I have a SQLite DB that I'm using to store app data, and I could do with taking a look inside it to debug a problem I'm having - but where does the iPhone Simulator store its data, typically?
This question is related to
iphone
ios-simulator
iOS 8 ~/Library/Developer/CoreSimulator/Devices/[Device ID]/data/Applications/[appGUID]/Documents/
$ open ~/Library/Developer/CoreSimulator/Profiles/Runtimes
For example: iOS 13.0
, watchOS 6.0
These take the most space, by far. Each one can be up to ~5GB
$ open ~/Library/Developer/CoreSimulator/Devices
For example: iPhone Xr
, iPhone 11 Pro Max
. These are typically <15 mb each.
Simulators are split between runtimes and devices. If you run $ xcrun simctl list
you can see an overview, but if you want to find the physical location of these simulators, look in these directories I've shown.
It's totally safe to delete runtimes you don't support. You can reinstall these later if you want.
For react-native users who don't use Xcode often, you can just use find
. Open a terminal and search by with the database name.
$ find ~/Library/Developer -name 'myname.db'
If you don't know the exact name you can use wildcards:
$ find ~/Library/Developer -name 'myname.*'
On Lion the Users/[username]/Library
is hidden.
To simply view in Finder, click the 'Go' menu at the top of the screen and hold down the 'alt' key to show 'Library'.
Click on 'Library' and you can see your previously hidden library folder.
Previously advised:
Use
chflags nohidden /users/[username]/library
in a terminal to display the folder.
One of the most easy ways to find where the app is within the simulator. User "NSTemporaryDirectory()"
Steps-
When the app stops at the breakpoint, type following command in Xcode console.
po NSTemporaryDirectory()
See the below image for a proper insight
Now you have the exact path upto temporary folder. You can go back and see all app related folders.
Hope this also helps. Happy Coding :)
In iOS 5 :
/Users/[User Name]/Library/Application Support/iPhone Simulator/5.0/Applications/[AppGUID]/
Catch a Breakpoint somewhere.
Enter po NSHomeDirectory()
in console window
(lldb) po NSHomeDirectory() /Users/usernam/Library/Developer/CoreSimulator/Devices/4734F8C7-B90F-4566-8E89-5060505E387F/data/Containers/Data/Application/395818BB-6D0F-499F-AAFE-068A783D9753
There is another (faster?) way to find where your app data is without Terminal:
For macOS Catalina, I found my db in:
~/Library/Developer/CoreSimulator/Devices/{deviceId}/data/Containers/Data/Application/{applicationId}/Documents/my.db
To get the applicationId
, I just sorted the folders by date modified, though I'm sure there's a better way to do that.
With Xcode 5 you may use the code below:
#import <Foundation/NSFileManager.h>
and:
NSString *homeDir = NSHomeDirectory();
NSLog(@"%@",homeDir);
The result may look look like:
"/Users/<your user name>/Library/Application Support/iPhone Simulator/7.1/Applications/hhhhhhhh-hhhh-hhhh-hhhh-hhhhhhhhhhhh"
Where hhhhhhhh-hhhh-hhhh-hhhh-hhhhhhhhhhhh
is some hex string identifying your iOS app.
Looks like Xcode 6.0 has moved this location once again, at least for iOS 8 simulators.
~/Library/Developer/CoreSimulator/Devices/[DeviceID]/data/Containers/Data/Application/[AppID]
For Xcode 4.6 it gets stored in the following path...
/Users/[currentuser]/Library/Application Support/iPhone Simulator/6.1/Applications/
To know it programmatically use the following code
NSLog(@"path:%@",[[NSBundle mainBundle]bundlePath]);
You can try using the below code
NSString *fileName = @"Demo.pdf";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
NSLog(@"File path%@",pdfFileName);
For iOS 8
To locate the Documents folder, you can write a file in the Documents folder:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fileName = [documentsDirectory stringByAppendingPathComponent:@"Words.txt"];
NSString *content = @"Apple";
[content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];
say, in didFinishLaunchingWithOptions
.
Then you can open a Terminal and find the folder:
$ find ~/Library -name Words.txt
Simply do this:
NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSLog(@"%@", docDirPath);
And you will get somethink like this:
/Users/admin/Library/Developer/CoreSimulator/Devices/58B5B431-D2BB-46F1-AFF3-DFC789D189E8/data/Containers/Data/Application/6F3B985F-351E-468F-9CFD-BCBE217A25FB/Documents
Go there and you will see the document folder of your app regardless of the version of XCode. (Use "Go to Folder..." command in Finder and specify a path "~/library").
Swift version for string path:
let docDirPath =
NSSearchPathForDirectoriesInDomains(.documentDirectory,
.userDomainMask, true).first
print(docDirPath)
and folder URL:
let docDirUrl =
FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first
print(docDirUrl)
To Open the dictories where you App are that you build in xCode on the simulators, do the following:
Found it:
~/Library/Application Support/iPhone Simulator/User/
If the Simulator is running you can get the path to any app's container:
xcrun simctl get_app_container booted <app bundle identifier>
Example output:
$ xcrun simctl get_app_container booted com.example.app
/Users/jappleseed/Library/Developer/CoreSimulator/Devices/7FB6CB8F-63CB-4F27-BDAB-884814DA6FE0/data/Containers/Bundle/Application/466AE987-76BC-47CF-A207-266E65E7DE0A/example.app
"booted" can be substituted to most simctl
commands anywhere a device UDID is expected.
You can see the list of devices with xcrun simctl list
and get help on specific commands with xcrun simctl help
.
Update: By popular request in Xcode 8.3 you can now specify the kind of container you want by appending "app", "data", "groups", or an app group identifier.
To get the data container:
$ xcrun simctl get_app_container booted com.example.app data
I have no affiliation with this program, but if you are looking to open any of this in the finder SimPholders makes it incredibly easy.
if anyone is still experiencing this problem in lion, there is a great article with 19 different tips to view your ~/Library dir. find the article by Dan Frakes here http://www.macworld.com/article/161156/2011/07/view_library_folder_in_lion.html
Remember the directory to the simulator is given below
~/Library/Application Support/iPhone Simulator/User/
