问题 I've been trying to figure out how to take next available day based on Present day i.e., if today is Friday, then search in Array for the next nearest day like if Array values are 1[Monday], 2[Tuesday], 4[Thursday], 6[Saturday] then my next day should be Saturday. Here is what i tried //Here i'll get days like 0, 2, 3, 4, 6 pattern, and i'm spliting them based on comma to get single-single day value in array of string string[] GetDays = DayInWeek.Split(','); [Here day patterns will change

问题 I am trying to loop through an array in SwuftUI to render multiple text strings in different locations. Going through the array manually works, but using forEach-loop produces an error. In the code sample below, I have commented out the manual approach (which works). This kind of approach worked in this tutorial for drawing lines (https://developer.apple.com/tutorials/swiftui/drawing-paths-and-shapes) (As a bonus question: is there a way to get the index/key of the individual positions

Tom Hardy Brad Pitt I use this, to take the names from the file and split them. $Names = gc C:\Temp\Name.txt ForEach-Object {-Split $Names} How do I then assign each first name to $FirstName and each last name to $LastName? The idea behind this is that further down the line, for each $FirstName I will be creating a specific individual item with each name. I understand that after I run the above, each section of the name is
