- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我在 iOS 14 上使用 SwiftlySearch,在 iOS 15 上使用 .searchable。
struct CompatibleSearchBarModifier: ViewModifier {
@Binding var text: String
@ViewBuilder
func body(content: Content) -> some View {
if #available(iOS 15.0, *) {
content.searchable(text: self.$text, prompt: "Placeholder")
} else {
content.navigationBarSearch(self.$text, placeholder: "Placeholder", hidesSearchBarWhenScrolling: true, cancelClicked: {text = ""})
}
}
}
基于 Crashlytics,应用程序在 iOS 14.7.1-14.8 设备上崩溃。不幸的是,我无法在 Xcode 13.2.1 上重现该问题,因为我无法在模拟器上使用这些 iOS 版本(我试过这个库但没有成功:https://github.com/JinjunHan/iOSDeviceSupport)。在这种情况下我能做什么?

最佳答案
更新:这已在 XCode 13.3 上修复。请更新到那个版本。如果你不想更新,我会在下面留下我的答案。
我的应用程序也遇到了同样的问题,用户报告在 iOS 14 上随机崩溃,我的崩溃日志看起来与您的非常相似。帮助我找到解决方案的主线是 __swift_instantiateConcreteTypeFromMangledName
(它在您的崩溃报告的第 6 行和我的第 7 行)。

经过一些挖掘,我发现这个崩溃报告是由于 Xcode 13.2 和 13.2.1 上的 Swift 编译器中的一个错误。
论坛帖子:https://developer.apple.com/forums/thread/697070
这里的主要问题是,在发布版本中使用 #if available
(使用在您的情况下可搜索的任何 iOS 15 特定 API)会破坏 iOS 14 及以下版本的 SwiftUI 应用程序。 Apple 已意识到此错误,目前没有官方的解决方法。
论坛帖子中一些用户建议的解决方法是:
-Onone
我使用了 Github 链接中提供的解决方法,但如果您想使用 -Onone
路线,我在下面提供了说明。
如何设置-Onone
All
优化
Swift Compiler - Code Generation
下,将发布部分的 Optimization Level
设置为 -Onone
。如果您不想设置编译器选项,这是我对您的问题的解决方案,您将收到 Xcode 警告,但暂时忽略它:
struct CompatibleSearchBarModifier: ViewModifier {
@Binding var text: String
@ViewBuilder
func body(content: Content) -> some View {
if #available(iOS 15.0, *) {
Group {
if #available(iOS 15.0, *) {
content.searchable(text: self.$text, prompt: "Placeholder")
}
}
} else {
content.navigationBarSearch(self.$text, placeholder: "Placeholder", hidesSearchBarWhenScrolling: true, cancelClicked: {text = ""})
}
}
}
我建议向 Apple 发送反馈助理报告,以便他们可以仔细查看此错误。
我希望 Apple 在 Xcode 13.3 或其他 13.2.x 更新中修复此问题。
