Hi friends. I'm new around here and just migrated from Windows to macOS. I started working on iOS development with Swift. So if you have any study resource suggestions for beginners, can you share them? I am open to all resources such as documents, websites, videos.

This is the content view which moves down on the screen as I open it from different view.
when I click top left button to open menu.
The menu
When I click the Home option from menu whole view moves down on screen.
The whole view gets moved down on screen each time I open it.

Something wrong with Readline. I can't use
readLine()!)!
My code is really simple:
var aYear = Int(readLine()!)!
func isLeap(year: Int) {
var leap = "NO"
//IF divisible by 4 with no remainders.
if year % 4 == 0 {
leap = "YES"
//Is leap year, unless:
}
if year % 100 == 0 {
leap = "NO"
//Is not leap year, unless:
}
if year % 400 == 0 {
leap = "YES"
//Is leap year.
}
print(leap)
}
//Don't change this
isLeap(year: aYear)
This error keeps coming up. I can't figure out how to fix this error:
"__lldb_expr_122/readline .playground:1: Fatal error: Unexpectedly found nil while unwrapping an Optional value
Playground execution failed:
error: Execution was interrupted, reason: EXC_BREAKPOINT (code=1, subcode=0x18f494588).
The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation."
It is really strange because in online compiler this simple code works just fine.
PLEASE HELP ME. I CAN'T FIND THE SOLUTION.
It's kinda internal xcode error or what...
Hello all,
I was wondering in the Swift Student Challenge requirements, it states: All content should be in English. What if my game is mainly in English (UI, main content,) but some foreign language (glyph to be specific) is used as part of app. The judge should be able to use the app without any fluency other than English. Will including some foreign language disqualify my entry?
Thank you so much for answering my question.
Nico

Hi, does anyone know how to access buttons through a different view controller in Xcode? For example, in firstViewController I placed a button that is disabled, but once the user presses the button in the secondViewController, the button in firstViewController becomes enabled.

Is there a logical disjunction operator or function in Swift?
Even better, is there a logical disjunction that works with optional variables instead of boolean variables that returns an object when true, and returns nil when false?
A logical disjunction evaluates two boolean variables, and if at least one of them is true, then the return value is true. If neither variables is true, then the return value is false.

I'm looking for the Swift tutorial that had always been used since I started learning Swift for the first time about 5 years ago. I can't remember the name. It was an app that reviewed restaurants, as I remember. I need a sample of key-value-coding. I recall that tutorial used key-value-coding.

Apple has a "Develop in Swift" curriculum with three books available at
https://developer.apple.com/learn/curriculum/. However, they link to Apple Books, which isn't available in China. Is there any possible way to download an English copy of it without going through Books? Thanks!

I created a swiftpm project with Xcode Version 13.4.1 (13F100).
I changed the target from the default created by Xcode to this:
targets: [
.executableTarget(
name: "App",
path: "App"
)
]
I also changed the package version to 5.6 to match the AboutMe Package file.
I also created an App directory and moved all my files (bar the Package.swift file) to it, and I also created a Guide folder and created a Guide.tutorial file based on the example in the WWDC video.
I've turned on Author Debugging Mode (this is on Swift Playgrounds on the Mac, I'll try later on Swift Playgrounds on the iPad), but I get no messages other than the "Could not display guide. Try reopening the current project..."
I also get a build error that just says "Building failed"
What am I missing?
