User Registration and Login example with Swift + Parse

For my complete video course on this topic please visit this page:

In this example I am showing how to integrate your mobile app with Parse cloud service and store user login details in Parse cloud storage.

Solution:
for some reason for the error that I had, I just deleted the ? after Bool and changed println to print. It solved the problem right there:
" {
(succeeded: Bool, error: NSError?) -> Void in print ("User successfully registered.")
"
Thank you for your tutorial :)

Once the user is logged in, you are getting to the protected view page but in video 1, you have a segue that automatically goes to a specific view page. In essence, you haven't implemented the code where if the user login is successful, it should go to a landing page in this video example. How easy is parse to create tables with referential integrity between tables?

hey sergey, sorry for being overwhelming in my last request, i understand your busy and its very nice of you to take the time to help people. i think i was able to narrow down the problem.  it looks like its a result of this line of code

PFUser.logInWithUsernameInBackground(userEmail, password: userPassword) {

the error says:Cannot invoke with an argument list of type '(String!, password: String!, (PFUser!, NSError!) -> Void)'


any ideas?

Hi, Sergey! Thanks a lot for this video. I'm using parse to store my data in cloud. When I create a new instance, I will get a new random objectId, and I only can check it on my browser. Is there someway that I can use this new objectId to search, update and get the data from the cloud instead of using "0394xserg", something like that?

[satyabratajjjjjjjjjj]

hello sergey there is a new option for swift in parse.com is that same way to integrate???

[LekanAdeyeri]

If you download the github project, and you get the error "User cannot be saved unless they are already signed up. Call signUp first."

Its because the function, should actually be "signUpInBackgroundWithBlock"

[AlterTheYoung]

hey Sergey, is there a certain place that the login view controller code should be for example like "below view did load?  im getting errors (=,   also, can you mention any changes to the code that might be affecting me please?

[lifeofeddy]

Hey Sergey how do i print out an alert if email or username exists?, i am already aware that parse does it by itself but i want to show it for the user so they also know the issue

Hi Sergey, i have some problem with this. Can you help me? Thank you

Cannot invoke with an argument list of type '(String!, password: String!, (PFUser!, NSError!) -> Void)'

[SergeyKargopolov]

Surafel Tensai For some reason I cannot reply to your comments. Try using question mark after NSError instead of exclamation mark. like this: NSError?

[kaizen]

Hello,

I am hitting error with this line: (success: Bool, error: NSError?) --> void in

The error is: Cannot convert value of type '(Bool, NSError!) -> Void' to expected argument type 'PFBooleanResultBlock?"

Please help.

Thanks

Hi Sergey, I post this question in about 6 days a go, and not sure if you were able to see it on your side.... 

Thanks for the great information, I'm having a small problem, and this is the error message, What should I do? 

Cannot invoke 'signUpInBackgroundWithBlock' with an argument list of type '((Bool!, NSError!) -> Void)'

[Tripinfall]

If I was able to set up my project in Parse as Swift instead of Objective-C do I still need to use the connector?

[Hakusword]

I have everything done, one problem I get is when I do not show the @ symbol when i try to log in and Parse gives me code 125 invalid email address error, Can you tell me how I can implement this error so users will see the alert message?

[AlterTheYoung]
