@Guang1234567 Hi, thank you for your reply.

I have installed macOS 10.14.6 on a virtual machine with Xcode 11.3.1 and all tests run successfully. However, I can't run tests with swift test on a terminal, because I get this error: is using Swift tools version 5.2.0 but the installed version is 5.1.0.

Could you please provide additional information:

• what Xcode version do you use?
• have you tried to run tests using Xcode but not on a terminal with command swift test?
• do you receive this error every time you run tests?
• is the computer where you run tests 64-bit? (because 32-bit is not supported)

Thank you and waiting for you reply.

Sorry about that i didn’t provided the env’s detail of this bug.

The step that reproduce the problem ( everytime):

1. Modify the Package.swift to change the swift-tools-version-5.2 to swift-tools-version-5.1

2. install swift-5.1.5-RELEASE from swift.org

3. rm -rf .build/x86_64-apple-macosx

4. /Library/Developer/Toolchains/swift-5.1.5-RELEASE.xctoolchain/usr/bin/swift test

Thanks.

In addition, i also drop the Combine for Swif-Android-Toolchain-5.2.3 to support android platform.

But i think it's not bussiness about that bug, because master and release_2.1.2 branch also reproduce the problem

My fork is here:

Note: Without_Combine branch

BTW, i also try the swift-5.2.3-RELEASE, but all unittest passed O(∩_∩)O hahaha!

The step:

1. Modify the Package.swift to change the swift-tools-version-5.2 to swift-tools-version-5.1

2. install swift-5.2.3-RELEASE from swift.org

3. rm -rf .build/x86_64-apple-macosx

4. /Library/Developer/Toolchains/swift-5.2.3-RELEASE.xctoolchain/usr/bin/swift test

Thanks.

@Guang1234567 I reproduced this issue following your steps on Swift 5.1.5. It's really strange because when I run tests on Xcode 11.3.1 with Swift 5.1.3 everything is okay. Also want to highlight that Swift 5.1.5 is for Linux usage but not for macOS.

I experimented and found out that most probably the problem is in @inlinable, which I use for better performance and don't plan to drop it. That's why I will increase the minimal required version of Swift to 5.2.

Currently, I am planning to support only the latest Swift version, as I have no possibility to always test on previous versions.

Thank for reaching out. If the issue with Swift 5.1.5 is really critical for you, please let me know.

@belozierov

The issue with Swift 5.1.5 is not really critical for me, hahaha.

Thanks.

But could you use OpenCombine instead of Combine if you have time off, hahaha.

That will save someone’s time who works on Linux and Android and macOS. 😁
