When I annotate the closure with Sendable, the crash no longer occurs.
let singularConfig = SingularConfig(apiKey: "xxx", andSecret: "yyy")
singularConfig.singularLinksHandler = { @Sendable params in
// works fine
}Question
Could you please update the SDK so that the handler is correctly marked Sendable (or otherwise compatible with Swift 6)?
Environment
- Singular SDK version: 12.8.1
- Xcode version: 16.2
- Swift version: 6.0
