QUESTION
This question is about two MAUI controls (Switch and ListView) - I'm asking about them both in the same question as I'm expecting the root cause of the problem to be the same for both controls. It's entirely possible that they're different problems that just share some common symptoms though. (CollectionView has similar issues, but other confounding factors that make it trickier to demonstrate.)
I'm using 2-way data binding in my MAUI app: changes to the data can either come directly from the user, or from a background polling task that checks whether the canonical data has been changed elsewhere. The problem I'm facing is that changes to the view model are not visually propagated to the Switch.IsToggled and ListView.SelectedItem properties, even though the controls do raise events showing that they've "noticed" the property changes. Other controls (e.g. Label and Checkbox) are visually updated, indicating that the view model notification is working fine and the UI itself is generally healthy.
Build environment: Visual Studio 2022 17.2.0 preview 2.1
App environment: Android, either emulator "Pixel 5 - API 30" or a real Pixel 6
The sample code is all below, but the fundamental question is whether this a bug somewhere in my code (do I need to "tell" the controls to update themselves for some reason?) or possibly a bug in MAUI (in which case I should presumably report it)?
Sample codeThe sample code below can be added directly a "File new project" MAUI app (with a name of "MauiPlayground" to use the same namespaces), or it's all available from my demo code repo. Each example is independent of the other - you can try just one. (Then update App.cs to set MainPage to the right example.)
Both examples have a very simple situation: a control with two-way binding to a view-model, and a button that updates the view-model property (to simulate "the data has been modified elsewhere" in the real app). In both cases, the control remains unchanged visually.
Note that I've specified {Binding ..., Mode=TwoWay} in both cases, even though that's the default for those properties, just to be super-clear that that isn't the problem.
The ViewModelBase code is shared by both examples, and is simply a convenient way of raising INotifyPropertyChanged.PropertyChanged without any extra dependencies:
ViewModelBase.cs:

This bug was recently posted and there is already a fix for the Switch to address this issue.

I tried upgrading Android Gradle Plugin from 4.2.2 to 7.0.1 using the upgrade assistant which is available in Android Studio at Tools > AGP Upgrade Assistant. The only change it made was to my project-level build.gradle file:
...ANSWER
Answered 2021-Aug-24 at 16:35the Android Gradle Plugin documentation still says classpath 'com.android.tools.build:gradle:4.2.0' instead of 7.0.1.
You need to read further down the page, to this and this. That table is only relevant for pre-7.0.0 versions.
Is this a bug in Android Gradle Plugin 7.0.1?
Quite possibly. Or, perhaps beyond, as the Instantiatable Lint check has a history of problems.
If your scenario does not match one of those three August 2021 bugs, and you are in position to provide a reproducible test case, file a fresh issue! Beyond that, if a clean-and-rebuild is not clearing up your problem, you might need to simply disable the Instantiatable Lint check for the time being by adding the following to all of your build.gradle files at the application or library level (i.e. all except your project-level build.gradle):
QUESTION
I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

QUESTION
Xcode 13.2 Beta release notes features a promise for Swift Concurrency support for iOS 13.
You can now use Swift Concurrency in applications that deploy to macOS 10.15, iOS 13, tvOS 13, and watchOS 6 or newer. This support includes async/await, actors, global actors, structured concurrency, and the task APIs. (70738378)
However, back in Summer 2021 when it first appeared at WWDC it was hard constrained to be run on iOS 15+ only.
My question is: what changed? How did they achieve backwards compatibility? Does it run in any way that is drastically different from the way it would run in iOS 15?
...ANSWER
Answered 2021-Oct-28 at 14:06Back-deploying concurrency to older OS versions bundles a concurrency runtime library along with your app with the support required for this feature, much like Swift used to do with the standard library prior to ABI stability in Swift 5, when Swift could be shipped with the OS.
This bundles parts of the Concurrency portions of the standard library (stable link) along with some additional support and stubs for functionality (stable link).
This bundling isn't necessary when deploying to OS versions new enough to contain these runtime features as part of the OS.
Since the feature on iOS 15+ (and associated OS releases) was stated to require kernel changes (for the new cooperative threading model) which themselves cannot be backported, the implementation of certain features includes shims based on existing functionality which does exist on those OSes, but which might perform a little bit differently, or less efficiently.
You can see this in a few places in Doug Gregor's PR for backporting concurrency — in a few places, checks for SWIFT_CONCURRENCY_BACK_DEPLOYMENT change the implementation where some assumptions no longer hold, or functionality isn't present. For example, the GlobalExecutor can't make assumptions about dispatch_get_global_queue being cooperative (because that threading model doesn't exist on older OSes), so when backporting, it has to create its own queue for use as the global cooperative queue. @objc-based actors also need to have their superclass swizzled, which doesn't need to happen on non-backdeployed runtimes. (Symbols also have to be injected in some places into the backdeploy libs, and certain behaviors have to be stubbed out, but that's a bit less interesting.)
Overall, there isn't comprehensive documentation on the exact differences between backdeploying and not (short of reading all of the code), but it should be safe to assume that the effective behavior of the backdeployed lib will be the same, though potentially at the cost of performance.
QUESTION
In iOS 15, UITableView adds a separator between a section header and the first cell:
How can I hide or remove that separator?
A few notes:
- The header is a custom view returned from
tableView(_:viewForHeaderInSection:). - When looking at the view debugger, I can see that the extra separator is actually a subview of the first cell, which now has a top and a bottom separator.
- Other than setting
tableView.separatorInsetto change the inset of cell separators, this is a completely standard table view with no customizations.
ANSWER
Answered 2021-Sep-07 at 09:21Option 1:
Maybe by using UITableViewCellSeparatorStyleNone with the table view and replacing the system background view of the cell with a custom view which only features a bottom line?

Background
I have a complex nested JSON object, which I am trying to unpack into a pandas df in a very specific way.
JSON Object
this is an extract, containing randomized data of the JSON object, which shows examples of the hierarchy (inc. children) for 1x family (i.e. 'Falconer Family'), however there is 100s of them in total and this extract just has 1x family, however the full JSON object has multiple -
ANSWER
Answered 2022-Feb-16 at 06:41I think this gets you pretty close; might just need to adjust the various name columns and drop the extra data (I kept the grouping column).
The main idea is to recursively use pd.json_normalize with pd.concat for all availalable children levels.
EDIT: Put everything into a single function and added section to collapse the name columns like the expected output.
QUESTION
I'd like to confirm the battery usage of an app I am developing on iOS, specifically on Xcode 13 and iOS 15. (Note: This app previously showed no issues with battery usage on previous versions of iOS.)
Previously, it seems that there were two ways to gather energy usage information:
#1. On the device under Settings > Developer > Logging
- As per Apple's documentation described in the section titled "Log Energy Usage Directly on an iOS Device".
- However, on iOS15, I can't find any options for logging under Developer or anywhere under settings even when searching.
#2. Profiling via Instruments using the "Energy Log" template
- As per the same documentation from Apple described in the section "Use the Energy Diagnostics Profiling Template".
- While it is still available in Xcode 12, this template is missing in Xcode 13. Naturally, it's also not possible to profile an iOS15 device with Xcode 12.
Digging through the Xcode 13 release notes, I found the following:
Instruments no longer includes the Energy template; use metrics reporting in the Xcode Organizer instead. (74161279)
When I access the Organizer in Xcode (12 or 13), select an app and click "Energy" for all versions of the app, it shows the following:
Apple's documentation for "Analyzing the Performance of Your Shipping App" says:
"In some cases the pane shows “Insufficient usage data available,” because there may not be enough anonymized data reported by participating user devices. When this happens, try checking back in a few days."
Well over a year into production and having sufficient install numbers, I have a feeling that waiting a few days might not do much.
I would like to determine if this is a bug in my app or a bug in iOS15. How can energy usage data be gathered using Xcode 13 on iOS 15?
...ANSWER
Answered 2022-Feb-23 at 00:43After contacting Apple Developer Technical Support (DTS) regarding this issue, they provided me with the following guidance.
Regarding "insufficient usage data available" for energy logs accessible via the Xcode organizer:
DTS indicated that they do not publish the thresholds for active users and usage logs would be expected to be present if you have more that a few thousand active users consistently on each version of your app. If your app meets this criteria and still does not show energy logs, DTS recommended opening a bug report with them.
Regarding how to collect energy log data for your app:
DTS recommended using MetricKit to get daily metric payloads. Payloads are delivered to your app every 24 hours and it is then possible to consume them and send them off device.
The instantiation of this is vey basic and can be as simple as:

QUESTION
Apparently, discord bots can have mobile status as opposed to the desktop (online) status that one gets by default.
After a bit of digging I found out that such a status is achieved by modifying the IDENTIFY packet in discord.gateway.DiscordWebSocket.identify modifying the value of $browser to Discord Android or Discord iOS should theoretically get us the mobile status.
After modifying code snippets I found online which does this, I end up with this :
...ANSWER
Answered 2022-Feb-07 at 23:03The following works by subclassing the relevant class, and duplicating code with the relevant changes. We also have to subclass the Client class, to overwrite the place where the gateway/websocket class is used. This results in a lot of duplicated code, however it does work, and requires neither dirty monkey-patching nor editing the library source code.
However, it does come with many of the same problems as editing the library source code - mainly that as the library is updated, this code will become out of date (if you're using the archived and obsolete version of the library, you have bigger problems instead).
