So the issue I'm having is that I have an object with a argument in the init() that requires an [UInt8]. I want to be able to grab a range from another array and use that in the init. See example.
class Test {
init(fromArray: [UInt8]) {
// performs work
}
}
let myStockArray: [UInt8] = [1,2,3,4,5,6,7,8] // reference array
let test = Test(fromArray: myStockArray[1...4]) // doesn't work
How can I get this to work? The error I get is: Cannot subscript a value of type '[UInt8]' with an index of type 'CountableClosedRange'
Subscripting an array with a range doesn't return an array and this is the main issue. You are trying to setArraySlice<UInt8>
type data to the constructor that have inside [UInt8]
type.
Try this approach:
class Test {
init(fromArray: [UInt8]) {
// performs work
}
}
let myStockArray: [UInt8] = [1,2,3,4,5,6,7,8] // reference array
let test = Test(fromArray: Array(myStockArray[1...4]))
