When trying to build the most simple starter pack for PerfectlySoft Swift Server https://github.com/PerfectlySoft/Perfect, which simply involves the following steps per their website:
git clone https://github.com/PerfectlySoft/PerfectTemplate.git
cd PerfectTemplate
swift build
.build/debug/PerfectTemplate
I get the following error multiple times during the step "Linking COpenSSL" which causes the build to error out "error: exit(1)":
#escaping attribute only applies to function types
I'm building this with Xcode command line tools V:8.0 (8S201h). What do I need to be doing differently to get this to work?
Please, use DEVELOPMENT Snapshot instead a release version of Swift:

I am running Raspbian and have so far installed Swift 5.1.5 and cloned Vapor Branch 18.0.0 beta 27. I can't seem to get version 5.2 of Swift installed on my system somehow.
Nonetheless, the next step is to build Vapor, but it gives me the following error:
sudo swift build -c release
Updating https://github.com/jpsim/Yams.git
Updating https://github.com/apple/swift-nio.git
Updating https://github.com/vapor/console-kit.git
Updating https://github.com/apple/swift-log.git

fatal: Needed a single revision
Not sure where to go from there, can't find any relevant info online.
Vapor 4 and the new toolbox all require Swift 5.2 - you'll need to get the installed before anything else.
Next that's an old version of the toolbox, you can find the latest release at https://github.com/vapor/toolbox/releases
Finally, the chances are you don't need the toolbox. It's used for creating new projects. If you just want to build or run existing ones, just use the swift commands
I'm trying to create a kitura app, but got stuck at the first steps:
Created empty directory
swift package init --type executable
swift build
The result: Build output
I've tried reinstalling command line tools as well as xcode itself with no success..
Thanks in advance!
I want to add a FrameWork to this app I'm working on. It converts latitude and longitude coordinates to UTM coordinates.
I added this to the cartfile:
github "peterringset/UTMConversion" ~> 1.1
But when i run this code in the terminal to clone the framework:
carthage update --platform iOS
I get this error message:
A shell task (/usr/bin/env git clone --bare --quiet https://github.com/peterringset/UTMConversion.git /Users/Fallet/Library/Caches/org.carthage.CarthageKit/dependencies/UTMConversion) failed with exit code 128:
fatal: could not read Username for 'https://github.com': terminal prompts disabled
I've used other external frameworks like this, and it used to work just fine.. Any idea how I can fix this?
The problem occurs due to a change in username by the publisher of his GitHub account. If you notice the link to the repository is https://github.com/wtw-software/UTMConversion while the Carthage reference is "peterringset/UTMConversion". I was able to solve it by changing the Carthage reference to "wtw-software/UTMConversion". But then you will get this error if you are on Swift 3 or below and Xcode 8 or below.
Task failed with exit code 65.....This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details
So I digged into the logs and found this:
Check dependencies
“Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.
** BUILD FAILED **
I googled around this error and it looks like the project is developed with Swift 4 and with Xcode 9.
I am currently following the small and brief introduction to Swift Vapor by following their "Hello World" tutorial on their website. However I keep getting an error from swift-package when I try to build the project where it shows the following.
$ vapor build
No .build folder, fetch may take a while...
Fetching Dependencies [Failed]
Error: swift-package: error: unknown command: --enable-prefetching
I cannot seem to find out how to resolve this online. Anybody have any idea?
you have not mentioned your environment, so i'm giving solution for macOS.
I had the same issue, my swift version is 3.0.2 and vapor toolbox version is 1.0.9,
I tried the following thing to make it work
get into your project directory
create xcode project with command
swift package generate-xcodeproj
open xcode project
Select your scheme as App like this
and then build and run app
hope this helps!!
Make sure that you're using the correct command line tools for the Swift Version that you're using.
You can check from Xcode > Preferences > Locations > Command Line Tools
For me, using swift 3.0.2, vapor build command doesn't work neither.
However using swift 3.1.0, vapor build command works well.
My Vapor toolbox version is v1.1.0
I had the same problem, and I had Swift 3.1 installed. I deleted old version completely and installed new one and now it's building fine.
Try
rm -rf /usr/local/bin/vapor
brew tap vapor/homebrew-tap
than
brew install vapor
or
brew link vapor
if you have installed a new version previously.
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.
