LicensePlist: Build fails on Xcode 10.2(Swift 5.0)

Confirmed on both my personal environment and my CI (Bitrise) environment 🎉

Same problem happens on my environment too. It turns out that it seems to be an issue of APIKit which LicensePlist uses as a dependency.

I tried to fork APIKit, update its dependencies as well as Xcode settings; and then fork LicensePlist and update its dependencies to include my forked APIKit, then it worked well.

There’s already someone sent a PR to migrate APIKit to Swift 5, so hopefully it’ll be resolved soon.

Reference:

• My forked APIKit with updates: https://github.com/el-hoshino/APIKit/commits/master

• My forked LicensePlist with updates: https://github.com/el-hoshino/LicensePlist/commits/master

@el-hoshino

Thanks for the confirmation 👍

But BTW, DEVELOPER_DIR=/Applications/Xcode-10.1.app/Contents/Developer ←does it work for those who don’t have Xcode-10.1.app app in their /Application directory…?

No, but it is used for releasing new CocoaPods version, so there are no problems for normal users. Maintainer(only me, currently) should have Xcode-10.1.app app in their /Application directory.

I’ve released 2.5.0 and all problems have been fixed as far as I confirmed.

My environment

• macOS 10.14.4
• Installed Xcode versions
  • Xcode 10.2 (Default Command Line Tools)
  • Xcode 10.1

I prepared different build, and use it for CocoaPods build with Xcode 10.1:

https://github.com/mono0926/LicensePlist/blob/439d7ae9d7afe976228a7207bdee167ff4103182/Makefile#L8-L11

https://github.com/mono0926/LicensePlist/blob/2a2fcb1eacebe6696dcbaf3e65fa0a56411b9d19/Makefile#L29-L34

https://github.com/mono0926/LicensePlist/blob/2a2fcb1eacebe6696dcbaf3e65fa0a56411b9d19/release.sh#L70

It seems that the build result depends on Command Line Tools versions.

Xcode 10.1

$ swift --version
$ Apple Swift version 4.2.1 (swiftlang-1000.11.42 clang-1000.11.45.1)
$ Target: x86_64-apple-darwin18.5.0

Xcode 10.2

$ swift --version
$ Apple Swift version 5.0 (swiftlang-1001.0.69.5 clang-1001.0.46.3)
$ Target: x86_64-apple-darwin18.5.0

Build Result

.	Swift 4.2.1	Swift 5.0
with -Xswiftc -static-stdlib	✅	❌
without -Xswiftc -static-stdlib	✅	✅

https://github.com/mono0926/LicensePlist/blob/2d793f20da00f1128e4e168c2b7f9c7c9d03b3be/Makefile#L5-L6

But, without -Xswiftc -static-stdlib, the tool which is installed by CocoaPods doesn’t work on Xcode 10.1(Swift 4.2.1) or earlier(ABI not supported version) as written #103. So, I think it is prioritized.

I added about this to README.

I am using xcode 10.2.1 and installed it via brew without any problems.

I guess one of the workarounds we can do now is to deploy different versions for CocoaPods and Homebrew with different versions specified in .podspec file and formula file 😄

@mono0926 Found a similar problem here: https://github.com/grpc/grpc-swift/issues/416

Seems that it’s because Xcode no longer embeds Swift Standard Library 🤔

I tried installing through homebrew again and got the same error with 2.4.0.

However, I cloned the repository and ran make install and there were no problems. I will just use the version from source for now! Thanks!
