I am trying to run a Xamarin.Forms app on my iPad and getting the following error:
Launch failed. The app 'AppIOS' could not be launched on 'My iPad'. Error: error MT1006: Could not install the application '/Users/mycompany/Library/Caches/Xamarin/mtbs/builds/AppIOS/someguid/bin/iPhone/Debug/my.app' on the device 'My iPad': EOF Error (error: 0xe800000e).. Please check the logs for more details.
This app has previously ran fine on the same device. The iOS build and deployment process seems very unstable so it often takes multiple attempts so I'm used to having to restart Visual Studio, the Mac it builds on and the iPad and generally wasting a whole lot of time. I have restarted everything involved here multiple times but this error persists. I have checked the device logs and there are no related messages or even any messages at the appropriate times.
I'm using Visual Studio 2017 (15.9.4), Xamarin.iOS and Xamarin.Mac SDK (12.2.1.12), building on a Mac Mini running macOS Mojave and XCode 10.1, deploying to an iPad Air (A1474) running iOS 12.1.1. As far as I'm aware there have been no updates to any of these since I last had it working. The UWP version of the app runs fine.
I can find a lot of MT1006 issues but none with EOF Error (error: 0xe800000e) and I can find no information about this specific error at all. Can anyone enlighten me on what this means?
Sounds overly simple, but I just had this issue and I solved it by restarting the iOS device and redeploying it. Specifically, I was deploying to an iPod 6th Gen and I held the power and home buttons until the screen turned black, this is more of a hard restart. Then let the device reboot and try deploying again.
NOTE: Don't hold the power and home buttons too long, because if you do, the iPod will go into a factory reset restart.
Try pulling up the device in Xcodes' devices tab. I did and realized the device had an error within the tab. I then disabled the "Connect via network" button, then things started to work properly.
I am agree, Xamarin build environment on iOS part is very buggy.
In any case of unknown error in such config: VS<->MAC<->iOS Device try these steps:
Try to switch Off and On Mac wifi.
Reconnect VS to Macbook and Macbook to IPhone.
Delete bin and obj folders on Macbook
Check your PList and Entitlements file(as example wrong aps-environment setting can cause installing errors)
Check your sign project settings
5a. Check your provisoning profile term
unistall application from ios
rebuild and run project again
I'll appent new lines in case i'll remember something else.
What you described happened to me and solved by 1,2,7
I am having troubles using my iPad as a testing device for my Xamarin.Forms App Running in Visual-Studio-2017. I have already done the requirements to use my own app but it still doesn't show on the devices. Here are the steps I have done so far.
Created my own account on free provisioning as described on this site. https://learn.microsoft.com/en-us/xamarin/ios/get-started/installation/device-provisioning/free-provisioning?tabs=macos
Opened my Xcode and created an empty app to setup the free provisioned account as described on the link above.
Fixed my the codedesign keychain access by inputting my Mac password and clicking always allow
Changed my info.plist information on signing as shown below
On bundle options, I have changed my signing identity and provisioning profile created by xcode. and changed the platform to iphone and clicked ok. See the image below.
After I clicked ok, Visual Studio says it was saved. But everytime I checked on my a debug device, it only shows simulators! Shown below:
I have tried restarting visual-studio mac numerous times but still how the same result! My devices hasn't shown at all!
I have scoured the internet and I couldn't find any concrete solution.
I was able to find the solution. Just change the Debug to Debug | iPhone as shown below... And it will show your device.
I installed ipa for a worklight application in iOS8 ipad. While opening the application it is showing error as "Cannot find 'app-name''version'in this ipad". What could be the reason for this??
It sounds like the project is being incorrectly signed/generated in Xcode. Possibly due to wrongly given values.
When you create a new project in Worklight Studio > add iPhone environment > Build > Open in Xcode > Run, does the app get successfully installed and launched in the iOS Simulator/device? My guess would be that 'yes'.
Open the info plist file and verify the application parameters are correct. Have you changed these? or anything else?
I can't debug my app because when I run it, Xcode gives me the error:
Process launch failed: timed out trying to launch app
In the device I see a black screen and after the error message the app starts.
How can I fix this?
I tried to change the code signing identity and the provisioning profile, and to refresh the provisioning profiles in the Xcode > Preferences > Accounts > Details tab.
I'm using Xcode Version 6.0.1 (6A317) with an iPad mini, running iOS 8.0 and a MacBook with OSX 10.9.4.
After this, if the iPad goes into sleep mode (the screen turns off) I can't wake it anymore; I have to do a soft reset.
You are using distribution provisioning profile rather than development profile. check this link
How to Fix:
I fix it with:
clean project (Product > Clean)
hard reset device (power button + home button)
delete app from device
close xcode
CLOSE ITUNES (itunes must be closed)
re-open Xcode and run!
I think that iTunes was the problem.
EDIT: 2017/02: Solution still Woks (Thanks to #SalGad for information).
I am using Xcode 6.2, running on iPhone 4 with iOS 7.1.2, the problems happen to me as well.
It turned out that the Project and Targets' Code Signing settings are different from each other! And that's what is causing the issue.
To solve the issue, you must make sure that their Code Signing settings is the same.
One more thing that may be a reason to launch timeout arising is that you have a lot of Provision Profiles on your device. I have about 100 of them, downloaded automatically by XCode from our team dev portal. So if your team have tons of apps and Provision Profiles, you better unlink your XCode from your Apple ID, to prevent automatic downloading for unwanted PPs. It significantly decreases app launching time.
To delete unwanted PPs from your device you have to go XCode - Window - Devices, select your device and click "Show provision profiles..." on the bottom context menu. Then you have to manually remove the profiles. Tip: use key sequences "down arrow" - "backspace", to ease the hand routine.
I had this but nothing previously posted seemed to work. This is what I did to fix the issue in Xcode 6.3.2:
Go to Product->Scheme->Edit Scheme...
Select the Run Scheme
Select the Info tab
Make sure the settings are as follows:
Build Configuration is set to "Debug"
Debug Executable is checked
Launch Automatically is checked
In my case I was using the development profile, but somehow, in Build Settings > Code Signing, the Provisioning Profile for Debug was empty.
But before setting it to "iOS Team Provisioning Profile", I had to reset my account since it said " is Not on Any Development teams"
- Xcode > Preferences > Accounts
- Remove my account (click "-")
- Add the account again
That fixed the problem
Note that if the app still manages to start on the device after Xcode displays this error, you can attach to the running process with Debug->Attach to Process.
This warning is shown when you try to run and debug your code directly in device but you are using distribution profile in your Build Settings.
To directly run the code in device and debug, you need to use development profile in your Build Settings of Xcode.
After setting the development profile, just reboot your device clean your Xcode project and run again.
I hope this helps !!
An app should return from his initialisation procedure in less then 10 seconds, or it will be killed by the OS. This is probably because you are doing too many things in the startup phase.
Try to refactor your code to do it diffrently, by doing lazy initialisation, and only initialize what is really important before showing the first view.
It's hard to give better advice before knowing more about the app itself
I have faced this issue with Xcode 6.2 and Iphone 5s with iOS version 8.3.
I get this message when I deploy the application to the device for the first time.
The work around I found was that with out unintalling the application from the device,redeploy the application from Xcode.It should run perfectly this time.
I observed this only on Xcode 6.2 not on Xcode 6.3 so this might be an Xcode to iOS version compatibility issue.
Big and weird tip for this problem... this was happening to me and none of the advice helped anywhere on the web, but then i noticed if i deleted everything out of the main ViewDidLoad method it would work. I realized there was one line of code that was messing it up. It was a line that was referencing to an array of strings that was way to big. I had something like this NSString *mystring[100][1000][100]; i accidentally added some zeros and for whatever reason this problem produced the same error message that the incorrect signing gives you. So don't let your arrays or matrixes get too out of hand!
Method #1:
Lock your phone, press XCode start, wait till XCode says "unlock your device to launch", then unlock your phone, it will be launched successfully, works every time.
Method #2:
If your goal is just to debug the app, here is another simple and straight-forward approach:
After the app is deployed, launch it manually.
Goto XCode -> Debug -> Attach to Process ... to choose your app from the list, then debug properly.
This works well for me, and it saves lots of time.
I hope this helps, thanks!
We've built an MDM server using a mac mini.
We have 2 applications to push out to a number of users. One app will push and download on the remote devices with out a problem. The other displays an error "The app could not be installed at this time"
This second application is an older application.. however we are building it for 6.0. In the console we see this.
ipad SpringBoard[65] <Warning>: could not save thumbnail for downloading icon: image=(null) path='/var/mobile/Library/SpringBoard/DownloadingIconImageCache/
This app can be built an installed when a device is connected to the build computer. We have all of the signing the same as the first application. We can also archive the app without any errors. What would cause this app to not install, or what should we start with?
Several notes/ideas:
a) Take a look at this (they mention the same problem)
Trouble installing AD-HOC distribution through safari
iOs application crash on install
Ad-hoc distribution fail
http://community.phonegap.com/nitobi/topics/not_installing_my_application_in_ipod
b) Can you please post your manifest (if you are installing inhouse apps)?
Please double check that that if you pointing to icons in this manifest, the links are correct.
Ok this took days to figure this out... In my situation at some point another icon was added into the build settings. We did change the name of the bundle so I'm assuming that xcode automatically populates the icon information?
In the info tab check to make sure you only have one property for 'icon files' (to be clear you should have the ability to open the drop down menu and expose sub menus... What I had was 2 'icon file' sections.) After I deleted the second set of icon files it pushed fine.
Hope that helps others figure out a very frustrating situation
