False positive: 'init(unsafeData:)' is unused

[RobinFarmer]

I have the following extension:

extension Array {
    init?(unsafeData: Data) {
        guard unsafeData.count % MemoryLayout<Element>.stride == 0 else { return nil }
        self = unsafeData.withUnsafeBytes { .init($0.bindMemory(to: Element.self)) }
    }
}

Which I use like this:

let bytes = [UInt8](unsafeData: byteData)!

however it's being reported as unused.

Unfortunately this is a known bug in Swift (swiftlang/swift#56165). You can workaround it by changing the call site to:

let bytes: [UInt8] = Array(unsafeData: byteData)!
