Worklight 6.1 - Sometime app stuck with splash screen in IOS - ibm-mobilefirst

I observed so many times that app get stuck with splash screen and nothing happens in this case. We are getting below logs on Xcode console at that time.
2014-01-20 13:09:14.822 MyApp[4326:a0b] Resetting plugins due to page load.
2014-01-20 13:09:34.924 MyApp[4326:a0b] Failed to load webpage with error: The request timed out.
This is just a default application with index.html page and text Hello Worklight in it.
This is tested on IOS6 and IOS7 simulator and device both.

I found some similar posts at the following locations describing this issue with Phonegap/Cordova. Some of the solutions/suggestions may help:
Phonegap/Cordova 3.1 Resetting plugins due to page load
Resetting plugins due to page load - Issue
As well as a bug report in Cordova:
https://issues.apache.org/jira/browse/CB-2602

I found a bug in worklight 6.2 + iOS 6(with a fix) that might also solve your problem, if you're having the same issue.

How can I fix enterprise app distribution for React Native on iOS13?

I have a React Native application and I use Expo. It's distributed to enterprise through a download link and not through the app store. The ipa works on iOS13 devices, and the download works for ios12 and below, but stopped working from ios13. If anyone encountered and knows why would be thankful.
We have found out that the reason the link is not causing the download is a JavaScript animation we had at the web page where people download the app from. This animation allowed downloading the app on iOS12 and below, on all browsers, and prevented downloading in iOS13 on all browsers.

Error when uploading to iTunesConnect

I am using Application Loader to upload my .ipa files (created with Adobe AIR v18) to iTunesConnect.
It's been working fine for months, but today I received two new errors:
The u option must have a non-empty value.
The password must have a non-empty value.
Can anyone shed some light on the issue?
I upgraded to Xcode 7.1 and that solved the problem!
Note: Xcode 7.1 comes with Application Loader 3.3.
You have 2 solutions:
1) Update your Xcode to 7.1 (but since you are not coding natively, use the solution #2 below)
or
2) Download and use the Application Loader v3.1 (Download link: https://itunespartner.apple.com/en/apps/tools ) to submit your IPA
Apart from low-belly's answer you can try to use XCode's built-in upload feature. If you go to the Organizer, just click on Upload to App Store:
This solved the problem for me in XCode 7.0.1.
Xcode 7.1 was downloading too slow (more than 4GB) and the update failed every time, so for now I downloaded the Application Loader 3.1 from iTunes Connect and it worked fine.
To download it you login into iTunes Connect -> Resources and Help -> click on View Tools (under the title Other Resources at the bottom of the page) and there is the download link.
I got the same error last night. Fixed it by signing out of Application Loader (3.6) and logging back in.
I got the same error with Application Loader 3.2. Submitting with Application Loader 3.0 (bundled with Xcode 6.2) or 3.1 (bundled with Xcode 6.4) solved the problem.

Using Worklight JSONStore

I am not that new to Worklight, but the JSONStore is a new feature and I'm trying to learn how to use it. I downloaded the sample app (module_07_10_Using_JSONStore.zip) and installed it in my development environment, ran build and deployed it.
When I preview the app (as Android) in the Mobile Browser Simulator, and run through the sequence of Initialize the Collection, Add a Document, and then try to Find by Name, Find All, or get Number of Documents in Collection - I do not see the table at the bottom of the screen that displays the input data. I don't see any errors in the WL console. In the Android console, I get the error messages:
Unable to resolve target 'android-8'
WARNING: unable to write jarlist cache file - and then it points to location of jarlist.cache in the module.
I did not make any changes to the code. I looked it over, compared it to the education module content, and I don't see the problem. Any thoughts? Clues? Your help is appreciated. Thanks.
JSONStore is not supported in the Mobile Browser Simulator, it must run on an Android or iOS device or simulator, if you run it on the Android simulator it should work just fine.

Sencha 2.0 App file size issue -

I have developed a small Sencha Touch 2.0 app. Here is the url:
http://apps.swarnendude.com/sencha/iphonetest/iphoneTest.html?url=http://apps.innofied.com/sencha/gts
The app works in perfectly fine in Android 2.3, iPad, iPhone, Blackberry Playbook. But the app crashes while I test in Blackberry Torch (OS: 6.0) giving this error:
"The page you requested could not be loaded. It is too large for this device"
The production version of the file sizes are:
sencha-touch.js: 90.5Kb
app-all.js: 401.4Kb
app-all.css: 151.5Kb
Other resources: 10Kb
So, total around 650Kb. I think the sizes can be reduced more but I am not getting any other options. I am using the least css configs in SASS file and in JS too (only which are required). Is there anyone getting the same problem? Any solution?
It seems that you attempted to minimize your app, so in this case, there's not much you could do.
I'm using Blackberry Bold and occasionally see this when I use native browser. But in some cases, Opera Mini and Bolt Browser are good suggestions to pass those errors.

iOS application crash when started

I have such problem
I am making an application with xcode 4.3.1 iOS 4.0 as target.
I have default picture as starting image.
I am using core data.
When I start application then type some info into it and then push it to background. Its all ok. If I try to start after I went to background it become crash after start image is loaded. Second launch is good without crashes. When I try to start application with some delay it does not crash.
The problem that I have no errors in debbuger and no logs about crash in iPod. All seems well.
If you had such problems, please say how you fix this issue.
P.S. Sorry for my English
You can try using logs and check out Xcode's organizer's console for your device so you can get additional info about functions that were called last.
