Is there some way to write/download rules for how VS. Code should format the code?
Example:
I have this nicely formatted (JavaScript) code:
var boundingBox = Object.create(null);
boundingBox.top = 0;
boundingBox.left = 0;
boundingBox.right = window.innerWidth;
boundingBox.bottom = window.innerHeight;
But after I do: Right-click --> Format Document
It destroys it into this (relatively) ugly & "unreadable" mess:
var boundingBox = Object.create(null);
boundingBox.top = 0;
boundingBox.left = 0;
boundingBox.right = window.innerWidth;
boundingBox.bottom = window.innerHeight;
Is there some plugin/.edditorconfig rules/settings/other thing I can do to tell VS. Code how it should format the code? (or at least not destroy the existing formating?)
I think what you want is this extension:
https://marketplace.visualstudio.com/items?itemName=wwm.better-align
It allows you to align your code lines by colon(:), assignment(=,+=,-=,*=,/=) and arrow(=>)
However, my personal opinion is that it would likely be worth it to get used to other code formatting styles. From my experience, aligning code by specific characters is not common practice.

How can I make a check for the correctness of the entered data?
For example, the user needs to enter a digit, and until this is done, the program will not skip it further
In my case, you need to make sure that the user entered an integer, and not a string, double, etc.
Just create an infinite loop. If your read is successful break it. Something like:
while true {
if let line = readLine(), let value = Int(line) {
print("value", value)
break
}
}

Im trying to check if an hour is below 10 so i can add a 0 behind it to make it the right hour format.
All my efforts till now haven't worked out.
Thank you for you time
You can use padLeft() method on strings. It takes width and padding parameters. You can use it like this:
print("5".padLeft(2,"0")); // Prints 05
print("14".padLeft(2,"0")); // Prints 14
you can try this;
var now = new DateTime.now();
String newHour = now.hour.toString();
if (newHour.length > 2) {
newHour = "0"+ newHour;
}

I have a problem with youtube duration.
How to separate this string:
PT1H50M20S
to 1:50:20 with NSRegularExpression.
No need to use NSRegularExpression here, you can use NSCharacterSet instead.
let s = "PT1H50M20S"
s.componentsSeparatedByCharactersInSet(NSCharacterSet.letterCharacterSet())
.filter { $0 != "" }
.joinWithSeparator(":") // 1:50:20

How could I write this in real code?
if (!UIImageView with origin.x > 50.0) {
//Exlcude the imageview from whatever happens in this statement.
}
if (imageView.frame.origin.x <= 50.0) {
// The code in this block won't bother the image views
// with 'x > 50.0' anymore
}
