When an alternative toolchain is chosen you will notice an icon in the activity view in the Workspace toolbar. There is no way to remove the default toolchain. You can also choose which toolchain you want to use as well as validate its signature or remove it. You can also see installed alternative toolchains under Toolchains pane of Components preferences in Xcode as you can see in the image below. Right after installing a new toolchain you will notice a new submenu under the Xcode menu where you can easily change the currently enabled toolchain. a user library ( ~/Library/Developer/ Toolchains) - makes it available only to that user.the top-level library ( /Library/Developer/Toolchains) - makes it available for all users who share accounts on that computer.We can choose to install alternative toolchains into one of the two locations: Just download the chosen toolchain package and simply follow the installer steps. For the moment of writing this article, it would be 5.2 snapshots. The better option would be more stable snapshots that come from branch for a specified swift version. So if you haven't given up on it yet and can't wait for the new diagnostics why not give it a try right now? Installing alternative Toolchainįrom the official Swift website we can download snapshots from the master branch which are rather not recommended for our daily development as they have not gone through the full testing that is performed for official releases. But it might be still worth installing.Įveryone that has tried SwiftUI has probably noticed how hard it is sometimes to find an issue with our code as the error messages are misleading most of the time. Just keep in mind that to submit your application to the App Store you must build it using the version of Swift that comes included within Xcode - using default toolchain that is. All we have to do is install the alternative toolchain that is available to download from website. Xcode comes by default with the latest stable toolchain release of the Swift, thankfully it supports using alternative toolchains instead of default one out of the box. version 11.3 of Xcode is now like 16 GB? That's quite a lot and having like 2 or even 3 versions of Xcode installed might not be possible for some of us, especially if one uses his MacBook not just for single project development but also for some other stuff as well. How can we give a new Swift version that has not been released with the latest available Xcode yet? Or maybe you are short on free disk space (sooner or later we all know that feeling I think □) and do not want to install a new version of Xcode yet? Toolchains take way less space (around 2-3 GB) compared to Xcode. Usually, we can compile them anyway with backward compatibility by setting older Swift versions for that framework but sometimes the new version of Swift brings a great addition that it is just too good not to use that. Especially if your application depends on some third party frameworks since those will rather sooner than later be updated to support the new Swift version. Even though we, developers, are not forced to use the newest Swift version right away when it is released it might be still good to be ready for it. Most important, however, we want to prepare our applications for a new Swift version. New releases do not only contain some minor fixes and improvements but we also often get some new features as well. Swift development isn't slowing down in any way new versions are being released a few times a year. So, once known the latest acceptable version to update Xcode in OS X for El Capitan - I am assuming that in is possible to download in peace the specific. Therefore, is there an official table indicating or showing all versions of Xcode that can be installed for each OS X and macOS release? How to know what is the latest acceptable version of Xcode for a specific OS X or macOS? With the suggested search criteria appears as result many Xcode versions Now, the reason for this post, I want to have the latest acceptable version of Xcode for El Capitan for it to work fine with MacPortsĪccording with this comment at Xcode is not currently available from the Software Update server, it does mention to use the Command Line Tools as search criteria at the URL (btw that URL redirects to ). The command works and returns: version: 8.14 To know the Xcode version the following command should be used: pkgutil -pkg-info=_Executables According to its page it needs Xcode.Īccording to this post: Determine xcode command line tools version
