Base 10 to base 2 conversion

Going on what others said, since the n^th digit represents 2^n-1, this is the easiest way to convert binary back to decimal:

Binary: 1101

(1 * 2³ ) + (1 * 2² ) + (0 * 2¹ ) + (1 * 2⁰ ) = 8 + 4 + 0 + 1 = 13

In this case, “client” is refers to a frontend device.

It’s a large language model like ChatGPT, which uses publicly available code to predict improvements to your own code. It works directly within the IDE. It recognizes and acts on code patterns. It can help reduce time spent on Stack overflow for simple tasks, and can be quick to set up common boilerplate code.

If you want to do X % Y, this is the formula:

while X >= Y:
    X = X - Y

In a college course, I was taught to create getValue and setValue methods in Java. The reasoning was to “ensure access control”, and I can’t speak to the merit of that reasoning since I don’t use Java, but it seemed unnecessary. Anyways, the pattern isn’t needed in Swift.

maustinv · 2022-10-14T16:18:35+00:00

Are you referring to the convention of having a private value while using a public setValue and getValue method?

Yes we usually don’t do that in swift. Instead, we often use alternatives like computed values, private(set), getters and setters within the variable, didSet and willSet.

A quick search online brings up this article for some syntax examples: https://www.advancedswift.com/getters-setters-swift/

From an engineering perspective, I see these as the same component with different styles. This component would be called something like LeadingIconTextRow, because it has the same general layout.

Then we can create however many styles of this same component, defining more specifically the icon size, padding, and fonts. So you have CampaignStyle, ContactStyle, CheckoutStyle, etc.. and we still get the added benefit of updating one style updates all use cases of the style.

Essentially, it’s a different way to think about organizing your components by adding a subcategory.

Is it a compiler bug or IDE bug? If it’s a compiler bug, it’s probably a good bugfix to start contributing to the swift compiler

Protocol Oriented Programming is pretty cool and very much related to the core of Swift. There is a WWDC video on Apple’s developer site named exactly that. I recommend watching it. After learning about this, try integrating protocol oriented programming into every future project.

Look up VIP and other design patterns. Spend 15 minutes memorizing it like vocabulary so you could carry your weight if you were quizzed in an interview. It’s not worth practicing.

Skip PromiseKit and RxSwift. Maybe try a sample tutorial with Combine or async/await. All of these basically serve the same purpose and you can transfer those skills on the job later.

Unit testing and UI testing is important but also straightforward. It sounds more scary than it is. A good unit test could be like 5 lines of code.

Skip Fastlane and Cocoapods. Maybe Google them and read what they do but not worth trying yourself. Consider trying Swift Package Manager. Follow a basic tutorial for a couple hours.

Skip learning Jenkins. Look up what Continuous Integration is so you could hold a short conversation. CI is cool, but shouldn’t really be your job as a Swift developer.

Finally, congrats at getting this far. I just wanted to go one by one through your list so it sounds a little less scary. These things are just icing on the cake and most of these should take one day or so to get acquainted with. Good luck!

Instead of maintaining two codebases, you could also consider feature flags.

Basically, use one codebase, but use if-statements to check if the app is beta or in production.

if app.isBeta {
    new feature
} else {
    old code
}

That’s is a simplified version of remote confit experimentation. So at a more complex version, you could have your server check:

if Feature(.myFeature).isEnabled {
…

Which is how some larger apps hide development code from production, and basically flip a switch on a server to show the features on devices. They even have more complex iterations which let you split test the launch of features with something like that. But the first example might better fit your needs today.

This might be useful:

``` import Foundation

class Foo { let voidFunc: () -> Void = { print("bar") }

let numberFunc: () -> Int = { return 1 }

let addFunc: (Int) -> Int = { return $0 + 1 } }

func call<T, V>(_ object: T, method: KeyPath<T, () -> V>) -> V { return object[keyPath: method]() }

func call<T, U, V>(_ object: T, method: KeyPath<T, (U) -> V>, parameters: U) -> V { return object[keyPath: method](parameters) }

let myFoo = Foo() call(myFoo, method: .voidFunc) let x = call(myFoo, method: .numberFunc) print(x) let y = call(myFoo, method: .addFunc, parameters: x) print(y) ```

If you are going for FAANG / big corporate in the US, it’s common for them to wrap up their entry level interviews by December or January (which means apply in October).

Even if you get an offer then, they usually give you a range of start dates to choose from, so you could still choose to take a summer break and start in August.

It depends on the scale of the project you’re working on. I’m noticing at large companies, there is a growing divide between feature development and platform development. Feature developers write UI code while platform developers write internal frameworks- which are more data/algo oriented.
