I noticed when I develop apps using different Macs(i.e. office-Mac and home-Mac), every time I plug the iDevice(iPhone, iPod...) with Mac, click the View Device Logs button under Window -> Devices and Simulators option, there are some (crash)logs in one Mac and others in another Mac. Or sometimes
My question is:
why this is the case?
How can I view all the logs in one Mac?
Is there another way to view/analyze (crash) logs of iDevices correctly and conveniently without using Xcode?
Here is my environement:
macOS: High Sierra(home-Mac), Sierra(office-Mac)
Xcode: 9.2, 8.3.3
iDevice: iPhone SE(iOS 10.3.3), iPod Touch 5th-Gen(iOS 8.2)
Many thanks in advance.

I updated to the latest AppStore release of Xcode (12.3, 12C33).
It worked fine for an hour or two. After that it started to constantly freeze after being open for a few seconds to minutes.
I've tried the following, all without success so far:
restart macOS
clear derived data
tried with different projects
updating to latest macOS 11
Any other ideas or suggestions how to fix this?
Update
I can confirm that this is fixed in Xcode 12.5
I found an answer by Darr on the question "Xcode freezes after upgrade to 12.3" on Apple's developer forums that worked for me:
Unpairing my device connected via network and using only lightning cable seems to have resolved the issue for me.
Xcode > Window > Devices and Simulators > device > Connect via network
After going mad, I fixed this by removing all devices from Devices and Simulators (I had connect via network activated).
For now, it's working fine.
Power off your Apple Watch
Xcode may hang if the host Mac is connected to an iOS device which has one or more companion watches. The hangs occur when the watches aren't fully prepared for development, or if they are experiencing poor wireless connectivity. (72490921) (FB8945320)
Workaround: Power off the watches, or unpair them from the iPhone.
Xcode 12.4 Release Notes
You can force Xcode to freshly prepare a watch for development using these steps:
Force-quit Xcode.
Power-off and disconnect all iOS device from the Mac.
Reboot the Mac.
Launch Xcode, close all projects, and open the Devices and Simulators window.
Power-on and unlock an iOS device and its companion watchOS devices by entering the passcode as required.
Plug the iOS device into the Mac using USB cable.
Check each iOS device and each watch for any pairing request and approve the requests.
Monitor the status of device preparation in the Devices and Simulators window. If Xcode presents device-preparation errors, follow the guidance in the error message to resolve the error.
Once Xcode finishes preparing the iOS device and its companion watches for development, repeat steps 5 through 8 for each remaining iOS device and its companion watches until you verify that Xcode has prepared all devices for development. You may now open your Xcode projects and resume development.
I've been having the same problem. I had an iOS device connected via USB, unplugged it and it un-froze. Then I continued to have issue requiring force close each time.
I then clear derived data and things have been fine. I opened a StickerPack project and also had the same issue. Clearing DerivedData also fixed it.
Clear Derived Data:
Xcode pulldown menu > Preferences > Locations tab
Click the little arrow next to the path under Derived Data.
Delete the entire folder for you project. It will look like "MyAppName-bwonddotztrgkkfexrjxoncvmjit"
See this explanation about whether it's safe to delete DerivedData for your project.
I had the same problem with appstore version and someone advised to install from site, now it works fine. https://developer.apple.com/download/more/
Disable WLAN on my iMac fixes the problem currently.
Hope they will releast a fix very soon.
Xcode 12.3 is unstable and many times it crashes.
I reverted back to Xcode 12 and copied disk image of 14.3 in Device Support folder of Xcode (Contents > Developer > Platforms > iPhoneOS.platforms-DeviceSupport).
This I needed to debug on iPhone device having version iOS 14.3
https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases
I recently had similar situation. My Xcode 12.3 project could not be opened. I tried to open directly from popup that appears on start of the Xcode.
What worked for my was to downgrade Xcode to 12.2 and launch Xcode on new project. And then click my old one.
Maybe it would work without downgrading but I didn't check.
I had this problem too. I fixed it by going Devices and Simulators in the Windows file and disconnecting the iPhone reference I had for my phone when testing and app. Since the phone was no longer connected, its presence seemed to create a freeze.
In my case XCode 12.5 hangs/freezes on startup more or less instantly, right after it opens kind of an empty workspace.
I removed everything that I could imagine that deals with XCode on my machine, but it didn't help.
At the end I just used the hotkey for "Close Workspace" - Ctrl+Alt+Cmd+W
I hit this combo very often, very fast right after opening XCode and it worked!
The strange empty workspace showed up and closed instantly - now I could select other projects and everything works again.
There could be the multiple reasons and in my case reason was source control
preferences > Source Control > uncheck Enable source control
I have these performance problems with the newly updated Xcode from the AppStore to 12C33 (Xcode frozen for many seconds, instability of interface builder, etc.) only with apps which have frameworks added with cocoa pods and when working in the xcworkspace-file. (Integration of frameworks with Catharge even fail with error message 65). I'm running Xcode under macOS Catalina. Don't know what the technical reason could be, hence would appreciate if someone has an idea on this how to fix it.
Update: In the meantime I could fix it:
I eliminated my own devices from the device list and did then a deintegration and a new install of the cocoa pods for the projects. Afterwards I setup my devices again in the device list and all worked well again. Only eliminating and reintegration of my devices as described above didn't work in my case.
When using the simulator under Xcode 11.3.1 and iPhones simulating iOS 13.3, the simulation does not behave correctly. It works correctly under simulator iOS 12.1.
I get no messages that I don't also get under the iOS 12.1 simulator launch.
The behavior should be when a user starts the app for the first time, he is redirected to the signin screen. Instead it goes to the main screen (grayed out because there is no data). I can navigate manually to the signin screen and signin normally (device registers and appears on my online server) but the app should start downloading the database required to work. It just sits there (no alertview that would normally launch the download). If I relaunch the app, it again starts at the main screen, however at this point an alertview should appear that no database is present. If I manually try to start the download (in a setup screen within the app), the progress bar that normally appears does not, just a label signifying what database is suppose to download.
All of this works properly on the iOS 12.1 simulator (Xcode 10.1) of the same type (iPhone 8 Plus).
Is this an Xcode 11.3.1 bug or iOS 13.3 problem. I have customers using iOS 13.1 without any problems on actual devices. I am on a new iMac running Catalina, is it possible its a security setting to allow database download?
I was facing the same issue and I move back to Xcode 11.3. Guess it was not a stable update at all.
I upgraded my iPad device OS version recently to 5.1.1 (9B206). From that my Xcode is not detecting my device. Am just getting iOS Device and simulator options in my Xcode. But am getting my device in older version of Xcode and iTunes. For this i updated my MAC OS version to 10.7.4 and Xcode version to 4.3.3. But still am facing the same problem. Now how to make my Xcode to detect my device?
This Worked for me.
Quit Xcode.
Disconnect the device.
In a terminal window, type: sudo pkill usbmuxd (it will be restarted
again automatically)
Restart Xcode
Connect the device
Your device should now be visible again in Xcode!
Open the Organizer in Xcode, go to devices, find your device and click the option to use for development
I just plugged into another USB port and it detected by device.
In another case, check the "iOS Deployment Target" in "Build Settings",
if the target iOS version number is great than the version of device,
then the device will not show in the list.
Say that, the "iOS Deployment Target" == 7.0, and the version of device is 6.0,
to solve the problem by change the "iOS Deployment Target" to 6.0 or lower.
If the chosen answer still does not work for you try this:
Select the project in project explorer
Select the target on the main window
Select Build Settings
Select Deployment
Select iOS Deployment Target. Change it to the version of your device. (e.g. iOS 5.1)
I was also faced the same issue in Xcode, my device was not detected after update the Xcode latest version(7.3.1)
Done so many things what suggested in the web-search but still the device was not detected.
Finally, I just quit and open the Xcode my device was detected(oh my bad).
This SO answer solved it for me https://stackoverflow.com/a/56054170/5813473 .
sudo killall -STOP -c usbd
did the magic.
Well later I had to unplug/plug in again at occasions, but that 'killall' really solved the original issue.
Most recently, Xcode 8.3 and iOS 10.3 seems to have more security around Xcode accessing the iPad/iPhone. My sequence:
Rebooted the machine,
Attached the iPad,
Gone through a "trust this computer" security cycle on both iMac and iPad
Xcode can now see the device
Sometimes restarting Xcode helps. Give it a shot.
In my case, restarting Mac worked and no other solution.
I updated my iPad (it's in Settings -> General -> Software Update, near the top) and restarted my computer and Xcode sees it now.
FWIW I tried all the tips in this thread and nothing would work: from reboots, command line statements, unplugging, different USBC ports, etc. I also tried something not mentioned here (yet) by going to "Settings > General > Reset > Reset Location & Privacy" ... however even this didn't work.
Later on in the evening I was in a different room of the house and out of nowhere I got the "Trust This Computer" prompt on my iPad. I of course tapped "Trust" or whatever and then magically my Mac laptop finally sees my iPad.
I realize I'm not really giving a helpful tip/fix here - just sharing how things went for me in case anyone finds useful.
iPad: iOS 13.4.1 | Macbook laptop: OSX 12.3.1
Recently (2022) I've noticed that the iPad prompt to "Trust this Computer" won't appear unless using an Apple USB-C cable. Apple reps assure me they aren't doing any funny business here, but I have tried every cable I can find, including several thunderbolt 3 and 4 cables and Anker cables. Worth trying an Apple cable if still having problems.
Just simple, close the project on your XCode. Just right-click on the XCode in the taskbar and give a quit option. After open the XCode from the directory, it will detect your device. It also work on Xcode version 11.2.1
close your project or XCode.
Give Right click on the Xcode in MAC tabbar and give the Quit option.
Reopen the project from your finder(project place).
The device will be automatically detected.
Open the Windows in Xcode, go to devices. If Device is visible in Left side, Right click and select "Show in Destination Menu".
Enjoy..
A few days back I upgraded to Xcode 4.3.2 by downloading from the developer's portal and running the installation files. Since then, I am able to test apps on my devices and am also able to test them on the iOS simulator for iPhone without issues. However, the iPad simulator is not working well. A screenshot is attached.
The home button doesn't appear.
The status bar doesn't appear.
The simulator appears like a window with minimize and maximize icons (only the maximize icon is enabled) and also has a title with the version no.
Can anyone please advise, a screenshot of the simulator is present at the below location.
http://postimage.org/image/68pa1t7l9/
The Skins are missing from the iPad simulator, a solution is using the keyboard shortcuts, Cmd+Shift+H for Home, Cmd+1 / 2 / 3 to resize the window to fit on your screen to avoid scrollbars and such.
This has to be a simple configuration issue, but I don't know my way around the build settings very well.
I upgraded my iPad from 4.3 to 5.0. I am using Xcode 4.2. When I plug my device in, it is not showing up on run button, and I have a message that it can't run using the selected device.
What do I have to do?
Open Xcode, go to Window -> Organizer and find your device. Click the "Use for Development" button to get Xcode to recognise it again.
go to your iphone device, settings->Reset->Reset All Settings. Close Xcode, restart XCode, device should be in the list now.
Restarting USB process worked for me.
Run sudo pkill usbmuxd on terminal
or
Open Activity Monitor and select Disk by tapping from segment control and search usbmuxd, select the same and force quite/quite.
Note: before doing above stuff, remove device and quite Xcode.
