Is there any way to use apple's Touch ID (fingerprint scanner) on iOS Simulator?

Question

I am working on an app which would require Touch ID Authentication, so is there any way i can use Touch ID (fingerprint scanner) in the simulator ?

Also, please do share some kind of example code for using LocalAuthentication framework.

Solution 1

As of Xcode 7 the Simulator supports 'touchID'. Answer below contains further info.

As of the latest beta (6) there is no way to simulate a fingerprint scan on the simulator. To be honest I doubt this will be included even in later betas.

You will need to test on device.

To use the Authentication framework right now you need: * XCode 6 * iPhone 5s with iOS 8

The steps you need to perform are:

Find out whether the device supports fingerprint validation and whether a fingerprint is enrolled:

@import LocalAuthentication;

// Get the local authentication context:
LAContext *context = [[LAContext alloc] init];

// Test if fingerprint authentication is available on the device and a fingerprint has been enrolled.
if ([context canEvaluatePolicy: LAPolicyDeviceOwnerAuthenticationWithBiometrics error:nil])
{
    NSLog(@"Fingerprint authentication available.");
}

Validate a fingerprint only:

[context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"Authenticate for server login" reply:^(BOOL success, NSError *authenticationError){
    if (success) {
        NSLog(@"Fingerprint validated.");
    }
    else {
        NSLog(@"Fingerprint validation failed: %@.", authenticationError.localizedDescription);
    }
}];

Validate a fingerprint or the device’s passcode depending on the user’s choice: This is a little beyond the scope of a question here, please find more information at: https://www.secsign.com/fingerprint-validation-as-an-alternative-to-passcodes/

Solution 2

XCODE 7 beta supports testing the Touch ID Authentication in iPhone Simulator.You can try this for your testing.

Ouch...Wanted to test touch id with the apple watch,i have an iPhone6 but not a watch. Really, hope that we can just use the simulator to test touch id.

how can we trigger this action with selenium?

Is it possible to trigger this within the setUp of a UITest's XCTestCase?

Even after I enabled "Touch ID Enrolled", I am still getting "Pay with Passcode" prompt instead of the fingerprint. Does anyone know why that might be?

There is support now See @karthik answer below! This answer should be updated :))
