[minlite]

Attaching minimal reproducible example of the crash.

Please note that you need to add your own amplifyconfiguration.json and awsconfiguration.json to the project before running. I've deleted these files before uploading as they are sensitive for my project. Additionally, ensure that you are running the project on a device with iOS 18.1 Beta (22B5007P) installed. This issue is not reproducible on simulators.

I've noticed this issue also happening in Line 204 of URLSessionHTTPClient.swift in smithy-swift:

/smithy-swift/Sources/ClientRuntime/Networking/Http/URLSession/URLSessionHTTPClient.swift

    public func send(request: SdkHttpRequest) async throws -> HttpResponse {
        return try await withCheckedThrowingContinuation { continuation in <--- CRASH HERE EXC_BAD_ACCESS

Since this issue does not happen on Xcode 16 beta 4 (16A5211f), it's starting to look like an Xcode regression to me so I have filed a radar with Apple as well (FB14768097)
