I wanted to try out the swift language today but did not find any clear instructions on how to install it on linux for fedora, which uses redhat. Anyone know how to do this?

I just bout a 2020 M1 512gb SSD 8gb ram for $600 to learn swift with.

Will this machine be good enough to both learn what I need to learn for app making and also carry over into actually making the app?

I started my career in iOS. I later moved to macOS apps & tvOS apps. Started with objective C and moved to Swift.

In 2015 - I started my dev agency specializing on native iOS apps. I attended WWDC and running a apple developers community online.

Slowly we have grown to full-stack agency with web, native apps & cross-platform apps.

We are 12 native developers iOS and android. We are mainly maintaining old apps and building very few new apps.

Lately, we are seeing cross-platform apps are in more demand from clients perspective. We are not seeing this trend reversing. Are you?

Looking forward to learn your views.

Edit: we are grown to 70 people team. Focusing on niche like fintech, sports, fitness, legal etc.

I'm using a bit of example code from Apple

    func random() -> CIImage {
       let randomGenerator = CIFilter.randomGenerator()
       return randomGenerator.outputImage!
    }

but I get an error that CIFilter.randomGenerator() doesn't exist

what do I have to import to use CIfilters. I'm already importing CoreImage

Hi everyone!

I have been working with weather kit recently. I fairly new to Swift and am having trouble figuring out how to get the wind speed from Weather kit. I know it might sound a little silly asking about the wind speed specifically, but a lot of the other features such as the temperature are shown in the tutorials that I have looked at but for some reason I haven't seen one that included wind speed. I would really appreciate it if someone could please show me how to display it on the screen.

Thank you!

So I started to teach myself how to code using Swift Playgrounds and I was wondering if I should skip Get Started with Code and go straight to Learn to Code 1? I've heard people say that Get Started with Code is incomplete and doesn't really explain how to do things.

Hey Everyone, just released my first Swift app and would love for you guys to check it out and give some feedback! It's a simple tourism app I made for my state that lists some towns, state parks, and restaurants, and also events that are happening (still in the process of adding more data). I hope to add some features that actually differentiate it from just using google/apps like yelp or trip advisor, but it was still a great way to learn IOS Development. Thanks!

I’m the only one working on my basic project (no one else is pushing changes!), yet I still get merge conflicts. When I try to resolve the conflict, it says the conflicting file doesn’t exist in my local repository. At this point I need to re clone the repo only for this to eventually happen again… does anyone else get these weird issues? I’m reasonably familiar with git/github and have used it for years without issues, but the Xcode version seems like a horrendous buggy mess. Back to the command line I guess.

Almost exactly a month ago, I released SwiftyLaunch. It’s an iOS App generator that allows you to select all the functionality that you might need in your next iOS App and it would generate an iOS Starter Project with these things already configured for you.

Things like the complete Auth Flow, In-App Purchases, Push Notifications, Setup & Connection with Backend and DB, and more. You just select all the "tedious" things to setup and we do it for you automagically (sorry for the cheesiness). This way you can focus on what makes your App unique, and not on setting up the Sign-In Flow again for the 10th app in a row!

The launch was as great as it was a disaster. Every couple of hours I'd have a crisis to fix. Some of my favorite ones:

• Support/Contact emails not even working for the first 3 days
• App Generation failing on over 50% of users devices
• Users were able to circumvent my license screen by simply pressing ESC (it was a sheet, and I didn’t know that on Mac it was automatically dismissible without explicitly stating .interactiveDismissDisabled()!!

But now, just a month down the road, SwiftyLaunch was already used to launch 6 (!) iOS Apps on the App Store. These Apps have already generated cumulatively just over $4,500 in revenue. It’s insane!

Reddit was the first place I promoted SwiftyLaunch and got my initial purchases. This is also the place where I always found interesting post and articles that helped me become a better Developer and where I made some very good iOS Dev-friends! Thanks so much for being such an amazing community.

Now, to the interesting part: You guys are incredible. You build insane things that people use and love every day. I want to give back. This is why I am going to give away 3 SwiftyLaunch Ultra (worth $199 with the Launch Discount) to the three most upvoted comments idea saying what you’re going to build with this. And better yet, build it in public and share your experiences and struggles, your victories and defeats.

In simple words: Write your next iOS App idea. 3 most upvoted comments will receive a free SwiftyLaunch Ultra license to build this idea. Winners will be selected in exactly one week, on April 13th.

Enjoy!

Is there really a noticeable difference in speed when developing iOS apps/games in Swift?

Isn't the M3 MacBook Pro a better value?

Do you let the newest version of Xcode to do it or do you update the swift code manually?

I want to start learning iOS programming. I have some basic knowledge of Python and C++. Do any of you have any recommendations on how to learn Swift?

Congrats to all the winners this year! It’s my first time winning and was curious to know how long it usually takes for Apple to send the student swift challenge winner awards/gifts? Living in Canada 🇨🇦

Hey Guys,

I want to store my app's users' data into separate sqllight files, hence if a user logs out and logs in with a new email, I want his own data being loaded, I tried changing ModelContainer but it does not sound effective (perhaps because the context in different views still having old data?). What is the right way to handle the switch?

All students probably know Quizlet and other vocab trainers and how they charge 7$ per month. I just published my first app on the Apple AppStore. It's called TurboTerms and it charges 99ct or 1.99$ ONE TIME depending on your region. After that you never have to pay again and you receive constant updates. If you're interested, heres the link:

Hi guys,

retrieveTransactionsFromKeyChain(completion:) wither crashes or returns nil.

If keychainDictionary contains kSecMatchLimit: kSecMatchLimitAll it returns nil.

If keychainDictionary contains kSecMatchLimit: kSecMatchLimitOne it crashes.

What am I not getting about this?

Here is my code:

private func saveTransactionToKeyChain() {
        keychainQueue.async { [weak self] in
            guard let self else { return }
            if let tempTransactionID {
                retrieveTransactionsFromKeyChain { retrievedTransactionArray in
                    var transactionArray: Set<UInt64> = []
                    if let retrievedTransactionArray {
                        // If it exists, append to it and save...
                        transactionArray = retrievedTransactionArray
                        transactionArray.insert(tempTransactionID)
                    } else {
                        // If it doesn't exist, create it and save...
                        transactionArray.insert(tempTransactionID)
                    }
                    
                    let data = withUnsafeBytes(of: transactionArray, { Data($0) })

I used the search bar for this question but most posts were old, so here’s my question :Can you deploy apps to the iPad and iPhone app stores using Swift Playgrounds on a Mac?

I can not decide which one to choose. I am a flutter, and backend developer and started to learn swift. Which one of these is better if they have the exact same price, ram and storage.

I'm trying to have users print fiducial markers from my Swift application with fixed sizes and known dimensions for a Computer Vision application. It seems nearly impossible to somehow setup the iOS print job such that the PDF doesn't get scaled in some way.

I would rather not have users have to export to another device where they would then have to manually set up the print job to ensure that no scaling occurs. Any advice on how to accomplish this? I've tried messing with the UIPrintPageRenderer
but the documentation on this is lacking and it generally just behaves extremely cryptically, scaling and stretching in unpredictable behaviors.

I've also made sure that the PDF is formatted for US Letter and that there is no content within an inch of the edges of the paper.

hello guys! just want to ask if where can I able to see latest basic swiftui tutorials? on youtube I can see they are a little outdated. pls help.

I would love to have a feature that automatically generates documentation for functions / classes that is native to XCode. I could just copy all my code into chat gpt, but I feel like it’ll take too much work. Is there any plan of this happening? Or is this just pure optimism on my end?

I am coding a meditation kind app and I’ll play no-copyright relaxing musics. There will be 22 mp3 files(5 min each.) Is it logical to use assets folder directly or should I try to fetch them from internet? I don’t want to increase the size of app itself.

I'm building a video player for a react native applications. There are 3 pieces of info I want to shuttle from the swift side to the react native side.

• current time
• whether the video has reached the end (ie not paused)
• if the video is currently playing

I've figured out how to add an observer to the player that sets the current time of the video so what I'm trying to figure out now is how to "listen" for the play/pause/end events. Not necessarily even just the tap of the play button but if the video also stalled from a poor connection.

So basically I'm trying to figure out how to listen for the current status of the video playing.

Here is the code I've written so far:

import Foundation
import AVFoundation
import AVKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        var blackSquare: UIView
        blackSquare = {
            let black = UIView()
            black.translatesAutoresizingMaskIntoConstraints = false
            return black
        }()
        let BCPlayer = StreamingVideoPlayer()
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        blackSquare.backgroundColor = .red
        view.addSubview(blackSquare)
        addConstraints()
        
        let m3u8: URL = URL(string: "https://demo.unified-streaming.com/k8s/features/stable/video/tears-of-steel/tears-of-steel.mp4/.m3u8")!
        BCPlayer.add(to: blackSquare)
        BCPlayer.play(url: m3u8)
        
        func addConstraints() {
            var constraints = [NSLayoutConstraint]()
            constraints.append(blackSquare.leadingAnchor.constraint(equalTo: view.leadingAnchor))
            constraints.append(blackSquare.trailingAnchor.constraint(equalTo: view.trailingAnchor))
            constraints.append(blackSquare.bottomAnchor.constraint(equalTo: view.bottomAnchor))
            constraints.append(blackSquare.topAnchor.constraint(equalTo: view.topAnchor))
            NSLayoutConstraint.activate(constraints)

Hello, my first post here and I'm sorry if the question is as stupid as it seems but it's still my question.

Is it possible for me to program using Swift and SwiftUI, obviously with a plugin, in VS Code on Windows?

I understand that I won't be able to compile the application and therefore I thought about using MacInCloud, I understand that this is a "hack" but it's because I live in a 3rd world country and the MacBook here is very expensive, I'm struggling to be able to buy one , in the meantime I would like to know if a "hack" like this would work.

Thank you kindly for every response.

Looking for anyone who has

1. released an app in the current year and had repeated app store submission issues out of thin air
2. or has had a submission wait in review for over a week

I released an app last year. For months I was able to send updates and get approved with fairly little friction. Mar 12, 2024 I submitted a build that got rejected. I made subsequent fixes and submissions that were rejected again the following day, twice on the 14th, and the 16th. Most of all the rejections were inaccurate metadata and minimum functionality. Which is odd because the app has existed virtually the same way since last year, when getting approved was not a problem. The only difference as of recent is we've had a tiktok go viral and led the app to start charting.

On the 17th I made a submission that fulfilled all requirements. I was marked "In Review" from the 17th to the 23rd. Yes a full week. I canceled my submission on the 7th day and resubmitted with a change I thought they'd potentially look for. It has been "Waiting for Review" since then. Going on 14 days.

I contact support every 3 days however they've only responded once, saying they are "proceeding with an expedited review" however it's never shifted to in review.

I'm a frontend web developer who is trying to get into Swift and iOS in general. I'm currently trying to make a tictactoe game with UIKit. I used storyboard to place a bunch of buttons that I plan on using to trigger a placement.

However, my plan was to make the buttons blank, but upon press either place an 'X' or a 'O' depending on who's turn it is.

Now my issue is, how do I do the equivalent of 'data-attributes' or 'value' in html in swift?

I've read the documentation (skimmed, admittedly) and tried searching. But as far as I've read I can pass tags (which are integers only) and the title and styling of the button to a function.

Basically I want the upper left button to have the value of '0,0', but button next to that '0,1' and I want to pass these values to a function.

I'm at a loss atm

I am coding my own app for app store. I don’t use any libraries except revenuecat. And app memory usage is 1.25 gb at launch. Sometimes even it can crash. What should I pay attention for better usage? Is 1,25 a lot?

Any recommendation?
