instant | A std : :time : :Instant replacement that works on WASM

I managed to find the cause of this issue. I opened my project using android studio (just open the android folder only) and tried running it from there and the emulator was showing

Unable to load script. Make sure you’re either running a Metor service (run ‘react-native start’) or that your bundle ‘index.android.bundle’ is packaged correctly for release.

P/S: The error above didn't show up when I do npx react-native run-android.

Found this very helpful article React Native: Unable to load script: index. android.bundle

What I did was, in the app/build.gradle there is this line project.ext.react and added bundleInRelease: true since I want to generate a released APK. And simply run gradlew assembleRelease from the android folder.

The problem is in two lines of your code. First, as noted in comments,

Well.. this seems to be an iOS bug.

I have cerated a sample project here that shows the bug... https://github.com/oliverfoggin/BrokenImagePickers

And a replica project here written with UIKit that does not... https://github.com/oliverfoggin/UIKit-Image-Pickers

I tried to take a screen recording of this happening but it appears that if any screen recording is happening (whether on device or via QuickTime on the Mac) this suppresses the bug from happening.

I have filed a radar with Apple and sent them both projects to have a look at and LOTS of detail around what's happening. I'll keep this updated with any progress on that.

After a bit of further investigation I found that you can start with SwiftUI and then present a PHPickerViewController without this crash happening.

From SwiftUI if you present a UIViewControllerRepresentable... and then from there if you present the PHPickerViewController it will not crash.

So I came up with a (very tacky) workaround that avoids this crash.

I first create a UIViewController subclass that I use like a wrapper.

Welcome to dependency hell and breaking changes in libraries.

This usually happens, when various lib bring in different version of same lib. In this case it is Jackson. java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; means: One lib probably require Jackson version, which has this method, but on class path is version, which does not yet have this funcion or got removed bcs was deprecated or renamed.

In case like this is good to print dependency tree and check version of Jackson required in libs. And if possible use newer versions of requid libs.

Solution: use libs, which use compatible versions of Jackson lib. No other shortcut possible.

You said:

The output gives the same instant:

An Instant is a moment as seen in UTC, that is, with an offset from UTC of zero hours-minutes-seconds. So your code makes no use of your specified time zones.

Instead, try ZonedDateTime. This class does make use of the time zone. For example, calling ZonedDateTime.now() captures the current moment as seen in the JVM’s current default time zone. Calling ZonedDateTime.now( myClock ) captures the current moment tracked by that Clock object as seen through that Clock object’s assigned time zone.

You need to play around with the animation duration and also adjust the key frames percentages -> the tween in when you are flipping the text using your transform/opacity rules.

I have slightly adjusted each, but this comes down to a taste in how you want it to look and feel. Spreading the flipping animation over more of a percent (your tween) will lessen the amount of time you have in a pause between animations.

Register Jackson ParameterNamesModule, which will automatically map JSON attributes to the corresponding constructor attributes and therefore will allow you to use immutable classes.

In JS, all numbers are floating-point thus division/modulo are performed on floating-point.

However, in current processors, integer division/modulo are much slower than floating-point ones (see here).

In your Rust program, the modulo is naturally computed on integers. When artificially switching to floating-point, I get a substancial improvement (310ms --> 152ms).

Your date string doesn't include a timezone, so it cannot be parsed directly to a ZonedDateTime (see javadoc for ZonedDateTime#parse).

Try parsing the string to a LocalDateTime instead (using LocalDate#parse).

You can then convert the the LocalDateTimeto an Instant using LocalDateTime#toInstant or to a ZonedDateTime using LocalDateTime#atZone
