CocoaPodsへのライブラリのアップロードと注意点

Last updated at Posted at 2016-10-12

はじめに

CocoaPodsへライブラリを公開するにあたり、気をつける点と簡単な手順まとめておきます。

実行環境

  • OS X El Capitan 10.11.5
  • git version 2.8.4 (Apple Git-73)
  • CocoaPods 0.39.0 ※後述
  • Xcode Version 8.0

CocoaPodsへのライブラリのアップロードの手順

1. ライブラリの雛形作成

$ pod lib create [Library name]

2. ライブラリ、Exampleの実装

3. podspecファイルの修正

4. Githubに公開

4.1. Githubpush

$ git add .
$ git commit -m "commit message"
$ git remote add origin https://github.com/[User name]/[Library name].git
$ git push origin master

4.2. タグをつけてGithubpush

$ git tag 0.1.0
$ git push --tags

5. podspecのバリデーションを行う

$ pod spec lint LibraryName.podspec

6. CococaPodにアカウント登録

$ pod trunk register [your mail address] [your name]

ここでCococaPodからメールが来るので確認する。

$ pod trunk me

で情報が表示されればOK

7. CocoaPodsに公開

$ pod trunk push LibraryName.podspec 

ここまで、簡単にCocoaPodsでライブラリの作成から公開までの簡単な手順です。
何も問題なければ簡単にできると思います。

注意点、はまったこと

今回いくつかのエラーではまっていたので、エラー内容と解決策をまとめておきます。

1. xcodebuildのエラー

$ pod spec lintでのバリデーションエラー

エラー内容

- ERROR | [iOS] xcodebuild: Returned an unsuccessful exit code.
    - NOTE  | [iOS] xcodebuild:  xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

解決策

CommandLineToolsにXcodeのバージョン指定がなければ、エラーが出るようです。

Xcode/Preferences/Locations/CommandLineToolsでXcodeのバージョンを指定する

2. Use Legacy Swift Language Version

$ pod spec lintでのバリデーションエラー

=== CLEAN TARGET LibraryName OF PROJECT Pods WITH THE DEFAULT CONFIGURATION (Release) ===

Check dependencies
“Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

    - ERROR | [iOS] xcodebuild: Returned an unsuccessful exit code.

Analyzed 1 podspec.

[!] The spec did not pass validation, due to 1 error.

解決策

podのバージョンを 1.1.0.rc.2に指定して、.swift-versionファイルにバージョン番号を指定してあげれば解決できます。

$ echo 2.3 > .swift-version

or

$ echo 3.0 > .swift-version

.swift-versionを作成したらgitpush

CocoaPodsのバージョンが0.39.0なので1.1.0.rc.2に変更

$ gem uninstall cocoapods
$ gem install cocoapods -v 1.1.0.rc.2

参考: Swift 3 & CocoaPods

3. pod trunk pushでのエラー

$ pod trunk push LibraryName.podspec

エラー内容


### Error

NoMethodError - undefined method `swift_version=' for #<Pod::Validator:0x007f89ab9224f8>

解決策

CocoaPodsのバージョンを最新1.1.0.rc.3に変更

$ gem uninstall cocoapods
$ gem install cocoapods -v 1.1.0.rc.3

終わりに

今回、CocoaPodsSwiftのバージョンの問題でエラーが出てたと思います。メジャーバージョンアップの際には特にバージョンに意識することが必要ですね。
