【Flutterのエラー】解決済み「Unable to find a target named RunnerTests in project Runner.xcodeproj, did find Runner.」

エラー・警告

はじめに

古めのプロジェクトを新しいバージョンのFlutterをiOSで実行時に、以下のエラーが発生した。調査して、修正した。

Using `ARCHS` setting to build architectures of target `Pods-Runner`: (``)
[!] Unable to find a target named `RunnerTests` in project `Runner.xcodeproj`, did find `Runner`.

結論

Podfileの以下の箇所を削除する。

  target 'RunnerTests' do
    inherit! :search_paths
  end

解説

今ではXCodeのプロジェクトにTarget「RunnerTests」が最初から追加される。しかし古いプロジェクトには、「RunnerTests」がなかった。
新しくflutter pub getでPodfileを生成すると、「RunnerTests」がある前提で作成される。しかし古いプロジェクトにはないので、エラーになる。
ネットで調べると2つの方法が見つかった。

  • target「RunnerTests」を作成する
  • 「RunnerTests」の読み込みをなくす

後者を採用。だって楽だもん。
そちらで対応したのが「結論」。前後を含めるとPodfileは以下のようになっている。

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
-  target 'RunnerTests' do
-    inherit! :search_paths
-  end
end
