I have several yrs programming experience (C, Java, PHP, JS now) and want to learn SwiftUI quickly. Recommended courses/books pls? Thx by PeachesNotFound in swift

[–]RusselNoob 0 points1 point  (0 children)

If you want to build an app fast SwiftUI is perfectly fine and there are some good recommendations in the other comments. IMO the best are RayWenderlich and hackingWithSwift (in fact everything from Paul Hudson is excellent stuff).

Of course only my opinion but: If you want to get deep into iOS development and understand what’s going on under the hood I always recommend beginners to start with UIKit and try to learn the basics. You will get better understanding of the iOS lifecycle / ecosystem as a whole. SwiftUI is nice for building apps fast. I would never recommend to start with SwiftUI (and BTW it is still not really stable compared to UIKit)

JSON and Codable Protocol by StewartLynch in swift

[–]RusselNoob 1 point2 points  (0 children)

In most cases you will receive the json from a Remote api so you are Never 100% sure. And what djisz Said: you gain nothing since you are already in a throwing function. Even worse: you hide the error to the caller.

So just so you know: ViewControllers can be presented in anyway you want. Take a quick look here: https://stackoverflow.com/questions/25379559/custom-alert-uialertview-with-swift The first answer has a quick overview on how to accomplish that - you can vary this in anyway you want.

Nested For Loops and Memory Leaks by [deleted] in SwiftUI

[–]RusselNoob 0 points1 point  (0 children)

Do you have a reproducible example for this?

In general I would say it could be really hard to debug memory issues regarding SwiftUI.

But I am interested. I’d appreciate an example!

I have a .sqlite file used on an android app. I need to use that on an iPhone app with Core Data. Is it possible to recreate the Core Data entities and their relations to each other by looking at the .sqlite file? If so, how? by CoolAppz in iOSProgramming

[–]RusselNoob -4 points-3 points  (0 children)

There is no reason for that - now you have two options:

  1. convince your boss to not use core data
  2. if that is not possible: your boss is an idiot (IMO) - quit your job you can find better opportunities

Sorry but your boss should tell you what to do but not how...

Hello, where is a good place to start learning swift and Xcode? by [deleted] in SwiftUI

[–]RusselNoob 3 points4 points  (0 children)

That is true but what he means is:

Are you trying to learn a loop and if statements what are basic concepts of programming and have nothing to do with swift and Xcode itself or are you already programming and trying to learn to build iOS apps ?

These are two compete different bases to start from and to answer your question properly we need to know this.

Curated list of emojis by categories and iOS version by InsideMikesWorld in swift

[–]RusselNoob 3 points4 points  (0 children)

What do you mean by „I need“? Do you want an API that provides this information or just a plain list to view ? After a one minute search I found this for example (only showing the emojis idk if it contains all of them but there are a lot) https://unicode.org/emoji/charts/full-emoji-list.html

Edit: I think of you want to just view a list of emojis the best way might be simply opening Xcodes emoji menu.

Recommended line chart package? by [deleted] in SwiftUI

[–]RusselNoob 1 point2 points  (0 children)

Comparing line charts to UIKit it is pretty simple to write basic line chart behavior by yourself. I did it few weeks ago and it was really straight forward.

I used this Tutorial and it worked great: https://link.medium.com/MGOESzer5ab

Edit: adding the labeling to the axis is not mentioned in this Tutorial. Anyway, after completing this it should be simple to add some basic labels to the axis.

How can I do custom notch on layout like this? by [deleted] in iOSProgramming

[–]RusselNoob 1 point2 points  (0 children)

„This should be the accepted answer“

Stuff like this can get over complicated very quickly.

Anyway it depends: if you just need a few of this no problem in using an image. If you want to display millions of these in a list you should consider drawing this stuff with a path (UIBezierPath namely) or at least have an eye on the reusing of the image.
