[XCTest] Cannot build using XCode

Hi All,

I am new to this forum.

I am trying to build the xctest project. I followed the instructions at

I am able to successfully build via the build scripts. But, if I build
XCTest using xcode using the SwiftXCTest scheme I am getting a few errors.

1. swift-corelibs-foundation/Foundation/NSXMLDTDNode.swift:242:64: error:
cannot convert value of type 'UnsafeMutablePointer<Void>' (aka
'UnsafeMutablePointer<()>') to expected argument type 'OpaquePointer'
            let unmanaged = Unmanaged<NSXMLDTDNode>.fromOpaque(privateData)

2. swift-corelibs-foundation/Foundation/NSTimer.swift:14:47: error: cannot
convert value of type 'UnsafeMutablePointer<Void>' (aka
'UnsafeMutablePointer<()>') to expected argument type 'OpaquePointer'
    let t = Unmanaged<NSTimer>.fromOpaque(info!).takeUnretainedValue()

etc.

My dev environment,
OS: Mac OSX El Capitan 10.11.4 (15E65).
Xcode Version: Version 7.3.1 (7D1014)
XCode Toolchain: Swift Development Snapshot 2016-05-09 (a)

Any help is appreciated.

Madhu

That's right, breaking changes have been made to Swift since the latest
toolchain snapshot was released, and Corelibs Foundation has been updated
accordingly.

Until the next snapshot, an alternative to building your own toolchain
would be to check out an older commit of Foundation which still builds with
the compiler in the snapshot toolchain, since XCTest doesn't depend on any
of the more recent Foundation changes. I've had success using this commit:

Madhu,

Oy, my bad -- I only just noticed you put the toolchain version at the
bottom of your original email.

It's possible the May 9th toolchain is already too old to build XCTest.
I'll double-check myself. In the meantime, you may want to try building
your own toolchain and using that.

Madhu,

Thanks for the report!

The main difference between the build scripts (which use xcodebuild) and
using Xcode itself is the version of Swift that is used. The build scripts
build a Swift 3.0 compiler, then use that to build XCTest. When using Xcode
directly, you need to select a recent Swift toolchain yourself.

Which Swift toolchain are you using to compile XCTest in Xcode?

Our tests only make sure apple/swift master works. If the latest Swift
toolchain from http://swift.org doesn't work, you may have to built your
own toolchain. You can do so using the `utils/build-toolchain` script in
the Swift repository.

Once you figure out your Swift toolchain version, let us know! You should
be able to find out in the preferences pane in Xcode.

Wow, that was a quick response. Thanks Brian Gesiak and Brian Croom.

My first quick attempt using build-toolchain script to build my own tool chain failed. Anyway I will give it another try and let you know the status.

So after spending almost a week trying to build swift and core libraries
(mainly xctest) during the end of May un-successfully, I made up my mind to
give another attempt today.

I checkout the latest code from swift repo. Since the xctest documentation
says, "Confirm you're able to build the Swift project using
utils/build-script -R", that's where I started.

Unfortunately, build-script -R gives the below error.

<unknown>:0: error: Swift does not support the SDK 'MacOSX10.11.sdk'

My active developer directory is
'/Applications/Xcode-beta.app/Contents/Developer'.
The toolchain is 'Xode 8.0'

The build is taken in Mac OSX El Capitan 10.11.4

Let me know whether I miss anything? I assume getting the build working for
the first time is the hardest, but there I am!

Any help is appreciated!

Madhu

Hmm, have you tried deleting your `build/swift-macosx-x86_64/` directory? I
wonder if cached CMake values could cause that issue.

(By the way, I can confirm that getting the build going for the first time
is the most challenging! I hope we can get things going for you soon.)

Madhu,
In addition the checking out the latest code in apple/swift, please run `utils/update-checkout`, in order to update the other repositories Swift depends upon.
I haven't been able to build OS X since Xcode 8 beta was required for the build, so I'm not sure about your specific error, unfortunately. Perhaps double-check that `xcode-select -print-path` prints out the path to Xcode 8...?

Yep, I checked out the latest cod using 'utils/update-checkout' and
xcode-select --print-path points to the XCode 8 beta.

I checkout the latest code from swift repo. Since the xctest documentation
says, "Confirm you're able to build the Swift project using
utils/build-script -R", that's where I started.

Unfortunately, build-script -R gives the below error.

<unknown>:0: error: Swift does not support the SDK 'MacOSX10.11.sdk'

My active developer directory is
'/Applications/Xcode-beta.app/Contents/Developer'.
The toolchain is 'Xode 8.0'

The build is taken in Mac OSX El Capitan 10.11.4

Let me know whether I miss anything? I assume getting the build working
for the first time is the hardest, but there I am!

Any help is appreciated!

Madhu,

Oy, my bad -- I only just noticed you put the toolchain version at the
bottom of your original email.

It's possible the May 9th toolchain is already too old to build XCTest.
I'll double-check myself. In the meantime, you may want to try building
your own toolchain and using that.

The main difference between the build scripts (which use xcodebuild)
and using Xcode itself is the version of Swift that is used. The build
scripts build a Swift 3.0 compiler, then use that to build XCTest. When
using Xcode directly, you need to select a recent Swift toolchain yourself.

Which Swift toolchain are you using to compile XCTest in Xcode?

Our tests only make sure apple/swift master works. If the latest Swift
toolchain from http://swift.org doesn't work, you may have to built
your own toolchain. You can do so using the `utils/build-toolchain` script
in the Swift repository.

Once you figure out your Swift toolchain version, let us know! You
should be able to find out in the preferences pane in Xcode.

Wow, the swift build is a success. Though there are a few warnings at the
end. I guess the issue was with cached values in the build directory.

But, in the next step to build xctest using "/utils/build-script --preset
corelibs-xctest", the build fails. The build error log is given below.

Hi Brian,

Thanks for you response.

Still I cannot compile corelibs-xctest with xcode-beta. It seems the error
is too generic to debug! If xctest is not yet configured against xcode 8
beta, probably, I will wait. At this point, I am lazy to create my own
toolchain, since my last attempt went bust!

The steps I followed

1. delete swift/build
2. utils/update-checkout
3. sudo xcode-select -s
/Applications/Xcode-beta.app/Contents/Developer
4. utils/build-script -r -t (success)
5. utils/build-script -R. (success)

So after spending almost a week trying to build swift and core
libraries (mainly xctest) during the end of May un-successfully, I made up
my mind to give another attempt today.

I checkout the latest code from swift repo. Since the xctest
documentation says, "Confirm you're able to build the Swift project using
utils/build-script -R", that's where I started.

Unfortunately, build-script -R gives the below error.

<unknown>:0: error: Swift does not support the SDK 'MacOSX10.11.sdk'

My active developer directory is
'/Applications/Xcode-beta.app/Contents/Developer'.
The toolchain is 'Xode 8.0'

The build is taken in Mac OSX El Capitan 10.11.4

Let me know whether I miss anything? I assume getting the build
working for the first time is the hardest, but there I am!

Any help is appreciated!

builds with the compiler in the snapshot toolchain, since XCTest
doesn't depend on any of the more recent Foundation changes. I've had

Madhu,

Oy, my bad -- I only just noticed you put the toolchain version at
the bottom of your original email.

It's possible the May 9th toolchain is already too old to build
XCTest. I'll double-check myself. In the meantime, you may want to try
building your own toolchain and using that.

Madhu,

Thanks for the report!

The main difference between the build scripts (which use
xcodebuild) and using Xcode itself is the version of Swift that is used.
The build scripts build a Swift 3.0 compiler, then use that to build
XCTest. When using Xcode directly, you need to select a recent Swift
toolchain yourself.

Which Swift toolchain are you using to compile XCTest in Xcode?

Our tests only make sure apple/swift master works. If the latest
Swift toolchain from http://swift.org doesn't work, you may have
to built your own toolchain. You can do so using the
`utils/build-toolchain` script in the Swift repository.

Once you figure out your Swift toolchain version, let us know! You
should be able to find out in the preferences pane in Xcode.

Hi Brian,

Thanks for you response.

Still I cannot compile corelibs-xctest with xcode-beta. It seems the error
is too generic to debug! If xctest is not yet configured against xcode 8
beta, probably, I will wait. At this point, I am lazy to create my own
toolchain, since my last attempt went bust!

The steps I followed

1. delete swift/build
2. utils/update-checkout
3. sudo xcode-select -s

4. utils/build-script -r -t (success)
5. utils/build-script -R. (success)

building your own toolchain and using that.

Hi All,

I am trying to build the xctest project. I followed the

Hmm, it does look like XCTest needs some work done to get things working
with the latest Swift 3 changes made in the stdlib and corelibs-foundation.
I don't have access to a development environment to investigate further,
but as far as I can tell, this wouldn't build on Linux either. Has there
been any indication of these issues from CI, I wonder?

Hi Brian,

Thanks for you response.

Still I cannot compile corelibs-xctest with xcode-beta. It seems the
error is too generic to debug! If xctest is not yet configured against
xcode 8 beta, probably, I will wait. At this point, I am lazy to create my
own toolchain, since my last attempt went bust!

The steps I followed

1. delete swift/build
2. utils/update-checkout
3. sudo xcode-select -s
/Applications/Xcode-beta.app/Contents/Developer
4. utils/build-script -r -t (success)
5. utils/build-script -R. (success)
6.
$ cd swift-corelibs-xctest

So after spending almost a week trying to build swift and core

my mind to give another attempt today.

I checkout the latest code from swift repo. Since the xctest
documentation says, "Confirm you're able to build the Swift project using
utils/build-script -R", that's where I started.

Unfortunately, build-script -R gives the below error.

<unknown>:0: error: Swift does not support the SDK 'MacOSX10.11.sdk'

My active developer directory is
'/Applications/Xcode-beta.app/Contents/Developer'.
The toolchain is 'Xode 8.0'

The build is taken in Mac OSX El Capitan 10.11.4

Let me know whether I miss anything? I assume getting the build

That's right, breaking changes have been made to Swift since
the latest toolchain snapshot was released, and Corelibs Foundation has
been updated accordingly.

Until the next snapshot, an alternative to building your own
toolchain would be to check out an older commit of Foundation which still
builds with the compiler in the snapshot toolchain, since XCTest
doesn't depend on any of the more recent Foundation changes. I've had
success using this commit:

Looks like our continuous integration server works fine:

Madhu, are you sure you're using the latest master branch commit on each of
the apple/swift repositories? Specifically, you should pull down the latest
changes on: swift, swift-llvm, swift-clang, swift-corelibs-foundation,
swift-corelibs-xctest, swift-llbuild, and swift-package-manager. The CI
server appears to be fine, so if you're seeing compilation errors, I think
you may be using code that is out of date.

2016-06-20 22:22 GMT-04:00 Madhu Samuel <madhusamuel@gmail.com>:

So after spending almost a week trying to build swift and core
libraries (mainly xctest) during the end of May un-successfully, I made up
my mind to give another attempt today.

I checkout the latest code from swift repo. Since the xctest
documentation says, "Confirm you're able to build the Swift project using
utils/build-script -R", that's where I started.

Unfortunately, build-script -R gives the below error.

<unknown>:0: error: Swift does not support the SDK 'MacOSX10.11.sdk'

My active developer directory is
'/Applications/Xcode-beta.app/Contents/Developer'.
The toolchain is 'Xode 8.0'

The build is taken in Mac OSX El Capitan 10.11.4

Let me know whether I miss anything? I assume getting the build
working for the first time is the hardest, but there I am!

Any help is appreciated!

Madhu

That's right, breaking changes have been made to Swift since
the latest toolchain snapshot was released, and Corelibs Foundation has
been updated accordingly.

Until the next snapshot, an alternative to building your own
toolchain would be to check out an older commit of Foundation which still
builds with the compiler in the snapshot toolchain, since XCTest
doesn't depend on any of the more recent Foundation changes. I've had
success using this commit:
Changes done to NSJSONSerialization to align with darwin code (#373) · apple/swift-corelibs-foundation@04d4f92 · GitHub

Madhu,

Oy, my bad -- I only just noticed you put the toolchain version
at the bottom of your original email.

It's possible the May 9th toolchain is already too old to build
XCTest. I'll double-check myself. In the meantime, you may want to try
building your own toolchain and using that.

Madhu,

Thanks for the report!

The main difference between the build scripts (which use
xcodebuild) and using Xcode itself is the version of Swift that is used.
The build scripts build a Swift 3.0 compiler, then use that to build
XCTest. When using Xcode directly, you need to select a recent Swift
toolchain yourself.

Which Swift toolchain are you using to compile XCTest in Xcode?

Our tests only make sure apple/swift master works. If the
latest Swift toolchain from http://swift.org doesn't work, you
may have to built your own toolchain. You can do so using the
`utils/build-toolchain` script in the Swift repository.

Once you figure out your Swift toolchain version, let us know!
You should be able to find out in the preferences pane in Xcode.

Thanks for getting back on that.

Just a quick check. I can get the latest master branch from all needed

Madhu, are you sure you're using the latest master branch commit on each
of the apple/swift repositories? Specifically, you should pull down the
latest changes on: swift, swift-llvm, swift-clang,
swift-corelibs-foundation, swift-corelibs-xctest, swift-llbuild, and
swift-package-manager. The CI server appears to be fine, so if you're
seeing compilation errors, I think you may be using code that is out of

I don't have access to a development environment to investigate further,

been any indication of these issues from CI, I wonder?

2016-06-20 22:22 GMT-04:00 Madhu Samuel <madhusamuel@gmail.com>:

So after spending almost a week trying to build swift and core
libraries (mainly xctest) during the end of May un-successfully, I made up
my mind to give another attempt today.

I checkout the latest code from swift repo. Since the xctest
documentation says, "Confirm you're able to build the Swift project using
utils/build-script -R", that's where I started.

Unfortunately, build-script -R gives the below error.

<unknown>:0: error: Swift does not support the SDK
'MacOSX10.11.sdk'

My active developer directory is
'/Applications/Xcode-beta.app/Contents/Developer'.
The toolchain is 'Xode 8.0'

The build is taken in Mac OSX El Capitan 10.11.4

Let me know whether I miss anything? I assume getting the build
working for the first time is the hardest, but there I am!

Any help is appreciated!

Madhu

That's right, breaking changes have been made to Swift since

Until the next snapshot, an alternative to building your own
toolchain would be to check out an older commit of Foundation which still
builds with the compiler in the snapshot toolchain, since
XCTest doesn't depend on any of the more recent Foundation changes. I've
had success using this commit:

Madhu,

Oy, my bad -- I only just noticed you put the toolchain version
at the bottom of your original email.

It's possible the May 9th toolchain is already too old to build
XCTest. I'll double-check myself. In the meantime, you may want to try
building your own toolchain and using that.

Madhu,

Thanks for the report!

The main difference between the build scripts (which use
xcodebuild) and using Xcode itself is the version of Swift that is used.
The build scripts build a Swift 3.0 compiler, then use that to build
XCTest. When using Xcode directly, you need to select a recent Swift
toolchain yourself.

Which Swift toolchain are you using to compile XCTest in Xcode?

Our tests only make sure apple/swift master works. If the
latest Swift toolchain from http://swift.org doesn't work,
you may have to built your own toolchain. You can do so using the
`utils/build-toolchain` script in the Swift repository.

Once you figure out your Swift toolchain version, let us know!
You should be able to find out in the preferences pane in Xcode.

Madhu, are you sure you're using the latest master branch commit on each of the apple/swift repositories? Specifically, you should pull down the latest changes on: swift, swift-llvm, swift-clang, swift-corelibs-foundation, swift-corelibs-xctest, swift-llbuild, and swift-package-manager. The CI server appears to be fine, so if you're seeing compilation errors, I think you may be using code that is out of date.

Still I cannot compile corelibs-xctest with xcode-beta. It seems the error is too generic to debug! If xctest is not yet configured against xcode 8 beta, probably, I will wait. At this point, I am lazy to create my own toolchain, since my last attempt went bust!

Hi All,
I am new to this forum.
I am trying to build the xctest project. I followed the instructions at GitHub - apple/swift-corelibs-xctest: The XCTest Project, A Swift core library for providing unit test support
I am able to successfully build via the build scripts. But, if I build XCTest using xcode using the SwiftXCTest scheme I am getting a few errors.
1. swift-corelibs-foundation/Foundation/NSXMLDTDNode.swift:242:64: error: cannot convert value of type 'UnsafeMutablePointer<Void>' (aka 'UnsafeMutablePointer<()>') to expected argument type 'OpaquePointer' let unmanaged = Unmanaged<NSXMLDTDNode>.fromOpaque(privateData)
2. swift-corelibs-foundation/Foundation/NSTimer.swift:14:47: error: cannot convert value of type 'UnsafeMutablePointer<Void>' (aka 'UnsafeMutablePointer<()>') to expected argument type 'OpaquePointer' let t = Unmanaged<NSTimer>.fromOpaque(info!).takeUnretainedValue()
etc.
My dev environment, OS: Mac OSX El Capitan 10.11.4 (15E65).Xcode Version: Version 7.3.1 (7D1014)XCode Toolchain: Swift Development Snapshot 2016-05-09 (a)
Any help is appreciated.
