I was following the instructions here, but was not able to get vapor working on my mac. Here're my xcode and swift versions
Xcode 8.0
Build version 8S174q
Apple Swift version 3.0-dev (LLVM 8fcf602916, Clang cf0a734990, Swift 000d413a62)
Target: x86_64-apple-macosx10.9
When I try to install the toolbox using this command
curl -sL toolbox.qutheory.io | bash
The installation is unsuccessful and yields this message
⚠️ It looks like your Command Line Tools version is incorrect.
Make sure Xcode > Preferences > Locations > Command Line Tools is set correctly.
Correct: Xcode 8.0 (8S162m)
Current: Xcode 8.0
Build version 8S174q
⚠️ It looks like your Swift install location has been modified.
Correct: /usr/bin/swift
Current: /Users/<name>/.swiftenv/shims/swift
❌ Incompatible
Reason: Invalid Swift version
Output must contain 'swiftlang-800.0.33.1'
Current 'swift -version' output:

From this, I can gather that my swift location is wrong (I don't remember changing it) and that my xcode build number is wrong (because xcode beta 2 is no longer available for download, so I got xcode beta 3.)
Can anybody help me to get this working without changing too much, or is this framework still too finicky to work with a slightly different setup?
Unfortunately it's impossible to create packages that work between different Swift 3 development previews because of how much changes in each preview. Things that compiled today might not compile tomorrow and there is no way to selectively target a given preview in code.
Because of this, the Swift version declared in https://github.com/qutheory/vapor#-current-environment for a given Vapor version must be the one used.
Vapor 0.14 relied on the Swift 3.0 preview 2 version that comes with Xcode 8 beta 2. There is currently no way to download Xcode 8 beta 2 now that Apple has stopped hosting it upon the release of Xcode 8 beta 3. That was an oversight.
Vapor 0.15 will not rely on Xcode 8 beta previews and should be released in a few days.
Open Xcode and make sure the correct SDK is selected:
👀 Xcode > Preferences > Locations > Command Line Tools
Select XCode 8
Then continue with the tutorial you are following.

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.
After I updated my App to Swift 4 I get this error message:
error: The following binaries use incompatible versions of Swift:
/Users/Konrad/Library/Developer/Xcode/DerivedData/ExploreYourCity-btthjezgywzvnmduiurzwgwzrven/Build/Products/Debug-iphoneos/Cosmos/Cosmos.framework/Cosmos
/Users/Konrad/Library/Developer/Xcode/DerivedData/ExploreYourCity-btthjezgywzvnmduiurzwgwzrven/Build/Products/Debug-iphonesimulator/ExploreYourCity.app/ExploreYourCity
I can not find a solution to this misstake. Whats wrong?
Library setup method: CocoaPods
Version of the library. Example: 12.0.1.
Xcode version. Example:9.0.1.
OS version. Example: iOS 11.0.
*Swift Version: Swift 4.0.
1) Select Project in Project Navigator.
2) Go to General Tab.
3) Remove everything under Embedded Binaries.
4) Remove everything under Linked Frameworks and Libraries except Pods_*.framework
5) Clean, Build and Run.
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/
Does anybody know how to get Realm, via Carthage, for Xcode Beta (9M136h)? If I try grabbing the most recent version (2.8.1) I get a compiler error, stating that the framework was built using Swift 3.1 and thus cannot be used in Swift 4 projects. However the release notes for 2.8.1 states that it's compatible for Xcode 9 Beta. Does the binary for 2.8.1 not work for X9B? Do I have to use a --no-binary flag (gross)?
Thanks in advance!
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}"
