Swift 5.7 errors on build

[pnewell]

I successfully built the 5.7 branch using Xcode 14.0.1 but am having trouble building the example weather app. I am getting the following errors:

> Task :app:swiftBuildX86_64Debug FAILED
Swift PM flags: --configuration debug -Xswiftc -DDEBUG
error: dataCorrupted(Swift.DecodingError.Context(codingPath: [], debugDescription: "The given data was not valid JSON.", underlyingError: Optional(Error Domain=NSCocoaErrorDomain Code=3840 "Unexpected end of file" UserInfo={NSDebugDescription=Unexpected end of file})))
SWIFTPM_PD_LIBS was deprecated in favor of SWIFTPM_CUSTOM_LIBS_DIR

I also noticed if I try to build the "core" package directly with the toolchain it gives me this error:

error: ExitCode(rawValue: 1)
[0/1] Planning builderror: 'basic_package': Invalid manifest
/Users/paulnewell/Development/basic_package/Package.swift:4:8: error: no such module 'PackageDescription'
import PackageDescription

Also noticing that when I try to build in Android Studio, it is creating the following folder in "build-tools": "1.9.7-swift5.4"

I'd expect this to be something else given I am using the 5.7 branch, but not sure if that is expected or not

I am testing out the new prebuilt 5.7 release, thanks for your work on this! Unfortunately it looks like there isn't an Xcode version that used 5.7.3, which means on Mac we dont have an option we can use?

Hi,

You can use XCode 14.2. Changes between 5.7.2..5.7.3 were so minor that Apple decided not to rebuild the new version swiftlang/swift@swift-5.7.2-RELEASE...swift-5.7.3-RELEASE
Also, you can install the toolchain from Swift.org and switch the toolchain to custom with `export TOOLCHAIN=swift'
