Reply to Problem with matching arrays and indexes
I apologize, it is confusing. I don't know what to do so there is no code yet. My previous attempts are snippets and are not whole. I'm looking if there is a function to do this process below before I start coding again.The values are values of the variables x and y, in this specific case the values are 3 and 5, however, the values of x and y will change every loop.As well as the fact if we convert the numbers into strings it would be pointless again, because it would be searching for x, and not searching for the actual value of x.What I was trying to say here is simply I tried the function arrayValue.containsand in order to do that .contains function, I would need to string x, which would make the .contains function search for x, instead of the actual value of x, in this example is 3.if arrayValue.contains(x){}Sorry if it's not clear, I'll do my best, since I am confused myself.

Reply to guard vs control-flow-aware typing?
It is in effect the same thing. In particular, you can currently write this code (where x is a property of optional type):guard let x = x else {return} // 'x' is an unwrapped local for the rest of the scopeNote that it's not really unsafe, because you can't assign to the new 'x', and it has the same value as the old x.All that's really in question here is whether this sort of thing is always going to require an explict let x = x somewhere in the syntax, as above, or whether this in the future might be done silently by the compiler.

Reply to Converting meters to millimeters
I was told the code below was the correct code to use to convert a 3d scan in meters to millimeters. I must not have it in the correct place in the code in my first post. vertex[j].x = vertex[j].x * 1000.0; vertex[j].y = vertex[j].y * 1000.0; vertex[j].z = vertex[j].z * 1000.0;
