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?

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.

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.

If you grossed over $20,000 (or 200 sales) in sales from Apple you will receive a 1099-K.There are 2 problems with this:1) This will NOT reflect the 30% that Apple has withheld.2) A 1099-K will only be sent for those regions that meet the criteria for Apple issuing a 1099-K. Thus, this won't reflect all of your sales. Note: this is an assumption as I had more sales then this 1099-K reflects. In my case, I only received a 1099-K for US sales (I assume as it doesn't say). As a result, the difference from what the 1099k is reporting and what I actually received is only 12%, not 30%. That is, for example, the 1099-K says that I had$20,000 in sales, but what was actually deposited in my account was $17,600.How did you guys/gals fortunate/unfortunate enough to receive a 1099-K report this on your taxes?Did you, for example, have:a) 1099-K income of $20,000 with a business expense of 30% = $14,000b) Addional non-reported income of ($17,600-$14,000) = $3600Total: $17,600 (amount actually received from Apple sales)-OR-a) 1099-K income of $20,000 with a business expense of 12% = $17,600Thanks for the help with this!

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.

Hello, I've been attempting to generate this code, but the last line returns an Expected declaration Error.

When I go to my terminal and type in "python" or "python --version" I get back "command not found: python"
I have the newest version downloaded but not even version 2 isn't showing up. What do I do?
I even just factory reset my mac. I'm running the M1 mini
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

As you prepare your students for a future driven by technology, teaching them how to code is critical. It opens new doors to potential careers and helps prepare them for college. Starting this school year students can earn App Development with Swift certification through Certiport based on the free App Development with Swift course from Apple. Level 1 certification recognizes knowledge of the Swift programming language, app developer tools, and core components of apps, and can be offered by any Certiport Authorized Testing Center that has purchased access to it.* Students who pass the exam will earn a digital badge to showcase their achievement on a resume, portfolio, email signature, or career networking site.Learn more about App Development with Swift certification at Certiport.com >*Additional terms may apply; see the Certiport website for more information.

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...

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.
