i want to get the Length of an Array with "sizeof". I tried everything. This is the error message: "[Int32] is not convertible to T.Type"
The Array has to be Int32.
var testArray: [Int32] = [2000,400,5000,400]
var arrayLength = sizeof(testArray)
You can get the number of elements in an array simply with
let count = testArray.count
and the total number of bytes of its elements with
var arrayLength = testArray.count * sizeof(Int32)
sizeof is used with types and
sizeofValue with values, so both
var arrayLength = sizeof([Int32]) var arrayLength = sizeofValue(testArray)
would compile. But that gives you the size of the
struct Array, not the size
of the element storage.
