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
I successfully created a timer for when buttons are clicked. When the first button is clicked, the time intervals are exactly at one second. But the moment I pressed another button that is paired with the same IBAction function, the time intervals get shorter. Essentially, after every button pressed, the time intervals get shorter and shorter.
Why is this occurring and how can I solve this?
...ANSWER
Answered 2021-Jun-14 at 19:43Because every time you tap the button, you create another timer.

I know how to preserve the action we have done on UITableView
, after scrolling back and forth.
Now Iam doing a simple UITableView

QUESTION
I have created a "lock" in Swift and an Atomic property wrapper that uses that lock, for my Swift classes as Swift lacks ObjC's atomic
property attribute.
When I run my tests with thread sanitizer enabled, It always captures a data race on a property that uses my Atomic property wrapper.
The only thing that worked was changing the declaration of the property wrapper to be a class instead of a struct and the main question here is: why it works!
I have added print
s at the property wrapper and lock init
s to track the number of objects created, it was the same with struct/class, tried reproducing the issue in another project, didn't work too. But I will add the files the resembles the problem and let me know any guesses of why it works.

I think this is those lines that really explains it 💡
In Swift's formal memory access model, methods on a value types are considered to access the entire value, and so calling the wrappedValue getter formally reads the entire stored wrapper, while calling the setter of wrappedValue formally modifies the entire stored wrapper.
The wrapper's value will be loaded before the call to
wrappedValue.getter
and written back after the call towrappedValue.setter
. Therefore, synchronization within the wrapper cannot provide atomic access to its own value.

QUESTION
I want emacs to autocomplete std functions such as push_back of vector
...ANSWER
Answered 2021-Jun-11 at 17:50Assuming you've installed the irony-mode-server, try M-xirony-cdb-menu
. If that shows no compilation database, there are a few options to tell irony where to look for includes (discussed in the documentation). Irony will provide completion based on sources found in the compilation database.
Of those options, I use a .clang_complete file in my project directory. To complete for vector in your example, assuming you are using g++ version 9 (replace the '9' with your major version), the following simple .clang_complete file may be sufficient (add -I entries for additional include paths as necessary)
.clang_complete

I want to build my Xcode project (react native & swift) for the simulator and on a real device.
The simulator worked great. Today I tried to build it for my device, I selected my device in the Xcode bar and added the scheme to release (I had to do this because I'm using react native and otherwise the bundle is not packed)
Then an error during the build occurs (in this case for the dependency RNPurchases, but this is completely random. sometimes it's Expo-Keep-Awake or Facebook)
