When using Swift toolchain from Xcode 15.0 | Beta 6 | 15A5219j, not the Self built toolchain, this file can be compiled successfuly without crash

The strange is that, Apple's close-sourced Swift does not generate any diagnostics, but when using the Self-built xctoolchain, it try to generate some warning and crash.🤔️

[dreampiggy]

Seems this will generate a warning for the API call to .autocapitalization(.none)

This mark deprecated on iOS 16.1: https://developer.apple.com/documentation/swiftui/view/autocapitalization(_:)/

But the Class marked availability as iOS 16.0.

Is this warning caused by this SDK declaration ? But why Apple's close-sourced Swift does not trigger any warning ?

    @available(iOS, introduced: 13.0, deprecated: 100000.0, message: "use textInputAutocapitalization(_:)")

@dreampiggy After building the "swift 5.9" source in release mode, I get a similar error when building the code below.

• Xcode version : 15.0

import CloudKit
public class sample {
	private static let recordType = "sample"
	private func test() {
		 let sub = CKQuerySubscription(recordType: Self.recordType,
                                     predicate: NSPredicate(value: true),
                                     options: .firesOnRecordUpdate)
	} 
}

CKQuerySubscription init function is deprecated on iOS 10.0.
(ref : https://developer.apple.com/documentation/cloudkit/ckquerysubscription/4134972-init)
If you change the deprecated code as shown below, no error will occur.

import CloudKit
public class sample {
	private static let recordType = "sample"
	private func test() {
		 let sub = CKQuerySubscription(recordType: Self.recordType,
                                     predicate: NSPredicate(value: true), 
                                     subscriptionID: "sample", 
                                     options: .firesOnRecordUpdate)
	} 
} 
}

This crash is related to that #68034 because of non exists platform visionOS

This crash is related to that #68034 because of non exists platform visionOS

Yes, "memory error" occurs if this is a release build, or "bad PlatformKind” if this is a debug build.
