When I launch my app for simulator-iphone (ios 8 or ios 9), all works as expected.
When I launch it for simulator-ipad with ios 9, system freezes with LaunchImage displayed. (ios 8 is fine however). The last thing I see that has been called is applicationDidBecomeActive in AppDelegate.
The console is empty.
After waiting quite a long time (a few minutes) with CPU being at 99% app crashes with a very long system tack:
To note that it only crashes when user has Base language selected. With any other language there is no crash. I have checked all my localization files, but cant find any problem.

I have a XF app already published on the play store and now I am targetting iOS. During developpent I made sure the app was still working on iOS, using the simulator only.
On the simulator everything works as expected, the launch screen is shown then the MainPage starts. But when I debug on an actual IPhone device, the app get stuck on the Launchscreen.storyboard for about 20 sec then the app exits. I've no debug output and it seems that the AppDelegate is never hit. Breakpoints in AppDelegate.FinishedLaunching method are not hit for instance. I tried to F11 for start in debugging mode but I don't hit anything, still hanging on the launch screen. I was expecting the transition from simulator to device to be less painful.
My plist file contains the following permission requirements
...
<key>NSLocationAlwaysUsageDescription</key>
<string>We need to use your location</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>We are using your location</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app needs access to photos.</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>This app needs access to the photo gallery.</string>
The only difference I saw is that location permissions are not asked on the device while in the simulator it asks for it at start. But this might be related to the fact that I can't reach AppDelegate, I am not sure yet.
The iOS project was generated via Prism templates. I am using VS 16.8.0 on Windows, XF 4.8.0.1687, Prism 8.0.0.1909, Xamarin iOS SDK 14.4.1.3 and I am set to "don't link" for linkers option. The device is an Iphone 10.
Any idea how can I find out the root cause - or get some useful logs?
Thanks in advance for your help.
EDIT:
Here are the device log output during a new installation https://taits.s3-eu-west-1.amazonaws.com/devicelogs.txt. I am trying to go through them but kinda lost.
Our test automation sometimes makes the simulator crash. In these cases, we often see the dialog below throw on the simulator's next launch. This modal UI dialog breaks automation by preventing application execution until the user chooses an action.
When the iOS Simulator crashes, the application state may be saved in ~/Library/Saved Application State/com.apple.iphonesimulator.savedState. The presence of this folder or values in the data within triggers the modal dialog.
Removing this folder (rm -rf "~/Library/Saved Application State/com.apple.iphonesimulator.savedState") before restarting iOS Simulator will prevent the dialog from appearing. This has been tested with iOS Simulator shipped in Xcode 9.4.1.
I've had an Apple Watch App hosted in an iOS App rejected for:
"We discovered one or more bugs in your app when reviewed on Apple Watch.
Specifically we found the watch extension continues to load indefinitely on launch."
In the simulator and on the watch itself (iOS 9, WatchOS 2, xCode 7.01)
None of the visible routines are repeatedly called, and I can't find a starting point to debug this.
The watch app has no notifications, no glance interface, and has a single story on the storyboard. It does contain a WKInterfaceTimer which I "stop" and "start" on activate and deactivate, but of course the underlying timer is not stopped or started. I don't even know what they are seeing that causes this report. So tough to debug. Any ideas?
That's WatchOS bug. See related discussion on ADF.
I'm using Xcode 6.1 and iOS Simulator 8.1. It takes a long time to run the simple apps that I've written using the iOS Simulator. Build process was ok but then the iOS Simulator will show the black blank launch screen then the app screen for like 5 minutes before the app launch. Many times it shows error "Lost connection to iPhone 6(/5/4s)". Tried to re-start Xcode and iOS Simulator, and MacBook Pro multiple times already. Tried to reset "Content and Settings" in the iOS Stimulator, but doesn't help.
What could be the possible causes? Any advice/solution? Thank you.
I suggest that you boot up the device that you want to use prior to the Build&Run in Xcode. If you hit Build&Run in Xcode while the device is not booted, you will need to wait for the device to boot. This can take a long time depending on your I/O load (eg: if Spotlight is indexing at the same time you are trying to boot, or if your home directory is on a slow volume like a network mount).
Just open up iOS Simulator.app ahead of time and select the device you want to test on from the Hardware->Devices menu. Then it will be ready when you need it.
Make sure 'slow animations' is not selected under the Debug tab in the iOS Simulator. That fixed the issue for me.
Googled on this issue and some said it's a Xcode bug with the 6.1 beta, but I had the 6.1 release version installed alreadt. I even try the 6.2 beta, hoping Apple has a fix for this, but no luck, still the same.
So desperate that I decided to upgrade my 3 years old MacBook Pro RAM and harddisk to SSD. Problem solved with the upgrade! The iOS Simulator runs normally now.
My window phone 8 emulator not able to start when I run program from vs2012 emulator start loading after some time emulator automatic shut down. when I see the progress of running emulator while running program in Hyper-v there showing window log and emulator stop and again start, this will happen many time and after some time emulator off and in Vs2012 showing Deployment fail.
But before I tried it works properly, when emulator run emulator that time internet is not available show I searched in Internet for solution I removed network switches and run Xdecleanup but problem is still persist.
My Machine Configuration:
Processor : Core-i7 2.20 GHz
RAM : 4gb
Graphics : 2gb
HDD : 1TB
Hypervisor : Present.
Software : Visual Studio 2012
SDK : Window Phone 8
step 1:Goto Hyper-v manager
step 2:Choose file menu and click on options. Options dialog opens in that click on delete files button. You are ready to go now.
This worked for me.
