Thanks For #Rado for suggesting the https://apple.stackexchange.com/.
After posting the question on https://apple.stackexchange.com/ i fond the answer.
Orginal Answer: Xcode simulator constantly download something
Answer:
rename the file com.apple.nsurlsessiond(Dont delete) in
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/UserEventPlugins/com.apple.nsurlsessiond.plugin/
to something -com.apple.nsurlsessiond
and also the file nsurlsessiond(Dont delete) in
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/libexec/
to something -nsurlsessiond
Apps with admob works perfectly also no problem with safari
If you don't need an internet connection for testing you application, you could simply disable the network.
You could run wireshark and see what it is actually doing, or at least see where it is connecting to.
I used tripmode firewall don't give simulator internet access only give when you need it.
Works fine but when you forget to turn it off and start the simulator next time, you feel horrible :(

I create a flutter app and now I'm trying to run it through XCode on my real iPhone, but after the installation finishes, I face the following problem:
Also with I trying to run the application on my real phone, after clicking on the application icon, I face a white screen appears, and then the application closes directly.
Catalina 10.15.3
IOS 14.2
XCODE 11.7
Also I was make a trust to app in phone
Does anyone know the reason for this problem?
This problem maybe because of two reasons:
First: Xcode 11.7 doesn't have support files for iOS 14 you can download it from here https://github.com/filsv/iPhoneOSDeviceSupport
Second: I have this problem now and I couldn't fix it.. but I have iPhone with iOS 14.2 and iPad with iOS 14 so the problem was just on the iPhone but after I updated the iPad with iOS 14.2 it happened with it.. so the problem maybe because of the iOS 14.2 so we have to wait for the update or because of the Xcode 11 version and we have to download the Xcode 12 version..
I hope we can find a solution quickly...
make sure to have the latest system update on your target device and the latest Xcode version as well. The error should disappear.
Best,
Ralf
I have fixed the problem by using the above solution but it has happened again. So, I have followed these instructions and fixed again:

A good first place to look is Window > Devices & Simulators in xCode, then find the details for your device. There may be error information here that helps you find the fault.
Restarting devices and installing updates seem to fix this problem for a lot of people.
For me, there was a red notice in the device window about connection to the device and it turned out to be the cable that was at fault.
This was an official Apple cable, just a few months old, and still works fine for charging and data transfer; and I've been using it with xCode without problems for a couple of months. It seems to be possible for Apple cables to develop some tiny physical fault that seemingly only xCode is sensitive to.
Using a different cable worked first time for me.
There seem to be a few variations on the exact error message with the same root causes varying depending on exactly what xCode was trying to do at the exact moment it failed: I'm on xCode 12 and for me it was:
Failed to start remote service on device
Failed to start remote service com.apple.installation_proxy on device
I'm running into an issue where my iMac, with over 100G free, gets Disk Full Error after running Flutter for an hour or so.
When I reboot I get dozens folders in my Trash "Recovered Files" that are around 2G each.
The issue is actually described fairly well here (with screenshots): https://github.com/flutter/flutter/issues/56270
However, the moderator closed every comment as "off topic" (seems like several people are having this problem). So I figured it may be a good idea to bring this here to see if anyone else has found a solution for this?
I'm running VSCode and when I run Flutter Doctor I'm 100% compliant. Using the latest Flutter/Dart/MacOS/Xcode/Android Studio versions. I am primarily building my Flutter app to macOS platform (desktop).
I tried the suggestions in the above issue post and none of these worked for me (re-installing cocoa pods, re-installing Xcode, re-installing Android Studio).
I actually ran into this issue about a week ago. The comment linked to had put me on the right track, where they mentioned it only happens when they have an iOS device attached to their machine.
If you see something like this error in your VSCode output log when launching your app, then it's likely the same issue.
Failed _shouldMakeReadyForDevelopment
If you have a device attached and it's locked, I believe something in the Flutter env attempts a connection over and over causing these files to fill up.
However, this happened to me once even when I didn't attach a device and I found out it was because I had "wirelessly" attached a device in Xcode when I was doing iOS development for another project. So just sitting at my desk with my iPhone nearby was enough to cause it to try to connect over and over again, even if it wasn't attached.
I removed my iPhone from Xcode's wireless device list and that seems to fix it.
Can confirm, running flutter with an attached ios device eats disk space.
This is happening to myself and another developer on my team. I lost 200 GB of disk space yesterday. It's a frustrating productivity killer.
I am using the latest flutter
flutter doctor reports everything as fine
xcrun --find simctl is fine
Using Android studio 3.6.3
Latest patched Catalina 10.15.4
This morning I opened the Android Studio IDE with an android device and an ios device connected. I opened a get info window on my hard drive and left it open. Then I did nothing but watch the info window. No builds or anything. Over the course of a couple minutes, I watched 7 GB disappear.
I shut down the IDE and the loss stopped. I reopened the IDE with only the android device attached. I waited and watched for a few minutes. No loss of disk space.
Then I reopened the IDE with just an ipad attached and the losses started again. Then I unplugged the ipad and left the IDE open and the losses stopped.
Same here but happens also when just running Android Emulator.
This needs to be fixed A.S.A.P - its a dealbreaker!
When the problem happens and the disk runs full, my system slows down so much I can hardly do a thing. To free up disk space and get operational again quickly, there's two options:
Restart. Then the cache files are either deleted or end up in "Recovered Files" in Trash, as described by #william-t, from where you can delete them.
Directly delete the cache files in "TemporaryItems" (for me that's below /private/var/folders/bc/gw57z9dn4rn2v6df7306k9sh0000gn/T)
I know this is not a solution to the root cause of the issue, and it still helps a lot, as long as there's no true fix...
i recently received my Macbook and wanted to start developing iOS apps with it.
I Created a default Master-Detail App using the Templates in Xamarin.Studio and everything worked.
Now today i wanted to actually do something in the app, but didn't change a single line of code, still the app doesn't show up anymore in the simulator as long as i want it to use the 6.1 sdk for ios. if i use any other (6.0 etc) it works fine.
I already tried clearing my Cache in /Users/MYNAME/Library/Xamarin/ but this didn't change anything.
What would you suggest me to do now? can i simply reinstall the 6.1 sdk?if so, how would i do this?
Thanks for your help
I had a similar problem where the environment hang when I was trying to debug in the simulator (just showing the spinning ball). I found out that it only occured if I had my phone connected to the computer. Perhaps not valid in your case, but it might be a lead in your problem solving.
I'm using the latest version of everything. :)
From within Xamarin Studio (or MonoDevelop):
Project -> Your.Application.Name Options
Build -> iOS Build (iPhone Build in MonoDevelop)
SDK version: -> 6.1 (it's probably still on 6.0)
This fixed it for me. Also, it wouldn't hurt to make sure the target build in info.plist is set to 6.1.
Delete this folder:
/Users/[username]/Library/Application Support/iPhone Simulator/6.1
And if your Library folder is hidden:
sudo chflags nohidden ~/Library/
I have experienced this problem several times again and my previous answer doesn't solve it. Ya know what does? Rebooting the computer. Works every time. shrug
You need to fill the Application name, Identifier, Version # in the project setting.
I had the same problem and got it solved that way.
The "verifying application" step of the build process in fully updated XCode 4.6 (and previously 4.5) often takes upwards of two minutes on my machine. Coworkers building the same application on similar computers have this step take only a couple seconds. My machine used to, as well, but does not anymore, for the past few months.
Does anyone know what could be causing this and how I can fix it?
Update your device to the latest version of iOS, 6.1.
Had the same issue, fixed after updating my iPad3.
Try rebooting your device.
I had the same problem using XCode 4.5.1 and an iPad 6.0.1, but didn't want to update at the time. In additional to a long 'Verifying Application' step, I noticed that copying resources over was also slower. After that, I disconnected the iPad and tried to delete my App, but discovered that even the device's delete alertview took several moments. So, obviously, for me, this was a device issue, and after performing a shutdown / restart of the device, xcode performed up to previously normal speeds.
When I compile my mobile app using Xcode and Phonegap, the application on the iPod/iPhone/iPad is the anterior version that I compiled yesterday.
Basically when I run the app in the emulator, all works fine, so I know it's the right files and everything, but when I then build it for the mobile device, it shows the one I did yesterday.
What could be causing this? Is there any settings I should check or something? Like I said I doubt it's related to the files/folder because when emulating it, it works fine.
Thanks!
I had a similar problem long time ago. Try to delete your app on the device and then build it again. I don't know how apple manage apps but I think that the major of your app is keeped on your device (in order to speed up compilation).
I hope it will works !
Did you increase the version number of your built? If you recompile with the same number, you may run into trouble.
