Chatwork株式会社 モバイルアプリケーション開発部 中山 龍 2024年4月19日 - mobile.stmn #5 効率化に挑戦してみたら モバイル開発が少し快適になった話

自己紹介 中山 龍 (なかやま りゅう) ● Chatwork株式会社 ○ 新卒2年目のiOSエンジニア(21) ● フルリモート勤務で愛知県在住 2 @ryu_develop 先週、発熱で寝込んでいたときに茶碗蒸しの美味しさ に目覚めました。 (作るのにも挑戦していますが、美味しくできないので、良い 出汁など知っている方は懇親会で教えてください)

モバイル開発をしていると 「この作業めんどくさいな...」 「人力でやらなくてもな...」 という場面があると思います

そんな面倒な作業をいろいろ解決してみたら いいことがあったので2つほど紹介します！ 先に言っておきますが、最近はPrivacy Manifestsおじさんをやっ ているので、その内容がメインです🙏

Appleから届いた警告メールをいい感じにする 1

どのようにした？ 8 この課題を解決するために... 警告メールを入力して、必要な情報を出力するMacアプリ を作成しました 内容は実際のアプリとは関係ありません

どのようにした？ 9 この課題を解決するために... 警告メールを入力して、必要な情報を出力するMacアプリ を作成しました 警告メール 内容は実際のアプリとは関係ありません

どのようにした？ 10 この課題を解決するために... 警告メールを入力して、必要な情報を出力するMacアプリ を作成しました 必要な情報 内容は実際のアプリとは関係ありません

どうやって作ったか 11 SwiftUIで画面を作り、Swiftで正規表現を使って必要な部分だけを抜き出す処 理をして、結果を表示している 🎉iOS開発者におなじみの技術で作られている！🎉 しかも、個人利用想定なので、OSのバージョンも気にせずに最新技 術を使える 💡モバイルエンジニアでも手軽に手を出しやすい

参考・注意 GitHub: https://github.com/Ryu-nakay/privacy-manifests-warning-email-formatter 12 ※ プライベートな時間で作成したものであり、所属組織とは一切関係ありません

Spreadsheetの設定値からPrivacyInfo.xcprivacyを 生成する 2

解決したい課題 14 解決したい課題: Xcode上でのPrivacy Manifestsファイルの編集作業に問題・不満が ある あまり「編集しやすい」とは言えない使い 心地 コメントが書けないので、その設定値を入 れた背景などを残せない (ドキュメント性がない) 別で設定値の背景を記すためのドキュメ ントを用意しても ● 設定値の反映がとても面倒 ● 書き写しのミスが起こるかも ● 別管理なのでそもそも見つからない かも

どのようにした？ 15 この課題を解決するために... Spreadsheetの設定値からPrivacy Manifestsファイルを生成するプログラム を作成しました GAS 設定画面

どのようにした？ 16 この課題を解決するために... Spreadsheetの設定値からPrivacy Manifestsファイルを生成するプログラム を作成しました 設定画面 4つの設定シートがあるので各種設定値 を入力する ● 『備考』の列があるのでそこにコメン トを残せる ● セルの編集履歴が見れる

どのようにした？ 17 この課題を解決するために... Spreadsheetの設定値からPrivacy Manifestsファイルを生成するプログラム を作成しました ダウンロードボタンを クリックする 表示されるウインドウの『ダウンロード』を押す と、ファイルがダウンロードされる

どうやって作ったか 18 claspを使ってGoogle App ScriptsのプログラムをローカルのTypeScriptで 書き、連携されたGoogle Spreadsheetsで設定値を入力する 🎉Spreadsheetsとも連携でき、複数人同時にも操作できる🎉 しかし、モバイル開発にはあまり馴染みのない言語 / 技術であり少 し学習は必要 💡ドキュメント性を持たせられる 💡 複数人での使用も手軽に実現できる

参考・注意 一般公開するかは検討中 19 ※ プライベートな時間で作成したものであり、所属組織とは一切関係ありません

他にもネット記事を参考にしながら ● サードパーティSDKのPrivacy Manifests対応状 況を自動で調査するプログラム ● required reason APIを使用していないかを調査 するプログラム を作成しました

実際にこれらを作ってみて... TITLE タイトル

実際にこれらを作ってみて... 22 利用者として 「人力だと数分かかるな〜」という作業が一瞬で終わったり、プログラムが自 動でやってくれている間に他の作業を進められたり、嬉しいことがあった 「リソースの余裕的にこれがなかったらできてなかっただろうな」というような 念の為の確認作業を行えたりと、作業を行うハードルが下がる

実際にこれらを作ってみて... 23 開発者・導入者として 複数の人が定期的に行う面倒なことを自動化・便利にするツールを作成する と、開発したものの恩恵が大きく、さらにメンバーからの評判が良いと嬉しい 個人として開発したものに関しては、SNSで共有した際に反響があると、同 業者の助けになれたような気がするので自己肯定感が上がる・嬉しい 自分で作ったもので業務の効率化がうまくいくと、さらに作りたいモチベー ションが上がり、効率化のおかげで業務がしやすくなる (まだ便利になったと言えるほど運用はできていないが)

24 ということで、より快適に・便利にモバイルアプリを開発するた めに、モバイル以外の開発で効率化にチャレンジしてみたとい うことの共有でした！

働くをもっと楽しく、創造的に
