![]() It’s available on Homebrew/brew’s latest GitHub release. pkg installer also installs Homebrew to its default prefix ( /opt/homebrew for Apple Silicon and /usr/local for macOS Intel) for the same reasons as above. You have to confirm everything it will do before it starts. It tells you exactly what it will do before it does it too. It is a careful script it can be run even if you have stuff installed in the preferred prefix already. This prefix is required for most bottles (binary packages) to be used. The script installs Homebrew to its default, supported, best prefix ( /opt/homebrew for Apple Silicon, /usr/local for macOS Intel and /home/linuxbrew/.linuxbrew for Linux) so that you don’t need sudo after Homebrew’s initial installation when you brew install. Xcode installation is the time-consuming and huge job, we can simply avoid it if its possible to change Swift version using the toolchain.Instructions for a supported install of Homebrew are on the homepage. Using the Swift toolchain, we can avoid the hassle of installing different versions of Xcode for the sake of changing Swift version. Make sure all the dependencies are compatible with the Swift version that you have just switched to, otherwise app won’t compile.The build setting takes preferences over the installed Swift versions. SWIFT_VERSION build setting already set in the Xcode so make sure we have that toolchain installed. The latest version of Xcode might have some features that may not be compatible with old Swift versions.However, there are certain things to remember while changing the Swift version from latest Xcode. Now that, we have seen that how can we switch the Swift version without changing the version of Xcode. Note that above script is just an example, you can always customize as per your need of CI server. In order to see the new toolchain from the command line, we have to export the newly added toolchain. 3.1.1 snapshot, this will set the new Swift version for the local Xcode. ![]() Xcode -> Preferences -> Components -> Toolchains section and Select the It’s fairly easy to Switch to the new toolchain when we downloaded it successfully. ![]() It’s time to use the newly downloaded Swift toolchain. Now that, we have successfully downloaded Swift 3.1 development snapshot. Now you will see another tab for the “Toolchains” where we can pick the desired Swift toolchain for our local development without changing the Xcode version. Xcode -> Preferences -> Components section. ![]() app / Contents / Developer / Toolchains has user-specific toolchains. We can access the newly added toolchain from Xcode preferences as shown belowĪnother way, we can set the new toolchain in the Xcode preferences. $ / Library / Developer / Toolchains / swift - 3.1 - DEVELOPMENT - SNAPSHOT - 2017 - 06 - 14 - a. e.g for beta versions we can switch to beta Xcode using However, if we have multiple Xcode versions installed we can switch the Xcode developer directory using xcode-select utility. Xcode developer directory for the located at We can always find the version of Swift with Xcode in the release notes. The new release of Xcode always has a latest stable version of Swift e.g Xcode 9.3 shipped with Swift 4.1. Xcode and Swiftīefore jumping into changing Swift versions, let’s talk about how the Xcode and Swift version are related to each other. In this post, we will see how we can switch between multiple Swift version without changing Xcode versions. Apple ship new Xcode version with the newest version of Swift all the all the time, it often requires iOS developers to switch the Xcode versions or keep multiple version of Xcode at the same time. Swift is evolving day by day but we have to make sure our apps or libraries still work with constantly changing Swift. However, since Apple has open-sourced Swift, it is going through major breaking changes. There is no doubt that Swift is amazing programming language to develop iOS apps. ![]()
