Running Swift build in Terminal leading to "Platform Path" errors - swift

I recently reformatted my Mac. Today I tried building a swift executable via Terminal to start a server-side swift project. Here are the commands I've used:
swift package init --type executable
swift build
Upon running swift build, I got the following errors:
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'
I'm running Xcode 8.3.1.
Thanks in advance!

Try fixing the SDK path (yours appears incorrect):
$ xcrun --show-sdk-path --sdk macosx
You might have this result:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
Switch the default SDK location by invoking:
$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
If that doesn't work then take a look inside the (normal) SDK path:
$ ls -lat /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
You should see the SDK's within that directory; if not you'll need to download them.

Select a version of Xcode which can run the swift build command by running, for instance:
sudo xcode-select -switch /Applications/Xcode-8.3.3.app
Where Xcode-8.3.3 is the name of your Xcode application

How to enable code completion on Coderunner tool for swift language

Any help with swift language code completion on coderunner, would be much appreciated.
On the website https://coderunnerapp.com/ its claimed that it does support it, but not sure if I need to enable it explicitly or if I'm missing something.
Setup Active Directory
In Terminal run
xcrun swift --version
If you see the version information, you’re all set. If the command fails with xcrun: error: unable to find utility "swift", not a developer tool or in PATH, you need to set the active developer directory:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
Create a Swift Template in CodeRunner
Open Preferences and switch to the Languages tab. Create a new entry in the list and name it “Swift”.
In the “Run Command:” text field, enter this command:
xcrun swift -sdk $(xcrun --show-sdk-path --sdk macosx) -i $filename
The “Code Template:” field should contain the code you want to start with when you create a blank Swift file in CodeRunner.
In the “File Extension” field, enter swift.

Command Line Tool - Error - xcrun: error: unable to find utility "xcodebuild", not a developer tool or in PATH

I am getting this error while building the SwiftJSON framework to the Some Xcode project through Carthage Dependency Manager.

failed with exit code 72:
xcrun: error: unable to find utility "xcodebuild", not a developer
tool or in PATH
I solved that problem by setting the Command Line Tools in Xcode. Go to:
Xcode > Preferences > Locations
And select the command line tool from the dropdown. If you have only one version of Xcode installed, there should be only one option. If you have several versions of Xcode, then you must choose the one you need.
Update (added image for reference)
The simplest fix is from CLI:
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
(this should be path to your Xcode.app)
By the way this can happen even if you have only one version of Xcode . It happens when you instal homebrew before the first Xcode installation (which makes sense because you may want to install Xcode through mas install 497799835 and mas needs homebrew).
Following command worked for me
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

swift build doesn't work

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}"

How to install Swift package via package manager?

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.

Debug ios Problems in command line- Xcode

I built a project to iPhone and debugging it in Xcode 4.3.2 works fine. However, I want to debug it in command line, so I run:
xcodebuild -target NAMEOFTARGET -sdk SDKPATH -configuration Release
it should be the same as in Xcode, but I'm getting some errors and it does not compile! Maybe someone could help...

It's looking for GCC in /opt/ and not finding it. That's not a standard installation location for the GCC bundled with Xcode. The following command will tell you where Xcode is looking for its developer tools:
xcode-select -print-path
To change it, run:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
That path is for the standard Xcode installation location as installed through the App Store. If you've installed it elsewhere, you'll have to alter the path accordingly.
