SwiftUIのPickerでLabelを表示しない方法です。 labelsHidden を設定することで可能です。 参考: How to hide the label of a Picker, Stepper, Toggle, and more using labelsHidden() (adsbygoogle = window.adsbygoogle || []).push({}); amzn_assoc_ad_type ="responsive_search_widget"; amzn_assoc_tracking_id ="swiswiswift-22"; amzn_assoc_marketplace ="amazon"; amzn_assoc_region ="JP"; amzn_assoc_placement =""; amzn_assoc_search_type = "search_widget";amzn_assoc_width ="auto"; amzn_assoc_height ="auto"; amzn_assoc_default_search_category =""; amzn_assoc_default_search_key ="";amzn_assoc_theme ="light"; amzn_assoc_bg_color ="FFFFFF";

SwiftUI で Picker を表示するサンプルです。 参考: Is there a way to call a function when a SwiftUI Picker selection changes?
