I am running into the same problem, any pointers will be good in resolving this. I am also running on xcode 8 beta.

[GJNilsen]

Perfect has probably not been rewritten for Swift 3 yet, and Xcode 8 is pretty buggy, so being a bit patient is my advice.

[taplin]

While the master branch of Perfect builds for Swift 3 on the June 6 snapshot, the Xcode8 beta introduced some unexpected issues which have not been resolved yet.

[kjessup]

Yes, we have supported Swift 3.0 for a good while now and update for every snapshot as soon as possible. However, we are seeing a problem with the version included in Xcode 8. After updating the code to compile with this new version on the command line with SPM, the generated Xcode projects do not compile. We are holding off on tagging the updated code for now.

We continue to compile with the 3.0 DEVELOPMENT-SNAPSHOT-2016-06-06-a toolchain for the time being.

[rymcol]

https://github.com/kylef/swiftenv helps enormously to manage this against different projects.

[JoeFerrucci]

I'm having a similar issue. I tried the latest Swift 3.0 with Xcode 8 Beta, and also DEVELOPMENT-SNAPSHOT-2016-05-09-a. -- I am running swiftenv.

Here is my terminal log that shows cloning the PerfectTemplate and then attempting to run swift build

[rymcol]

@JoeFerrucci make sure you go into Xcode and set command line tools to Xcode 8, then make sure you check out the master branch of perfect in git.

[iamjono]

I agree with @rymcol - that's likely the difference as it's all working for me on Xcode 8 beta and default Swift 3 install from that, and using the command line tools for Xcode 8.

Closing for now, please reopen if the issue remains. Thanks!

[sunlyear]

I am having exactly the same issue @JoeFerrucci. Could not solve it at all.

[iamjono]

@sunlyear have you selected both settings as mentioned in https://github.com/PerfectlySoft/Perfect readme? Also can you post the exact version of Xcode and Swift that you are using please. Thanks!

[sverrisson]

I had the same issues while following the instructions and compiling from the Terminal. I solved it by packing for Xcode: swift package generate-xcodeproj and compiling the project in Xcode.

[jordonedavidson]

Similar issue for me: `Jordons-MacBook-Pro:PerfectTemplate jordondavidson$ swift build Compile Swift Module 'PerfectThread' (2 sources) /Users/jordondavidson/GITRepos/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:210:97: error: cannot convert value of type 'UnsafeMutablePointer' (aka 'UnsafeMutablePointer<()>') to expected argument type 'UnsafeMutablePointer<>' let unleakyObject = Unmanaged.fromOpaque(UnsafeMutablePointer(p)).takeRetainedValue() ^ /Users/jordondavidson/GIT_Repos/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:233:37: error: value of type 'Unmanaged' has no member 'toOpaque' let leakyObject = Unmanaged.passRetained(holderObject).toOpaque()

I've updated the tools location as instructed.

xcode Version 8.0 beta (8S128d)
Apple Swift version 3.0 (swiftlang-800.0.30 clang-800.0.24)

[jordonedavidson]

Additionally I tried the Xcode method but the following build errors occurred:

/Users/jordondavidson/GIT_Repos/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:210:97: Cannot convert value of type 'UnsafeMutablePointer<Void>' (aka 'UnsafeMutablePointer<()>') to expected argument type 'UnsafeMutablePointer<_>'
/Users/jordondavidson/GIT_Repos/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:233:37: Value of type 'Unmanaged<IsThisRequired>' has no member 'toOpaque'

I've been following the instructions outlined on the website's getting started page

[kjessup]

swift --version should report Apple Swift version 3.0 (swiftlang-800.0.33.1 clang-800.0.31)

The Xcode > Preferences > Locations CLI Tools should say: Xcode 8.0 (8S162m)

The Xcode app menu "Toolchains" submenu should either not be present (because you only have the default chain installed) of should be set to "Xcode 8.0".

xcodebuild -version should report:

Xcode 8.0
Build version 8S162m
