<code>UITextField</code> の<code>becomeFirstResonder</code> みたいなことがやりたい。

<h2 id="%E5%8F%82%E8%80%83">

<a href="https://github.com/siteline/SwiftUI-Introspect" target="_blank" rel="nofollow noopener noreferrer">SwiftUI-Introspect</a> を使ったところ、期待通りに動作した。
<div class="code-block-container"><pre class="language-swift"><code class="language-swift">import Introspect
</code></pre></div><div class="code-block-container"><pre class="language-swift"><code class="language-swift">TextField("", text: $value)
.introspectTextField { textField in
 DispatchQueue.main.asyncAfter(deadline: .now() + 0.2, execute: {
 textField.becomeFirstResponder()
 })
}
</code></pre></div>
