Issue
I am using SwiftlySearch on iOS 14 and .searchable on iOS 15.
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 = ""})
}
}
}
The app crashes on iOS 14.7.1-14.8 devices based on Crashlytics. Unfortunately, I can’t reproduce the problem on Xcode 13.2.1 since I can’t use these iOS versions on the simulator (I tried this library without any success: https://github.com/JinjunHan/iOSDeviceSupport). Any ideas what could I do in this situation?

Solution
UPDATE: This is fixed on XCode 13.3. Please update to that version. If you don’t want to update, I will leave my answer below.
I also had the same issue with my app where users reported random crashes on iOS 14 and my crash log looked very similar to yours. The main line that helped me find the solution was __swift_instantiateConcreteTypeFromMangledName (which is on line 6 of your crash report and line 7 on mine).
My crash report from simulator:

After some digging, I found that this crash report is due to a bug in the Swift compiler on Xcode 13.2 and 13.2.1.
Forum post: https://developer.apple.com/forums/thread/697070
The main issue here is that using #if available (with any iOS 15 specific API which is searchable in your case) in a release build breaks the application for iOS 14 and below with SwiftUI. Apple is aware of this bug and there are no official workarounds at the moment.
Some user-suggested workarounds from the forum post are:
- Use Xcode 13.1
- Change the swift compiler to use
-Ononeon release builds - Use this workaround https://github.com/gongzhang/swiftui-availability-check-crash
I used the workaround provided in the Github link, but if you want to go the -Onone route, I’ve provided instructions below.
How to set -Onone
- Go to your app target
- Go to that target’s build settings
- Select
Allin the top bar - Search for
optimization - Under
Swift Compiler - Code Generation, set theOptimization Levelto-Ononeunder the release section.
Here’s my solution to your problem if you don’t want to set compiler options, you’ll get an Xcode warning, but ignore it for now:
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 = ""})
}
}
}
I’d recommend sending a Feedback Assistant report to Apple so they can take a closer look at this bug.
I hope Apple fixes this issue in Xcode 13.3 or another 13.2.x update.
