I've been using Ripple (v0.9xx) for developing Blackberry apps using the Webworks SDK (v 2.3.x.x) but just a little while ago, Ripple has stopped working and only freezes when I try to load it up. If I uninstall and reinstall, it starts successfully but then crashes when I try to load an app into the emulator. After that, it will only freeze again whenever I start it. This continues until I decide to uninstall and reinstall after which the cycle starts again.
How do I fix this?
I'm assuming you're using the standalone version of Ripple. We have not switched back to a Chrome extension model with significantly improved performance and stability. You can download the latest version from here:

Ripple should auto-update for future releases from that point on.

I am developing an iOS app in React Native. I have been testing my application on two iPhones - iPhone 6 running iOS 12.4 and iPhone 11 Pro Max running the latest - 13.2.2.
I am having the strange problem that my application restarts when it is minimized in background and not used on the latest iOS. However, my app would continue from where it has been left after long periods of time on iOS 12.4 - in short it will not restart when in background, which is exactly what I want.
I wish to keep my app on the last state the user left it when navigating away from it, so the user can go back and continue their process. How can I fix this? How come an older iPhone with older hardware and older software manages to keep my application running in the background while the newest flagship with its latest software cannot manage it?
P.S. I had the same issue on one of the previous versions of iOS 13. I was really happy when I read that 13.2.2 has addressed this issue and I was hoping it would fix my problem. Unfortunately, it did not.
I would appreciate any ways and guides of debugging this problem and fixing it.
Can you build for iOS with react-native on Windows?
Or does it require xcode?
If so, any work arounds?
I dont want to work on a mac... or a mac vm.
I think the app you create with react-native will work with iOS but you might just have to develop it without an iOS SDK. (essentially, you can't really see the app in a virtual iOS device whilst developing).
However, i think if you develop the app for android using android studio SDK with react native, the app should also work with iOS as well. It's just that you won't really be able to see the app in development on a virtual iOS device.
Another option is to use expo when using react native. Essentially, it displays your app on your iphone so you can technically do app development whilst viewing the app on an iOS device, but I don't think its that great as you can only see it on your phone, whilst I prefer to use a virtual device on my laptop.
You can view documentation for expo in the react native docs here:

I'd recommend you to just develop the app for android using the android SDK from Android studio. This also works with expo or react native CLI. Although you may have to develop the app in a virtual android device, I think the app also works with an iOS device (it may just look a little bit different e.g. a button in android will look different to a button on iOS)
Here's a tutorial that really helped me with learning React-Native:
https://www.youtube.com/watch?v=NuZOwsmzcro
Just follow the steps and make sure you install an android SDK. Then once you get to around "9:25", instead of starting up an iOS emulator from an iOS SDK, start up the android one from android SDK, then hit the button "a" to choose android and you're all set!
The short answer is NO. iOS apps need to build on a Mac. However, if you have a cheap old Mac, or even a Mac cloud account, you can effectively do the equivalent while (almost) never touching the Mac. Of course, this assumes that it has been setup up once, and builds via Xcode or Xcode command line. Once that is done, you can automate it so that you're working and testing only on the PC.
For example, I once took over a React Native project where the previous developer did something similar. Because it was a generic interface, he coded on his PC, then tested via the Android emulator without ever testing for iOS. At that point you can simply push code to GitHub (manually, or with something like Fastlane or a user script). Separately, you have a script on that old Mac or online Mac-as-a-service that checks periodically and builds when the code changes. There were some times when the Mac needed special attention, but for the most part, it worked solely on one machine.
Namely, you can not run IOS Simulator on windows. But you can access a virtual IOS machine and run Simulator from windows virtually as a solution..
My phonegap app is crashing randomly in some ios devices, not happening from phonegap client.
Is there a way to debug an installed ios app with a windows pc ?
Debug a Cordova app is a pain. Since the app is running inside a browser-like, all native debuggers are unuseful. In you specific case, I can suggest you to use Weinre, a remote tool able to show you something as the app is running and you can maybe catch the bug you're seeking.
You can start reading this link or this link and maybe google WEINRE.
Since your iOS app is crashing, most probably the issue will be with the Native Code.
BTW, you can try checking this tool - GapDebug
I have started a project in meteor. a simple counter. I cannot mange to run it on iOS simulator.
I have once managed it to run on the iOS simulator, but not now.
It has proved to be a headache long hours ago, so, I have felt it could be a good idea to ask it here. This situation is inconsistent.
I can view it from my desktop browser and with iOS simulator's safari. But most of the time when app launched, the simulator only shows the meteor splash screen with the spinner. Some times Terminal exists the command with saying it could not started app on simulator and suggesting running --verbose. I do so but nothing changes. In those most cases it serves the web app to the browser. On the other hand I can successfully start my app with android simulator.
I feel confused. After fourth time of writing same piece of this app It is here.
I do not have server code can that be the problem?
Try running with the --verbose option, with this option the full Cordova/Phonegap builds will be logged on console, also work for me when i cannot start the app on the simulator.
I´m looking for memory leaks usign the Instrument (profile). When I run my app on the device, the last vesion of the app is not showed, the Instruments show an old version of my app. If I use the simulator every thing is fine.
Any idea about that problem?
Best regards
