Problem with 1D + operator

[MUECKE446]

    let A = [1.0,2.0,3.0]
    let B = [4.0,5.0,6.0]
    let C = A + B   <-------- error: Ambiguous use of operator '+'
    print(C)
    var D : ValueArray<Double> = [1.0,2.0,3.0]
    var E : ValueArray<Double> = [4.0,5.0,6.0]
    let F = D + E   <-------- this works ok
    print(F)

I have no idea how can I fix it: for a build in Double array + for appending exists.
Can someone help?

Yes, for Array + is defined as concatenation. You have to use ValueArray. You can also write as:

var D = ValueArray([1.0,2.0,3.0])
var E = ValueArray([4.0,5.0,6.0])
let F = D + E

Hello Alejandro, this is evident, but I mean, that than the public func for + in the package should be removed. Von: Alejandro Isaza [mailto:notifications@github.com] Gesendet: Dienstag, 21.

There are two options if you want to concatenate:

1. Use A.append(contentsOf: B)
2. Do this in a Swift file that does not import Upsurge
