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.

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– Service Factors The To Provider Id Consider While Fake Hiring 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) – Service While Fake Id Consider Provider The Factors Hiring To { 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/

  • 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. –  user1872384 Feb 17 '15 at 13:19
  • There is support now See @karthik answer below! This answer should be updated :)) –  thinklinux Mar 15 '18 at 12:55

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