QUESTION
I am writing my project and wondered. When I read literature or watch videos, I see that this is bad practice. Why? Is this bad for the system?
What is the difference between this
...ANSWER
Answered 2021-Jun-16 at 00:17You have to initialize all instance properties somehow. And you have to do it right up front, either in the declaration line or in your init method.
But what if you don't actually have the initial value until later, like in viewDidLoad? Then it is silly to supply a real heavyweight value only to replace it later:

QUESTION
In my iOS app "Progression" there is rarely a crash (1 crash in ~1000+ Sessions) I am currently not able to fix. The message is
Progression: protocol witness for TrainingSetSessionManager.update(object:weight:reps:) in conformance TrainingSetSessionDataManager + 40
This crash points me to the following method:
...ANSWER
Answered 2021-Jun-15 at 13:26While editing my initial question to add more context as Jay proposed I think it found the issue.
What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.
My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.
Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.
The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.
QUESTION
How do I produce an animation that simulates the burning effect of fire consuming an UIView from top to bottom in Swift?
I found Fireworks, an app that allows users to tweak and try out different settings of CAEmitterLayer with instant results. The effects are great for applying to a whole screen but how would I use it for my purpose - where the UIView must disappear as the fire consumes it from one end to the other?
Is there some tutorial on consuming UIViews with fire using the particle emitter anywhere? I know that I’m supposed to show some code but anything I put here would be irrelevant. I’ve also exhausted my search engine looking for something similar. That’s how I found the Fireworks app actually.
This seems to be a use case that shouldn't be uncommon.
...ANSWER
Answered 2021-Jun-14 at 14:24I was once in your shoe before and came across this Open source library called particle animations.
I would NOT recommend using the library itself since it's deprecated. But I would recommend referring to its source code to get an idea of how to use CAEmitterLayer and CAEmitterCell to make the looks of a Fire!
As you could see from its readme, it has direct examples of Fire. It also states that even Apple and Facebook uses CAEmitterLayer and CAEmitterCell to produce the effect of a fire.
Feel free to ask for more questions.

Answered 2021-Jun-15 at 08:30Users of external identity providers have to be registered before the can login.
You can find the details here: https://developers.tapkey.io/api/authentication/identity_providers/#working-with-users
When it is necessary for your use case, that these users are automatically created when they login, please send a request to tapkey support and they will enable this feature for you.

...ANSWER
Answered 2021-Jun-14 at 21:52I'm the author of the article you referenced.
As discussed in Discover concurrency in SwiftUI, views can make use of the new .task { } and .refreshable { } modifiers to fetch data asynchronously.
So you now have the following options to call you async code:

Vulnerabilities
Install swift
You can use swift like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
