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

This crash points me to the following method:...

While 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.
In a singleton class I am trying the following code with 3 URLs stored in a dictionary:...
ANSWERAnswered 2021-Jun-13 at 10:59
urls is actually of type
[String: URL?]. Note that the value type is optional, because
URL.init(string:) is failable.
When you try to get a value from this dictionary, you get a
guard only unwraps one layer of the optional.
One way to unwrap a nested optional (no matter how many layers), is to use

I am programming a basic fps app on Xcode using Swift. The error comes in my Bitmap.swift file, which is meant to store pixels in a 2D array so that there's a way to represent an entire image in the app.

I am trying to build a iOS application that has a side menu. And my intention is when I click on a item in the menu the new view will appear on screen like the 'HomeViewController' and for each consequent item like example1, 2 etc (In place of the menu button, Note I will be adding the top nav bar soon to open the menu) I am wondering how I can accomplish this feature?
ANSWERAnswered 2021-Jun-10 at 23:33
You'll need a couple of ingredients:
- A way to store the state of the currently active view
- A way to communicate the state between your menu and main content view
For the first one, I made an enum that listed the different types of views (
ViewType) and added it to your
For the second, you can pass state via a
@Binding from parent to child views and back up the chain.
I'm making a request to my server with AlamoFire, and I have a setup something like this, where "self.error" is a String variable....

You can try
err.localizedDescription or you can get the error in the completion of the function and return it
I am trying to use Combine to route SwiftUI views, and it sort of works, but has some unwanted behaviour that I hope someone can help me with. I made an example project which only contains two files,

ViewRouter is a
ViewModel for the SwiftUI Views that contains a
@ViewBuilder property. When the
SwiftUI views calls the
didFinish() function, the
step property is set to the next
ANSWERAnswered 2021-Jun-06 at 08:16
I have made some small changes to the ViewRouter class to make this work. I came to the conclusion that all SwiftUI views need their own ViewRouter instance. Using the same shared instance of ViewRouter for all views results in the unwanted behaviour. I have introduced a
nextStep optional property that is set to the current step when a view calls the
didFinish function, to make sure that the router returns correct
nextStepView if called a second or third etc times.
I have pushed an update to the GitHub repo for the example Xcode project.
The modified class now looks like this:

You haven't mentioned anything about how you are testing network extension. You should attach a Network extension process before running your project for debugging. Then only network extension methods will trigger for debug.
DetailCollectionViewCell includes a WKWebView that loads specific video and text embedded from the server. My goal is when the user clicks the back button, the video should be stopped. I've tried reloading or setting WebView's URL to nil, but I get Fatal Error and nil value for Web View every time I try to effect detailWebView....
ANSWERAnswered 2021-May-31 at 06:43
I've used this method to achieve my goal.
Basically what it does is, disables in-line playback and only allows tvPlayer to play on full-screen thus when the user closes full-screen, the video stops.
