这是我用于测试从数据表示形式获取浮点数数组的代码:

this is the code I used for testing getting an array of floats from Data representation :

    let arr: [Float] = [32.0, 4.0, 1.2]
    let data = Data(buffer: UnsafeBufferPointer(start: arr, count: arr.count))
    print("---> data: \(data)")

    var myFloatArray = Array<Float>(repeating: 0, count: data.count/MemoryLayout<Float>.stride)
    myFloatArray.withUnsafeMutableBytes { data.copyBytes(to: $0) }

    print("---> myFloatArray: \(myFloatArray)")
