Is it possible to read my own fingerprints without using Touch ID?
iOS and other apps never access your fingerprint data, it's never
stored on Apple servers, and it's never backed up to iCloud or
anywhere else. Only Touch ID uses it, and it can't be used to match
against other fingerprint databases.
Because I can not get access to the iPhone fingerprint database, I would like to use the iPhone integrated fingerprint scanner and create my own fingerprint.
iOS and other apps never access your fingerprint data
This statement clearly states you can't get any data from fingerprint sensor. All information is encrypted and stored on device which your application can never access being sandboxed.

We have a requirement where we need to login in to our application using fingerprints. We do understand that apple touch id can be used for authentication purpose and only returns success or failure in the response.
However, in our case one iPhone device will be shared by 5 to 8 users and we need to map an unique userId with each saved fingerprint to identify the user.
Is there any way to map a userid with the saved fingerprint (any unique number returned from an api like Fingerprint1, Fingerprint2 will do)?
Or Is there any alternative solution to login to our iOS application using biometric data?
We dont't want to add an extra fingerprint scanner device.
No, You can't achieve this in iOS. According to Apple about biometric
Touch ID doesn't store any images of your fingerprint. It stores only
a mathematical representation of your fingerprint. It isn't possible
for someone to reverse engineer your actual fingerprint image from
this mathematical representation. The chip in your device also
includes an advanced security architecture called the Secure Enclave
which was developed to protect passcode and fingerprint data.
Fingerprint data is encrypted and protected with a key available only
to the Secure Enclave. Fingerprint data is used only by the Secure
Enclave to verify that your fingerprint matches the enrolled
fingerprint data. The Secure Enclave is walled off from the rest of
the chip and the rest of iOS. Therefore, iOS and other apps never
access your fingerprint data, it's never stored on Apple servers, and
it's never backed up to iCloud or anywhere else. Only Touch ID uses
it, and it can't be used to match against other fingerprint databases.
Now come to main point.
Now days iPhone X series is more popular than other, and they don't support Touch ID, also you can store only one Face ID per device. not like the Touch ID (with multiple finger).
Or after certain wrong try of finger print the device will locked and you have provided Passcode, This is also one per device.
No, there's no way for you to know how many and which finger was used for biometrics, the secure enclave only lets you know if the biometric check has passed or not.
I build an iOS App that collects data via BLE and saves it as text files. What I want to do now is to retrieve the saved data on my PC (Windows) for further analysis. As the developer I know I can download the App container via Xcode for accessing the saved file and it works well. However, I wonder if there’s any approach that I can get the saved files without using Xcode? Can I save the text files to a public location so I can access them directly?
In short, you can't do what you want in this exact way, as iOS devices do not support the USB mass storage protocol. The only way to get files out is using iTunes, which can access your iOS device's Documents folder.
Of course, you could reverse-engineer that protocol, but that's a bit unreliable and might break if Apple ever changes something.
Instead, find another way. E.g. you could have your PC app contain a tiny HTTP server and have your iOS app send an HTTP request to it that contains the file's data. Alternately you could even go via an actual server on the internet.
Or, given all iOS users have iCloud, you could also just save your data to iCloud, then have your PC users install Apple's iCloud for Windows stuff and then just access the file from there.
If I understand you correctly, you want to access the client's data on the PC.
You can create a file server or use a third party service like Amazon S3(https://aws.amazon.com/s3/).
Client upload that collects data through the http/https protocol.
PC download the client's data and analysis.
I have a doubt if any one can access the files and document directories of an iphone app. Need to check if anyone can access the files if they get the device. I have a sqlite file in my app whose data is sensitive i dont want other users to hack or access it.
Please let me know how we can access any apps database.
It will depend on the user, basically, if the user has set a passcode, it will encrypt all data on the device. If the user has not set a passcode, then data will live unencrypted. As a rule of thumb, you must assume if the information lives on the device, that information might be at risk.
Here is what apple has to say about it:
Data protection is available for devices that offer hardware
encryption, including iPhone 3GS and later, all iPad models, and iPod
touch (3rd generation and later). Data protection enhances the
built-in hardware encryption by protecting the hardware encryption
keys with your passcode. This provides an additional layer of
protection for your email messages attachments, and third-party
applications.]1
Also:
On devices running iOS 8, your personal data such as photos, messages
(including attachments), email, contacts, call history, iTunes
content, notes, and reminders is placed under the protection of your
passcode.
I want to detect which finger is scanned to touch id ?
For example user will scan his 2nd finger, can a plugin or apple's touchid framework returns indices of finger, or unique id of which fingerprint scanned.
I just want to detect which finger is printed in ios/swift/obj-c
No, this information is not available.
The secure enclave processor inside the device that analyses the fingerprint simply returns a yes/no that a valid fingerprint was matched
#Paulw11 is correct, we can not access the data of finger prints.
From Apple excerpts:

Any possibility of using the finger print scanner on an ipad to simply get an image of the fingerprint without actually doing any authentication?
The OS seems to do it when you enter your finger print into the device but the only documentation I can find is for Local Authentication.
No, you can't, not even with a private API.
