read.

If you have done any programming in Xcode, you have come across the following error message when building your project: Linker command failed with exit code 1.

In this article you’ll learn about keyboard input accessory views and how to add them to your iOS app to make text editing smoother.

I was recently working on an iOS document-based app that saves the document in a file wrapper.

Back in 2010 I wrote an article on working with file wrappers.

I ran into an issue with a new document-based Cocoa app throwing exceptions when I tried to save the document.

One of the most read articles on this blog is An Introduction to Swift Unit Testing.

At WWDC 2018 Apple unveiled improved support for creating custom instruments for Instruments.

I tend to focus on Stack Overflow tags in the Apple ecosystem so there may be other tags that are misused.

Apple deprecated the Core Animation instrument in Xcode 9.3.

I released my latest book, Version Control for iOS and Mac Developers.

A common question I see on Apple developer forums is what version of Xcode can be used with a particular version of macOS.

I’ve recently seen multiple questions online from people having problems committing to git because the git repository had a detached head.

Something that can happen to you when using version control is you commit a change to the version control repository, realize you made a mistake, and want to go back to an earlier commit.

In a previous post, I showed how to tell git to ignore files in Xcode projects.
