仮の解決方法?? | Temporary solution??

Unityで書き出し先に指定したフォルダにはXcodeのプロジェクトが書き出されていました。
The Xcode project was exported to the folder specified as the export destination in Unity.

そのパスを指定してpod installを実行することでLINE SDKをCocoaPodsで導入できました。
I was able to install the LINE SDK with CocoaPods by running pod install with that path.

実機で実行できました。
I was able to execute it on the actual machine.

更なる問題 | Further problems

一時的な解決策が分かったので既存のプロジェクトに導入しようとチャレンジしました。
I found a temporary solution, so I tried to introduce it into an existing project.

ただしpod installしてもXcodeのビルドはエラーが出ました。
However, even with pod install, I got an error when building Xcode.

こちらが新規プロジェクトの場合のPodfileです。
Here is the Podfile for a new project.

platform :ios, '10.0'

target 'Unity-iPhone' do
    use_frameworks!
    pod 'LineSDKSwift/ObjC', '~> 5.1'
end

target 'UnityFramework' do
    use_frameworks!
    pod 'LineSDKSwift/ObjC', '~> 5.1'
end

こちらが既存のプロジェクトに追加した場合のPodfileです。
Here is the Podfile when added to an existing project.

Hi,

Thanks for reporting this.

The CocoaPods building script of LINE SDK for Unity does quite a few things, including adding LINE SDK pod entry to Podfile, installing it, and also set up other necessary build settings automatically. Most of these require you have a valid Ruby environment. Your first attempt to install it in an empty exported project seems to be related to Ruby permission.

The system-bundled Ruby always installs gems under a system path, which requires your password for sudo. It is an obstacle of the automation process. So we are asking LINE SDK for Unity users to have a managed Ruby version. You can use either rbenv or rvm to install a version of ruby in the user path, so other gem installation does not require further permission. Can you try to follow the guide here, specifically, in the "Ruby Environment" section, to prepare a valid Ruby environment?

And for your existing project, it seems that you already have other CocoaPods dependencies. LINE SDK for Unity now requires to build as framework and linked in a dynamic way, so use_frameworks! is necessary. I am not sure about Firebase's requirement, but I guess it should be fine for them to link as dynamic (you can try to add use_frameworks! to your existing project to see how it works). If that is true, once you can prepare a valid Ruby environment, the build should run seamlessly.

However, if your existing pod dependencies requires to build as a library and linked in a static way, LINE SDK for Unity won't work now. In this case, maybe you can consider switching to another integrating way, Carthage, which is less invasive to your existing project:

CocoaPods is the default, recommended dependency manager used by LINE SDK for Unity. However, it requires a slightly different project structure than what you might be used to. Also, if your project is already using CocoaPods for another purpose, you may be forced to use Carthage. Choose the dependency manager that works best for you and your project.

You can find more instruction and comparison of two on the same page. To switch the dependency manager used, check the Settings for iOS export.

私はCarthageを使用しようと思います。
I'm going to use Carthage.

操作としては、Unityの「Preferences... > LINE SDK」からiOS Dependency Managerにて「Carthage」を選択しました。
As an operation, I selected "Carthage" in iOS Dependency Manager from "Preferences ...> LINE SDK" of Unity.

UnityでBuild and Runした際のエラーがこちらです。
Here is the error when building and running in Unity.

Building universal frameworks with common architectures is not possible. The device and simulator slices for "LineSDK" both build for: arm64

Ummm,

That is an issue of Carthage which fails to build a framework for Xcode 12 (see here and here). I will check how can I make it easier to adopt.

Stay tuned.

[onevcat]

Hey,

A workaround for this has been applied in #30.

Here is a beta version and maybe you can give it a try, in which the Carthage building failure should be fixed.

line_sdk_unity_1.1.5_beta.1.zip

[consolesoup]

私はこれを試しました。結果として成功しました。
I tried this. As a result, it was successful.

Firebaseの件はこれと別件のIssueだと思います。新規で作成しても良いですか？
I think the Firebase issue is another issue. Can I create a new one?

[onevcat]

To install LINE SDK with Firebase (or any other libraries requiring CocoaPods as a dependency manager) would be tricky. It is mainly Unity to blame for the lack of a standard dependency manager.

But, yes. Feel free to open a new issue and we can check and find if there is a good solution for it.

[onevcat]

The changes in #30 will be contained in the 1.1.5 release soon.

I am closing this now.
