Although I am not sayting that the IDE itself and the graphical whatever editing tricks are great. I focus more on the frameworks, libraries, supprt, tools and the integrated package that tranforms a mac to a development machine, and Apple has consistently been great at supporting the development on OS X macOS.
The suggestion might be to provide an integrated end-to-end pakcage that becomes the ultimate development environment so I won't have to install 3rd party packaging systems, library systems, extra-IDEs for different languages, and dozens of emulation, environment, and differnet packages and dependencies for differnet tasks.
Putting everything in Xocde seems a bad idea to increase the size and responsiveness of the software but it is much better than the overhead of doing fancy stuff and launching dozens of programs just to start working which takes up lots of concurrency resources which a dual-core laptop I am using might not be the best choice.
There are a few things I don't like about Xcode, but as a whole, it is the best totally free option for iOS development. Better yet, it is totally native. I am an amateur developer, and I have really enjoyed working on Xcode. I recommend giving it a try.

This often happens when you're trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate.
It can also happen if your certificate has expired or has been revoked. For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.

After following many outdated and incomplete instructions for setting up a web development environment on a Mac back in March , and spending a lot of time finding solutions to the problems I encountered along the way, I decided to put together this detailed tutorial.
In fact, the whole process can now be automated via the script that I wrote for you. For example, the installation instructions will differ depending on your shell Bash, zsh or fish , or if you are using a Mac with the Apple Silicon M1 chip versus an Intel chip. My script is smart enough to detect your current setup and install everything in the right place. If you prefer to do everything manually, keep reading. This tutorial is kept up to date and is guaranteed to work in , assuming you meet all the prerequisites below.
If you run into any issues, read this guide and see if you can figure it out on your own. Before you start, make sure you have the latest Apple software updates for your current macOS version.
Click on the Apple icon in the top left of your screen, then click on System Preferences, and then click on Software Update. If there are any updates available, install them.
The outdated tools message looks like this:. Homebrew usually provides detailed instructions for fixing things, so read carefully and follow their instructions. Quit and restart Terminal once the CLT are installed.
If you get errors other than the ones above, read through the Troubleshooting Homebrew section at the bottom of this guide. Back in , I used to use RVM, but once I automated this process, RVM kept breaking my script, so I switched to the much simpler chruby and have been using it happily every since. If it returns any info about rvm or rbenv, then you have it installed. If you do have it installed, uninstall it below. Follow the rbenv uninstallation instructions , then delete any lines related to rbenv from these files if they exist:.
The easiest way to open an application in macOS is to search for it via Spotlight. The default keyboard shortcut for invoking Spotlight is command-Space. Once Spotlight is up, start typing the first few letters of the app you are looking for, and once it appears, select it, and press return to launch it.
It should say arm64 if you are on an M1 Mac. Since you should no longer need this file. I always say yes to this.
Open the Applications folder and open the new version of Xcode. If you renamed Xcode, make sure you open the correct application. Xcode may prompt you to install additional components. Click install. This will take a few minutes. Once the components are installed, Xcode will launch.
If you encounter any errors while trying to build or run a project, check which device you are trying to launch. The new version may not remember the device you were using before. If so, click on the device and choose "Add additional simulators" from the drop down menu to add the device you want. If you don't need the older versions of Xcode on your computer, you can uninstall them and get some hard drive space back.
You can also delete the. Before making the switch to development, I was a strategist and GM in the tech space. If you read this far, tweet to the author to show them you care. Tweet a thanks. Learn to code for free. Get started. Forum Donate.
