So if you navigate here, you'll find instructions saying that the package manager is bundled in the downloads on this page.
It says that I can check with:
swift build --help
But my only output has been:
:0: error: no such file or directory: 'build'
I have downloaded both installation packages and installed them. I can see that the toolchains are installed here. (I also installed the previous version out of desperation).
The instructions aren't very explicit and in a world of all in one IDE's, I haven't yet experienced installing a language of my own in this way. Is there something obvious I'm missing in the process?
Do you have the PATH environment variable setup to map to the correct Swift?
swift --version should show
Apple Swift version 2.2-dev (LLVM 46be9ff861, Clang 4deb154edc, Swift 778f82939c)
Target: x86_64-apple-macosx10.9
If you are running a Swift version prior to 2.2, then you need to set your path to the new toolchain installed by the Swift 2.2 snapshot. This can be done by editing your .bash_profile and adding
export PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:$PATH
as the last line and then source ~/.bash_profile to update your settings.
Edit
On December 10, 2015 there was a new snapshot released. --version still shows 2.2-dev but shows updated (SHA-1?) hashes.
Apple Swift version 2.2-dev (LLVM 7bae82deaa, Clang 53d04af5ce, Swift 5995ef2acd)
Target: x86_64-apple-macosx10.9
These releases are also tagged at the individual project level as a release: https://github.com/apple/swift/releases

I'm using xCode 13.1 with macOS 12.0.1 Monterey. I added KingFisher and removed it from my pod. but my project is not built anymore. I got this error for one of my local SDKs:
Failed to build module 'CbSdk';
this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.4
(swiftlang-1205.0.26.9 clang-1205.0.19.55)', while this compiler is 'Apple Swift version 5.5.1
(swiftlang-1300.0.31.4 clang-1300.0.29.6)'). Please select a toolchain which matches the SDK.
What I've done but didn't work:
pod deintegrate and pod install.
restart xCode with clearing cache and DerivedData.
checkout old branch and commit that worked before.
moving code to another macBook that worked before.
download, install and select toolchain 5.4 (odd errors appeared -> )
changing swift compiler language of my target and project to swift 4 (It says you are using swift 5.5.1 again!)
note that I didn't update xcode or swift!
Taken from this Twitter thread.
You need to set the BUILD_LIBRARY_FOR_DISTRIBUTION build setting on the framework target

I fetch the same problem when I try to update a library. My Xcode version was 13.2 with the swift version5.5.2. But the library I want to update required a swift version of 5.7.0. Using toolchains in Xcode might be the solution but I decided to update the Xcode version with the latest.
I update my Xcode to the latest version 14.1 and the issue is resolved. Automatically the swift version is found on the latest Xcode.
Some time after upgrading to Xcode 9, I discovered that I was no longer able to build a Kitura-based project with the Swift 3.1.1 snapshot (which I have installed via swiftenv).
When I ran swift build, some time into the build I would get:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.apinotes:8:28: error: unknown key 'SwiftImportAsNonGeneric'
SwiftImportAsNonGeneric: true
^
<unknown>:0: error: could not build Objective-C module 'Foundation'
It seems that there is a dependency between Swift and Xcode, and Xcode 9 is no longer fully compatible with Swift 3.1.1 (or earlier) snapshots. I believe it may be because my project uses Foundation, and Foundation on Mac is provided as part of Xcode, whereas on Linux it is part of the Swift snapshot (via swift-corelibs-foundation).
I did find a solution to this problem: If I keep a copy of Xcode 8.3.3 around (eg. in /Applications/Xcode8.3.3.app) then I can use sudo xcode-select -s /Applications/Xcode<version>.app/Contents/Developer to select the appropriate one prior to building with SPM, and I can then build both Swift 3.1.1 and 4.0 projects on the same system.
However, this feels a bit clunky. Each time I build a project with the 'other' Swift version, I have to make sure I run xcode-select, or the build will fail. Is having multiple versions of Xcode the right solution in this case, or am I missing a trick with Xcode 9?
note that if, like me, you upgraded Xcode via the App Store, previous versions of Xcode are still available from https://developer.apple.com/download/more/
I upgraded Xcode to 8.1 GM and am now getting the below error for SwiftyJSON. Other imported frameworks seem to work. Is there a way to force this to work in Swift 3 until SwiftyJSON upgrades their framework? I used Carthage to import/update frameworks. I also tried changing Use Legacy Swift language version On and Off to no avail.
Module compiled with Swift 3.0 cannot be imported in Swift 3.0.1:
Modules/SwiftyJSON.swiftmodule/arm64.swiftmodule
SwiftyJson is being downloaded precompiled by carthage. The precompiled download is with Swift Version 3.0. That makes the compiler complain that the version is not correct. Using the following command:
carthage update --platform iOS --no-use-binaries
SwiftyJson (and all other frameworks within Carthage) will be compiled locally using the local version of Swift (3.0.1) and the compiler will not complain anymore.
Remove the app chache from DerivedData, and rebuild. the error may be fixed.
The DerivedData path like this:
~/Library/Developer/Xcode/DerivedData/
Make sure you've placed the new XCode 8.1 GM package in your Applications folder. We ran into this issue when one of us was running Carthage to update our dependencies, but had not replaced the XCode old 8.0 application in the applications folder (8.1 GM was running off the Desktop).
You want to make sure that when you run the following in terminal: xcrun swift -version that it returns Apple Swift version 3.0.1.
Updating default Xcode to new one on terminal worked for me.
Step 1 : Use following command to update Xcode version to latest on Terminal. Ref
sudo xcode-select -switch <path/to/>Xcode.app
Step 2 : Now try carthage update command
carthage update --platform iOS
Just to give the latest updates:
Carthage has released version 0.20 on Feb 27, 2017.
Carthage now only uses the pre-build binary if available pre-build binary is compatible.
That is being said, you no longer have to use: --no-use-binaries to avoid incompatible pre-build framework.
So make sure that you have carthage version greater than 0.20 and simply do:
carthage update --platform iOS
Just like #zirinisp said:
You can Using the following command:carthage update --platform iOS --no-use-binaries
Using the following command:xcrun swift -version to see the Swift version
Do this: Xcode->preferences->locations to clear the derived data and archives data, the most important to change the command line tools to "Xcode 8.1"
Using the following command:xcrun swift -version,you can see the swift version is 3.0.1
Set Use Legacy Swift Language Version = NO
I hope it will help you
Move the beta/GM version if the Xcode to /Applications folder and name it Xcode-beta
Check the output of:
xcrun swift --version
by running this command in terminal, its output should match with the swift version you want the app to compile, because Carthage uses output of this command, to determine the local Swift version.
Update Xcode version to latest on Terminal by running following command:
sudo xcode-select -s /Applications/Xcode-beta.app/
Build the libraries for iOS and prevents Carthage from downloading existing (yet incompatible) precompiled binaries, by running following command:
carthage update --platform iOS --no-use-binaries
Clean & Build
I had exactly the same issue with the library XCTest_Gherkin, what it worked for me was:
Product -> Scheme -> XCTest-Gherkin
Product -> Build
Hope it helps. I am using Cocoapods.
In Xcode Build Settings make sure your Framework Search Paths contain the appropriate Carthage Build folder:
$(inherited)
$(PROJECT_DIR)/Carthage/Build/iOS
I'm trying to run Kitura project on XCode. I tried to follow instructions on this page ([https://github.com/IBM-Swift/Kitura/wiki/Building-your-Kitura-application-on-XCode]), however I failed with step 3 – run swift build -X. I get this error:
error: unable to invoke subcommand: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-build (No such file or directory)
Looks like I have latest toolchain installed (see the screenshot below).
I also have both XCode 7.3.1 and XCode 8 beta. What would you suggest to solve that problem?
As Daniel mentioned above, Kitura right now requires use of the June 6 drop of the Swift Development toolchain. This toolchain can only be used with Xcode v7.3.1. The toolchain format changed between Xcode 7.x and newer Xcode 8 beta. When using the Xcode 8 beta with the new June 20 toolchain, there's another step that you need to do before you can run swift build from the command line.
From the command line, enter the following command:
$ sudo xcode-select -s /Applications/Xcode-beta.app/Contents/Developer/
This command is necessary to inform Xcode where to find the required binaries and frameworks.
To switch it back, just use the same command but point it at non-beta version of Xcode:
$ sudo xcode-select -s /Applications/Xcode.app/Contents/Developer/
Using these commands will eliminate the error <unknown>:0: error: Swift does not support the SDK 'MacOSX10.11.sdk' error: exit(1): that you ran into.
The Xcode 8 beta will be required to be used for all future Swift.org toolchains unless otherwise specified.
As of this writing, Kitura only compiles with the 06-06 Swift Development toolchain so make sure you have that installed.
In addition the wiki was out of date, the generate Xcode project command got renamed to swift package generate-xcodeproj. I updated the wiki to reflect this change.
Try:
export PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:"${PATH}"
I am currently following the document from swift.org to play around with the new Swift Package Manager.
I cloned the demo project from Github and run the following command from terminal.
git clone https://github.com/apple/example-package-dealer.git
cd example-package-dealer
swift build
.build/debug/Dealer
While I run swift build, error arise.
<unknown>:0: error: no such file or directory: 'build'
Any idea?
I stuck for an hour. Sadly, it's just an epic fail that downloading the wrong swift package. If you want to use swift build, MAKE SURE you download the development version.
You did not add the newly installed swift to your PATH. The instructions for doing that are here.
On OS X:
export PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:"${PATH}"
On Linux:
export PATH=/path/to/Swift/usr/bin:"${PATH}"
Then to test it works:
swift build --version
I think it is a problem with the latest snapshot:
Ubuntu 14.04 Swift 2.2 Snapshot of January 11 contains swift-build in usr/bin
Ubuntu 14.04 Swift 2.2 Snapshot of January 25 doesn't contain swift-build in usr/bin
Besides, the January 25 release also seems to miss other files (libFoundation.so and libXCTest.so in usr/lib/swift/linux for instances).
Either there has been a structure change....or, simply, the latest snapshot had a problem ;)
While they fix the snapshot, simply take the older (January 11th) snapshot, and you should be fine.
I was facing the same issue and in my case, I recently updated my Xcode to 8.2.1 and swift 3.0 comes with it.
I was getting this log.
Ranvijay-Mac-mini:PerfectTemplate ranaranvijaysingh$ swift build
error: unable to invoke subcommand: /Library/Developer/CommandLineTools/usr/bin/swift-build (No such file or directory)
The path it was taking was incorrect. It was suppose to be:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
To change the path, run this command.
export PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin:$PATH
And DONE.
Run : swift build again on your project and if you get this error.
xcrun: error: unable to lookup item 'PlatformPath' from command line tools installation
xcrun: error: unable to lookup item 'PlatformPath' in SDK '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk'
error: Invalid platform path
then you need to change the SDK path as well.
In my case, I had two .sdk at path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
MacOSX.sdk MacOSX10.12.sdk
To know what is your SDK path, run this command.
xcrun --sdk macosx --show-sdk-path
My case i got this.
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
To change it run this command.
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
and NOW DONE.
Try running swift build now.
