18,813 PointsHi, Wilztan. My Swift is a little rusty, but I believe this is trying to be a generic function definition. However, I believe it should be:
func DisplayArray<SomeType>(array:[SomeType]){ //code here } - That would mean it is a function that takes an array argument, but the array can be of any type. The type is later specified in the function call like this - DisplayArray<Int>(someArrayWithInts). (The //code here part is where the actual code for the function would go - presumably to display the array...)
OR
func DisplayArray(array:[Int]){ //code here } - This would be the same function, but it would only work with an int array as the argument.
Hope that helps!

Python Web Development Techdegree Student 4,979 Pointsnot that, the way you say i understand but look at this code
func DisplayArray<SomeType>(array:[Int]){
}
DisplayArray<SomeType> mean what?
