Programmatically erase iPhone's data swift - ios

I am developing an iPhone Application to wipe all data from iPhone including photos, videos, contacts, messages, apps, etc. programmatically. I wish to achieve this with an iPhone Application only.
The approach I am thinking of somehow I manage to Clear data from iPhone and rewrite the memory with some junk files or binary data 1010 say. (Its just an idea!)
All I have managed to do is delete photos from Photos which are further not deleted from Recently deleted folder in Photos App.
Also, I found this Programmatically How to wipe out iPhone or iPad data in i phone apps in i phone apps which declines it's feasibilty.
But, Is there a way to programatically restore my iphone to factory settings? says using the C files mentioned here https://github.com/lite/osxrce/blob/master/resetapp/main.m can may be make it possible. They say they tried it on a jailbroken device though.

What you are hoping to do isn't possible on an non-jailbroken iPhone. You will be violating the iOS sandboxing among other things.
A similar outcome may be possible by creating your own MDM server, and building your app to interface with it. On first installation of your app, you can have it install the MDM profile. The app can then feature your 'Wipe' button which can signal to the MDM to send a wipe push notification to the device.
It would take a lot more work that what you're asking about, but it should be possible.
Reference: https://developer.apple.com/enterprise/documentation/MDM-Protocol-Reference.pdf

Apple do not allow to delete files which aren't created or part of your application, so you will not be able to delete data of other apps.

I don't think you're allowed to do that anyway. Even if you were able to do it, it would not be accepted on the app store.

You can backup the iPhone via AppleMobileBackup.exe -b, then modify the according
database file(such as addresscontacts, messages), and restore the modified ituensbackup files to the iPhone via AppleMobileBackup.exe -r.

New requirements for iOS app - keep them accessible to users/customers

I got an email from Apple that apps now require iOS13 + storyboard for app launch screen for existing apps. (I do not use storyboard for main app functionality)
I have developed a couple swift1/swift2 based for schools a long time ago. (Still works well)
Can I somehow ditch the app store and then provide direct access or download for school pupils?
i.e. is there any way forward to simple keep the apps-as-they-are? Maybe limited download availability?
Or will I have to take plunge back into app-building?
The requirement of a Storyboard launch screen is only when you need to submit an app update. If you are not wanting to update your app any more, then it won’t stop working because of this new requirement.
Regarding distribution outside of the App Store, you could use Adhoc distribution which requires you to know the device ID’s of the devices you want to install it to.

How can i export app file in Xcode

Do you know how to export app file in Xcode?
(like .apk file in android)
I want to send my testing app to someone for feedback.
i have never tried it before. please let me know easy way to export app file.
(not all project, only a file which can be played in another iPhone)
First Archive it (XCode->Product->Archive).
(For Archive button to be in visible state : either your device should be selected or generic ios device should be selected, incase any simulator is selected archive button will be disabled.)
A Window will appear :
Choose Export->AdHoc.
.ipa will be generated.
u can use https://www.diawi.com/ for uploading and send app to anyone.
I am posting a very late response to this old question in case anyone else finds their way here and infers that it isn't possible to export an app to your own iPhone or iPad without a developer account. That isn't true. I unearthed these posts when looking for an answer to the same question, and initially read them that way.
If you want to test an app you have written in XCode on your own iOS device you do not need a developer account. Provided the device you wish to test it on (or share it with) is physically nearby so that you can connect it to your macOS device to pair with it as a trusted device, it will remain paired when physically disconnected and accessible over a shared network by WiFi. You can build and run apps from XCode on to the iOS destination device and they will remain in place there and executable afterwards. There is a limit to how many exported apps there can be at one time, which seems to be 3.
Apple explain how to do all this here. You do need to have a registered App Store account, but that's the same one you use to buy apps and build projects in XCode, and it's free unless you want to distribute your app through the App Store.

Lock iOS app in single app mode programmatically

Note : I don't want to submit this app to app store.
What i want to achieve :
I want simple app with one view having two button Lock and Unlock.
Lock - This button will lock device. Only this app's screen will show nothing else will be accessible even after restart same screen will show up. Home button, gestures will get disabled similar to single app mode.
Unlock - This will unlock device and switch to normal behaviour of device.
iOS :
I want this for iOS 4.3 and above.
I have checked following solutions, but these don't match my requirements
Configuration profile
Lock-down iPhone/iPod/iPad so it can only run one app
But it is manual (reboot device, open app which you want to run in single app mode). I want to do it programmatically the way i mentioned above through my app.
Guided access (iOS 6 and above)
How to lock down user to Single App mode in iOS 6, Programmatically?
I want it do for all os and programatically.
Is there any way to do this ? As i don't wan't to submit it to app store is there any private api, some hack for springboard to achieve this ?
Thanks in advance !!
As I know in iOS 7 there is a new feature which allow to do exactly what you want.
However, it's only applicable for iOS 7 (and I believe it's only applicable to a supervised devices).
1) You will need to install restriction configuration profile with autonomousSingleAppModePermittedAppIDs key (take a look here)
This is one time step and a user will need to manually accept this configuration profile.
There is another option to use MDM to install it silently, but it could be an overkill for you.
2) You should use API:
UIAccessibilityRequestGuidedAccessSession (to lock/unlock)
It is defined here
3) And most beautility part. All of it is officially document. So, you can even submit it to AppStore.
P.S. Why do you care about 4.3 or 5? They have tiny market share by now. Most likely even iOS 6 has below 20% market share already.
Update 1
Potentially, you can try to use API which sends clicks and keys (search for GSEvent in iPhone-privateapi tag). May be using these API's you can do triple home to toggle accessibility on and off.
If this work, I think you should be able to cover iOS 6. I am not sure whether both this API and triple home click were available prior that.
It looks like this private API is unaccessible anymore in iOS 7. So, probably you can ignore this idea.
Just wanted to write on this even though this is old as i needed to implement a similar solution and i got it working. The steps for me as follows and a note here is that this involves MDM and other specific steps.
My requirement was as follows. Each of the iPad at different locations has a set of apps installed.For ease of it lets assume each Dept. has their own apps. Participants open a app related to their dept. to take a test, the APP automatically Locks the iPad to single-app Mode and at the end of the test, it will unlock it self.
Supervise the iPad/iphone using the Apple Configurator.
Install the MDM related files ( Each MDM has its own set of instructions, usually involves downloading a profile).
Every MDM has a option of Single APP Mode or MultipleAppMode. Select the second option and add the app IDs to the list. (A single APP mode works pretty well with MDM's but i did not want the app to be locked to a single APP all the time).
I used the UIAccessibilityRequestGuidedAccessSession api to lock unlock the device from single app mode.

Thanks,

In MDM configuration, There is an option
autonomousSingleAppModePermittedAppIDs
Optional. Supervised only. If present, allows apps
identified by the bundle IDs listed in the array to
autonomously enter Single App Mode.
Availability: Available only in iOS 7.0 and later.
But this needs Supervised Device mode.

iOS Application - intercept when a user deletes the app from device

I'm developing an apple iOS application using Xcode.
How to know if a user removed an application from his iPhone/iPad Device?
thank you
If you have several your apps on device - you can use SHARED KEYCHAIN to detect marker you've written in deleted app. Shared keychain can be accsessed by apps sharing same keychain access group. Or you can get approximate statistics using some statistics framework by checking whether some application stopped logging any events for a long period of time.
No you cannot. The only thing you can catch is first run of your app. There is no obvious reason for knowing when your app is uninstalled (except of spamming users). You can just keep stats to see your app usage if that's the case.
No, an app cannot detect when it is being deleted from the device.
An app runs in a sandbox / secure container. (Almost) everything outside that sandbox is just a 'mystery' for the app. Your app shouldn't need to know, so IF this is an issue at all, it is basically just a design issue for you to deal with.

How do I programmatically remove an application from an iOS device? [duplicate]

This question already has answers here:
Closed 10 years ago.

Programmatically delete my own app
Currently I am working on a iphone application and one of the critical requirement of the application is if a user cannot successfully authenticate after 5 attempts, the application is removed from the user’s iPhone.
How can I achieve this goal?
Being able to alter things outside of the application's own sandbox is a huge security risk that Apple (understandably) has not allowed. Therefore you will not be able to do this. The best you can do is store the result in a persistent value and not allow to app to continue after launching. For bonus points, you can store this value in the iOS keychain so that it will persist between installs if you like, then the user will be forced to reset their ios device to factory defaults to be able to use it again.
Can't be done. The best you can do is to make your app stop functioning after five failed authentication attempts.
you cant. the only one who can have this privilige is the user. You could just make the app to not open anymore, making the user angry and then deleting it afterwards.
Its not possible. You should handle it programmatically like locking the application. Once user is failed for 5 attempts, change your startup viewcontroller and do not allow the user to navigate any where else. Here you can display some message to delete the app.
An application, installed in a non-jailbroken device, is a sandboxed eco-system.
If your app is for App Store, this thing cannot be done. If this app is for a JB device (for In-House apps would be possible, but I think you need root permissions to delete apps), try to remove the app file from disk after the app has gone on background (but I'm quite sure files are locked, so you'll not be able to do it). If this approach, as I guess, doesn't work due to locked files, you can try to search for private APIs.
It's not possible. You only solution is lock the app if authentication not success.
