Jenkins is an open source automation server. Jenkins provides hundreds of plugins to support building, deploying and automating any project. As an extensible automation server, Jenkins can be used as a simple CI server or turned into a continuous delivery hub for any project.

Xcode is an IDE used to develop, test, and distribute apps across all Apple platforms, featuring Swift and SwiftUI with a multiplatform app experience, enhanced editor features to help users code faster.
Jenkins is a highly customizable CI/CD tool with excellent community support. One can use Jenkins to build and deploy monolith services to microservices with ease. It can handle multiple "builds" per agent simultaneously, but the process can be resource hungry, and you need some impressive specs server for that. With Jenkins, you can automate almost any task. Also, as it is an open source, we can save a load of money by not spending on enterprise CI/CD tools.
This is almost not a case of Xcode being the 300-pound gorilla in the space, but of it being essentially the ONLY viable gorilla in the space. There are other text editors, of course, that can be used for coding; and in some cases other IDE's might make sense for a cross-platform development scenario, but since this is Apple's in-house tool, fighting against that flow is just going to be an exercise in frustration. And, if you need help from Developer Support, they are going to be most familiar with Xcode.
Automated Builds: Jenkins is configured to monitor the version control system for new pull requests. Once a pull request is created, Jenkins automatically triggers a build process. It checks out the code, compiles it, and performs any necessary build steps specified in the configuration.
Unit Testing: Jenkins runs the suite of unit tests defined for the project. These tests verify the functionality of individual components and catch any regressions or errors. If any unit tests fail, Jenkins marks the build as unsuccessful, and the developer is notified to fix the issues.
Code Analysis: Jenkins integrates with code analysis tools like SonarQube or Checkstyle. It analyzes the code for quality, adherence to coding standards, and potential bugs or vulnerabilities. The results are reported back to the developer and the product review team for further inspection.
We have a certain buy-in as we have made a lot of integrations and useful tools around jenkins, so it would cost us quite some time to change to another tool. Besides that, it is very versatile, and once you have things set up, it feels unnecessary to change tool. It is also a plus that it is open source.
Jenkins streamlines development and provides end to end automated integration and deployment. It even supports Docker and Kubernetes using which container instances can be managed effectively. It is easy to add documentation and apply role based access to files and services using Jenkins giving full control to the users. Any deviation can be easily tracked using the audit logs.
Xcode occasionally exhibits some behaviors that are hard to explain, but are generally cleared by restarting the program. In an application this large and complex, I suppose this is somewhat expected. The sheer vastness of the frameworks collection has to be a huge management issue all by itself. However, those breaks in the flow can have impact on developer productivity.
Since we don't use the cloud based features of Xcode, it is basically available 24/7 for us. We don't need the extended compilation features that are offered in the cloud as our projects to this point have not been that large or complex. We have never seen a wholesale breakdown of Xcode availability at any point in our use of the product.
No, when we integrated this with GitHub, it becomes more easy and smart to manage and control our workforce. Our distributed workforce is now streamlined to a single bucket. All of our codes and production outputs are now automatically synced with all the workers. There are many cases when our in-house team makes changes in the release, our remote workers make another release with other environment variables. So it is better to get all of the work in control.
Every developer wants faster compiles, but that can be achieved by either going to the cloud or by provisioning the local station to a higher powered configuration. My only minor complaint is the amount of local mass storage that Xcode as a system consumes. This makes it interesting to set up a development environment on a midrange laptop, however it is easily managed with external storage at a reasonable price.
As with all open source solutions, the support can be minimal and the information that you can find online can at times be misleading. Support may be one of the only real downsides to the overall software package. The user community can be helpful and is needed as the product is not the most user-friendly thing we have used.
It is worth well the time to setup Jenkins in a docker container. It is also well worth to take the time to move any "Jenkins configuration" into Jenkinsfiles and not take shortcuts.
Overall, Jenkins is the easiest platform for someone who has no experience to come in and use effectively. We can get a junior engineer into Jenkins, give them access, and point them in the right direction with minimal hand-holding. The competing products I have used (TravisCI/GitLab/Azure) provide other options but can obfuscate the process due to the lack of straightforward simplicity. In other areas (capability, power, customization), Jenkins keeps up with the competition and, in some areas, like customization, exceeds others.
Xcode is a much easier to use and full featured IDE than many of the competitors. It also is a way better experience to use. Much better looking in general
Xcode only loses points due to the occasional situation where it manages to somehow tie itself into a knot and starts to exhibit odd symptoms. This is almost always solved by simply saving progress and restarting the environment. Fortunately, that doesn't happen too frequently and is easily repaired while taking a short break to walk around and stretch.
