I just updated Xcode to 7.1 which includes update to Swift 2.1 after which i am getting a segmentation fault error when building the project.

After digging around i was able to figure out that this was because of a type cast issue in ConversationViewController.swift

I have tried everything but nothing seems to work. Could you please help me out on this?

Here is the code below

let status: LYRRecipientStatus! = LYRRecipientStatus(rawValue: Int(recipientStatusDict[participantAsString]!.unsignedIntegerValue))  

Hi @kwkhaw ,

There is a UI problem when you have the keyboard open and you choose to upload an image, the keyboard overlaps the action view. I think this is an Atlas issue. Should I report the issue on the Atlas-iOS page? Also the location button doesn't send the location.

Thank You!

When I go to build in Xcode, I get an error around line 63 of the conversationViewController, pertaining to the NSAttributedString for the date (Screenshot below).

Any ideas?

If I select a conversation before the chat name has been updated then return user! line 58 in ConversationViewController throws an error because it's nil. Maybe because queryAndCacheUsersWithIDs is done on the background and it hasn't finished yet.

Hi,

Can you please upload the Parse Cloud code used to generate the token? Having a hard time figuring out how to create the JOSE Header and JWT Claims Set.

Thanks!

Overall, my changes minimised the implicit unwrapping of optional values, which may cause a runtime crash, when there's a possibility that the variable is nil.

These issues are indirectly shown by the latest Swift compiler build errors

After creating a group conversation, I added my simulator as a participant from my actual phone, the app on the simulated crashes while starting. The error is

fatal error: unexpectedly found nil while unwrapping an Optional value

It is caused by the line

func conversationListViewController(conversationListViewController: ATLConversationListViewController!, avatarItemForConversation conversation: LYRConversation!) -> ATLAvatarItem! {
    let userID: String = conversation.lastMessage.sender.userID // <- this line throws nil pointer error
    if userID == PFUser.currentUser()!.objectId {
        return PFUser.currentUser()
    }
    let user: PFUser? = UserManager.sharedManager.cachedUserForUserID(userID)
    if user == nil {
        UserManager.sharedManager.queryAndCacheUsersWithIDs([userID], completion: { (participants, error) in
            if participants != nil && error == nil {
                self.reloadCellForConversation(conversation)
            } else {
                print("Error querying for users: \(error)")
            }
        })
    }
    return user;
}

There are 2 message in the conversation but this method call for 4 times, at the 4. step conversation.lastMessage is nil

I got a bug when I tested the "Layer-Parse-ios-Swift-Example". I am using xcode 7 and swift 2.

When I enter into the "ConversationViewController", it shows UI Auto Layout constraint issue as following:

2015-09-27 12:47:17.669 ****[4979:2415335] Unable to simultaneously satisfy constraints.

Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSLayoutConstraint:0x150dc7760 H:|-(8)-UILabel:0x150d65700 (Names: '|':UIView:0x150a31f00 )>", "<NSLayoutConstraint:0x150d52880 UILabel:0x150d65700.right == UIView:0x150a31f00.right - 8>", "<NSLayoutConstraint:0x150e5a0b0 UIView:0x150a31f00.width == ATLConversationView:0x14f750d70.width>", "<NSLayoutConstraint:0x150d4d480 'UIView-Encapsulated-Layout-Width' H:[ATLConversationView:0x14f750d70(0)]>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x150d52880 UILabel:0x150d65700.right == UIView:0x150a31f00.right - 8> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

Can you help have a look at this?

using this example on the swift 2 branch, the app builds, Ive set up the cloud code side, parse shows its signing up the users through the login screen when the app builds and runs on my phone but i get a constant activity spinner and the following error:

                        }

                    }
                }
            } else {
                print("Parse Cloud function failed to be called to generate token with error: \(error)")
            }
        }
    }
}

getting a Thread 1: Exc Breakpoint on this line of code " if(authenticatedUserID.isEmpty){

After i select conversation and go back to conversation list, and then close app with home button and open app again, I can't select conversation. This issue is also mentioned in the last comment here: https://github.com/kwkhaw/Layer-Parse-iOS-Swift-Example/issues/2

Hello,

I did the complete install and cannot get it to compile. Please view attached pic. I did the pod install and even a pod update, etc. Any thoughts? Am I missing something?

Thanks,

AG

this is my code :

class test: ATLConversationViewController, ATLConversationViewControllerDataSource, ATLConversationViewControllerDelegate {
    var dateFormatter: NSDateFormatter = NSDateFormatter()
    var usersArray: NSArray!

    override func viewDidLoad() {
        super.viewDidLoad()
        self.dataSource = self
        self.delegate = self
        print("addressBarController: \(self.addressBarController)")
        self.addressBarController.delegate = self

        // Uncomment the following line if you want to show avatars in 1:1 conversations
        // self.shouldDisplayAvatarItemForOneOtherParticipant = true

        // Setup the dateformatter used by the dataSource.
        self.dateFormatter.dateStyle = NSDateFormatterStyle.ShortStyle
        self.dateFormatter.timeStyle = NSDateFormatterStyle.ShortStyle

        self.configureUI()
    }

    // MARK - UI Configuration methods

    func configureUI() {
        ATLOutgoingMessageCollectionViewCell.appearance().messageTextColor = UIColor.whiteColor()
    }

    // MARK - ATLConversationViewControllerDelegate methods

    func conversationViewController(viewController: ATLConversationViewController, didSendMessage message: LYRMessage) {
        print("Message sent!")
    }

    func conversationViewController(viewController: ATLConversationViewController, didFailSendingMessage message: LYRMessage, error: NSError?) {
        print("Message failed to sent with error: \(error)")
    }

    func conversationViewController(viewController: ATLConversationViewController, didSelectMessage message: LYRMessage) {
        print("Message selected")
    }

    // MARK - ATLConversationViewControllerDataSource methods

    func conversationViewController(conversationViewController: ATLConversationViewController, participantForIdentifier participantIdentifier: String) -> ATLParticipant? {
        let user = PFUser()
        return user
    }

    func conversationViewController(conversationViewController: ATLConversationViewController, attributedStringForDisplayOfDate date: NSDate) -> NSAttributedString {
        return NSAttributedString()
    }

    func conversationViewController(conversationViewController: ATLConversationViewController, attributedStringForDisplayOfRecipientStatus recipientStatus: [NSObject:AnyObject]) -> NSAttributedString {
        return NSAttributedString()
    }

}

and this is error : Type 'test' does not conform to protocol 'ATLConversationViewControllerDataSource'

I know you are no longer working on this project, but maybe you would have a clue to what's wrong.

From the link: "To generate issue do following:

1. Run app
2. Select conversation
3. View that the name of participant is shown in AddressBar
4. Go back to ConversationListView
5. Toggle the home button (while app is running)
6. Open app
7. Select conversation (the participant name is no longer shown)

If you go back and tap a conversation again then name of participant is shown again."
