[zzzzzyijie]

it will crash on iOS11/12 because of this code:

version: 6.18.0 #if swift(>=5.5) @available(iOS 13.0, macOS 10.15, tvOS 13.0, watchOS 6.0, *) public extension Guarantee { func async() async -> T { await withCheckedContinuation { continuation in done { value in continuation.resume(returning: value) } } } }

@available(iOS 13.0, macOS 10.15, tvOS 13.0, watchOS 6.0, *) public extension Promise { func async() async throws -> T { try await withCheckedThrowingContinuation { continuation in done { value in continuation.resume(returning: value) }.catch { error in continuation.resume(throwing: error) } } } } #endif

Hello @zzzzzyijie Please provide more details.

What does the crash say? Something generic like EXC_BAD_ACCESS or something more specific?
