A build from the master branch of swift-format fails when executed against the Swift 5.3 toolchain that came with Xcode 12 Beta 2.
Based on the docs and the error message on execution the issue is almost definitely related to the SwiftSyntax versions not matching between swift-format and the Swift 5.3 toolchain. I've tried updating the swift-format Package.swift file to build swift-format against the SwiftSyntax release/5.3 branch but still get this error:
The loaded '_InternalSwiftSyntaxParser' library is from a toolchain that is not compatible with this version of SwiftSyntax
The question is what needs to be changed in swift-format Package.swift to make execution against the Swift 5.3 toolchain work?
The answer may be as "simple" as knowing which SwiftSyntax commit is packaged with the Swift 5.3 toolchain that came with Xcode 12 Beta 2. The answer may also be that I'm being way too bleeding edge for my own good.
Tony Allevato - I think you are the boss on this.
I was able to build Xcode 12 compatible version like this:
This revision of swift-format compatible with Swift 5.3(download it to your computer)
In Package.swift SwiftSyntax has to be pinned to Swift 5.3 tag
.package(url: "https://github.com/apple/swift-syntax", .revision("swift-5.3-RELEASE")),
swift build -c release
The binary will be in .build/release folder. Though there are some deprecation warnings, it works just fine.

I'm building a Swift static library with:
Xcode 13.2 (Swift compiler 5.5.2)
iOS Deployment target 12.0
Build library for distribution YES
Skip install NO
Swift language version 5 and tried with 4.2
Dependency managed with CocoaPods:
Japx 3.0.0
Alamofire 5.2.2
RxSwift
When I try to add it to an iOS project with this setup:
Xcode 13.3 (Swift compiler 5.6)
iOS Deployment target 12.0
Swift language version 5 and tried with 4.2
and build I get this error:
Failed to build module 'LibraryX'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.5.2 effective-4.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)', while this compiler is 'Apple Swift version 5.6 effective-4.2 (swiftlang-5.6.0.323.62 clang-1316.0.20.8)'). Please select a toolchain which matches the SDK.
These are the headers in the .swiftinterface
// swift-interface-format-version: 1.0
// swift-compiler-version: Apple Swift version 5.5.2 effective-4.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)
// swift-module-flags: -target arm64-apple-ios12.0 -enable-objc-interop -enable-library-evolution -swift-version 4.2 -enforce-exclusivity=checked -Onone -module-name LibraryX
Obviously if I build the project with the same compiler version or building the library with the iOS project everything works fine. But the purpose here is to release a precompiled library and not its source code.
Every time that I lookup this error online I've found "You have to set Build library for distribution to Yes"
I tried to add the source code of the static library to a new Framework project, but I get the same result.
I also had this error, in my case it was unable to import a sub-dependency of my XCFramework during reading .swiftinterface file, however was showing this absolutely misleading error.
After repeatedly cleaning up DerivedData and trying different Xcode versions (13.0, 13.4.1) I've seen 2 errors: "this SDK is not supported by the compiler", and "No module named 'AnotherLib'" which was an incorrectly specified dependency inside of my Swift Package.
So, maybe only first part of the message is correct "Failed to build module 'LibraryX'", but the reason is something else, NOT the difference in compiler versions.
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.
I am trying to update the swift compiler language version to 5.1. But I am having the latest xcode version of Version 11.3.1 (11C504) Toolchain: Swift 5.1 Snapshot 2020-01-28 (a).
I downloaded the swift-5.1-DEVELOPMENT-SNAPSHOT-2020-01-28-a-osx package and installed but the is added in the toolchain. I couldn't see the required version in the compiler section.
So how to update that.
I have added the screen shot for more details
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 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

When I try to install the toolbox using this command
curl -sL toolbox.qutheory.io | bash
The installation is unsuccessful and yields this message

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.
